Proxy create (small tutorial)

[Tong]

just did it, no sound (everybody sleeps tonight), but i added subtitles :D

hope will be helpfull.

http://www.vrayc4d.com/manual/examples/vrayproxy/vrayproxy.html

added: Xref used like Proxy
http://forum.vrayforc4d.com/viewtopic.php?p=33920#33920

ps: also you can make proxy with Ply2Vrmesh.exe utility manualy, for example you have obj file Object1.obj
so you must make coomand line like this:
Ply2Vrmesh.exe Object1.obj Object1.vrmesh

or you use little trick in tutorial with autoproxies ;-)

[BerTiN03]

Thanks a lot Tong ! :wink:

[hiro]

thanks tong, but i still cant make it work:

i create a cube, i put a vrmesh export tag on it,
than i create a vray proxy element, uncheck "use filename", drag the export tag to it, well, the mesh appears, but when i hit render, the proxy does not appear as a rendered element. its only the original cube.
Whats wrong with my settings?

[stefan]

make sure to link the tag not the object.
make sure your pluginfolder has read and write access

hiro OSX ?

[ak-vision]

hi hiro,

did you render with vray or cinema? :wink:
Here it works, thank you for the tut, tong!

Thanks Tong

[hiro]

Ok, the winner is.... AK Vision! :oops:

i've activated Vray in "Effects", but i did not choose the vray rendersystem in the "General" tab! shame on me, no routine on R11!

Now it works!
Thanks!

[steppes]

hey cool tutorial...


but i cannot get the vrmesh files in the vray directory...so i cannot save the vrmesh...

tong says "vray creates vrmesh in the vray directory during rendering...."

nothing there.... :(


EDIT: ok i got it, but you have to be very fast! because the vrmesh-file is there DURING rendering. so if the file renders to fast you will not get the file... or there a way to freeze this?


nwe question: my exported tree is very much smaller than the original (1%) where can i change these settings?



steppes

[hiro]

steppes, open the vray plugin folder and watch the content during rendering. the vrmesh appears, and when the render process is over, it disappears! So, you have to be quick, when you see the vrmesh, take it and drag it to another place.... :shock:

(i think, this workaround has to improve, but it works!)

[Tong]

yea, we have in wish list
manualy choose save or not proxy vrmesh and use it or new generated

ok i got it, but you have to be very fast! because the vrmesh-file is there DURING rendering. so if the file renders to fast you will not get the file... or there a way to freeze this?


yes, just use Higher render settings, that will take longer to render

nwe question: my exported tree is very much smaller than the original (1%) where can i change these settings?


can you send it to Renato?

[leed]

Ok ... I just can not get this to work.... Hopefully I am missing something as I have done the cube tutorial and got it working... and when I do the cube tutorial with a small tree ( 1 object just the trunk)it crashes.... I can see that people have got it working here.. but I have followed the same tutorial... (with the cube) and got it working.... but with a tree trunk, not that big it crashes.......

I have not had any luck with the other technique either.... just crashes c4d....

Any ideas......

Mac OS Oct G5 Intel C4D 11 Vray 1.1.....

A very frustrated
Lee[/i]

[leed]

Well I have got it to work.... Kind of...

I have to generate the .Vrmesh file in PC... then I can render them in OSX....


I have done this in PC... but can not get the generation of the .vrmesh to work on a MAC Osx... CRASH!!!!

Can anybody give me any pointers.... as this work round is not really very good.... and why on a PC and not a Mac..........

Lee

[STRAT]

holy smokes, this proxy gig is fabulous - a fast simple 1.3 billion tree scene in seconds!!!!!!

[ernia]

Hi Leeds,

On mac only, I had a similar situation until I figured out that for some reason
standard c4d materials always crash proxies, either exporting or rendering.
As soon as I used ONLY vray materials on the proxies she purrs like a kitten.

--a big fat juicy kiss to the Vray team!

ernia

[colibert]

Sorry, me again with a dumb question, im following the tutorial but it makes no files during rendering, read and write is on for the folders and even making a long render so i dont miss it nothing appears :oops:

[STRAT]

it's a quick thing. it makes the files, but as soon as the render is processed they disappear. if you have very low render settings you'll find the creation and disappearance of these files might not be detectable. but high render settings in and they'll be in existence a bit longer. long enough to copy and paste :)

[colibert]

thats what i thought, ive tried it even taking a minute to render nothing comes, also the same with the cube, all works fine, get the lined box as my instance but it wont render, just the original one does

[colibert]

sorry guys, its still not having it, ive watched the video about a hundred times, has knowone else had the problem?

Is there any chance someone could have a look and see if this renders for them?
Assuming i havn't done anything stupid it should work

thanks guys.

[Walli]

hi,

is it possible to batch process a folder that contains obj files with ply2vrmesh.exe?

And if, how would that work?

Thanks,
Walli

[Tong]

hi,

is it possible to batch process a folder that contains obj files with ply2vrmesh.exe?

And if, how would that work?

Thanks,
Walli

easy...just merge them in to one c4d file....change light cache Subdivision to 10000 hit render and after lightcache starts....just start to collect them

[Walli]

okay, and I found another way - thank you Wikipedia ;-)
Create a bat file with the following
for /L %%N IN (Start, Step, End) DO ply2vrmesh.exe LadeMich_%%N.obj LadeMich_%%N.vrmesh

and put the bat file and the ply2vrmesh exe into the same folder with the obj files

The obj files must be numbered and then you have to replace Start with the first one (1), End with the last one (lets say 50) and Step with 1.

But it would be nice if the bat file could be more intelligent and just take all objs automatically and throw them at ply2vrmesh. I think that should be possible to but I haven´t found out so far.

[Walli]

and after some more testing:

for %%N IN (*.obj) DO ply2vrmesh.exe %%N %%N.vrmesh

this seems to work, simply converts all objs to vrmesh.

But with no warranty from me ;-)

[Tong]

small tip ;-)

in image Xref used like proxy, so no need to have in scene huge objects, just use XrefProxy (c) Tong ;-)

and you can always edit xref, like normal xref ;-)

sorry, il stop asking soon!!

[Tong]

Mine still wont work..driving me nuts!! anyone have any idea what else may be the cause?
sorry, il stop asking soon!!

what can i say, i downloaded your scene, hit render and file appears in folder and i copy it ;-)

[colibert]

weird...thanks anyway tong, il try it on the laptop later make sure its not some weird restriction they have put on at work although i have the admin password and have turned off all folder restrictions, will be something silly im sure.

Thanks anyway for trying, at least im not being a complete bafoon :wink:

[colibert]

There we go, hows this for weird..

Got in, fired up laptop made a proxy hit render, worked first time!
how odd, has to be a problem with the OS then surely, only thing thats different, they wont let me upgrade to the later OS at work yet, some rubbish about it not working properly with our PDF and print server...

that will be changing in the morning, sorry for bugging you all!!

it works, im happy 8)


proxies are brilliant!!!!!!!!!! 15000 cubes in a minute &10 on my laptop!!! 8)

[Rich_Art]

Yeah VrayProxy rules big time...... :P

Peace,
Rich_Art. :wink:

[DanieleF]

Hi guys,
to make your vrmesh files collection, just use the included Ply2Vrmesh command line application included in the VrayBridge folder.
Just type:

Ply2Vrmesh objName.obj vrmeshName.vrmesh

Of course the best thing is to make a batch file to convert more than one file automatically, like Walli suggested.

Cheers
Daniele

http://www.deltazone.org/~fc4d/images/badie_Image3.jpg

http://www.deltazone.org/~fc4d/images/badie_Image4.jpg

• The Proxie Object is Twice biger than original
• Lost Mapping…
• all Object have the same Y axis Coordinate…

I try to test that on R11 demo… but VRay Demo have no Proxies Function… :(

Cheers

[Arjo]

Could it be that your objects have scaled axes?
I mean what happens if you select your original object and use the function "reset system"?

[mort]

May be a silly question - but pls for some tip - when creating proxies for object that is compound from several objects - how to manage coordinates of the proxies created
I put Y axis of all the objects to 0 and then create proxies - is there any better tip................

[Tong]

stop stupid me,

you mean when you have Tree with object leaves and object bark? just make one proxy and copy it with ctrl and mouse it will be the same proxy in the same place then just reassign copy to another proxy file and you will have correct look

[mort]

Ok may You explain me this
http://www.paradoxx-design.com/pics/pom/proxy.jpg

By me if the objects have different axis centers thing becomes different

[Tong]

i don`t get it, you copy first proxy? but it in object mode it in different place then second...it seems you don`t understand me :(

i will make short video later today

[Huv]

Just for info, for those who have paintonsurface (http://www.dns-plugins.de/plugins.php), just to say that you also can "paint" proxys :)

[badie]

Thx everybody
Now it work :) not completly but …
• Coordinates Position & Rotation = Working " but before reset system Coordinates, & making all Y axis objects to 0

• Scale coordinates still twice big… :?

• Lost texture Mapping Coordinates " no UVW mapp " I fixed it manually

[3dkobi]

Tong - every video tutorial is more than welcome, especially about the new things we have now...:)

thanks

peace
kobi

[don_tomaso]

Btw Huv, do you know if "PaintOnSurface" is working in R11? Thinking of getting it..

[BerTiN03]

You have to be very strict when you create your objects to be "proxied".

All axis origin at the same place for every mesh.

Every object scale to 1.

If you respect that, no problem !

I guesse you have several different axis position for every mesh of your paint pot, arranged as you want the place of each object to be, and perhaps you have reduced scale of the regrouped object (the whole null object) to 0.5.

When you use every mesh in the proxy's, proxy's don't mind the scale of the null and the way you have arranged the axis position, he simply take it at the original scale and place it at the object origin (0,0,0).


The best way to be happy is to replace the axis of all mesh at the same position (0,0,0), and to set the scale of the null at 1, and each scale of each mesh at 1 too.

You resize each of them in the viewport, or multiplying each dimensions by a coeff. in the coordonates manager, if you want to be more precise.



You resize directly the object in the viewport :wink:

[piotrs77]

Hi everybody!

I read entire topic - GREAT proxies tutorials - & I try to use proxies - everything works fine exept:

When i use "Use Filename" options in VrayProxy Object - this proxy-object renders only in view (render region); when i try render to picture viewer - object isnt visible (exept this scene renders correct).

Does anybody have similar problem?

I use C4D11, vray 1.1, PC WinXP, IntelQuadCore 2GB RAM

Btw Huv, do you know if "PaintOnSurface" is working in R11? Thinking of getting it..
Yes working on R11 but 32bit only for the moment :)
Hope to see a 64 bit version soon :)

[big K]

are you sure you are right?
paintOnSurface 1.51 is working under R11 64bit.
at least i use it ! :-)

Sorry, maybe to forgot to say i was on a mac plateform...

[BerTiN03]

I follow the tutorial exactly, but have some BIG troubles...

--> A Proxy with local link to present mesh work fine :

http://www.polygone-production.com/DIVERS/Vrmesh-01.jpg

--> After that, I copied the Vrmesh files in the VrayBridge folder during rendering, and paste into my tree folder.

I erase the old proxys and linked them to the Vrmesh, and that's the result :

http://www.polygone-production.com/DIVERS/Vrmesh-02.jpg

What did I missed ?.. :?

[Nico]

When i try Proxy, it make C4D crashes.

I do like this :

1 - I use a tree and i put proxy tags on the 2 objects.

2 - I copy the 2 objects ".vrmesh" in the VrayBridge directory and put them in the directory that i want

3 - I open a new scene and put a VrayProxy tag

4 - I tick "Use a filename" and search the "file.vrmesh" and when i just click on it, i have the message from C4d that it crashed.

Do i miss something?

Thanks,

Nicolas

[Nico]

Hi, i see that my subject doesn't interest a lot of people but i continu.

I just tryed with a cube, a sphere and a cylinder..... Result, same thing, it crash.

Thank you

[zickboom]

Just a test.
One scene, 30 armchairs, one light, vray sky and sun, GI on.
Same render specifications in the two test.

First render, one armchair with instances
render time 1,28 min 154 000 poly

Second render, one armchair.vrmesh with instances
render time 1,48 min 800 poly

Is there Proxies takes less memory but more time (for small files) ....


Quad G5 PPC ram 2,5Ghz, c4d v11, Vray 1,1 but... cinema display 30''

[Tong]

hm, i will test

but 14% difference it like statistic error? ;-)

[Nico]

And my case smells shit?

[Tong]

And my case smells shit?

fi ;-)

no just not enough information, i think the problem in right to wright on hdd (imho) but i can`t look on your screen :(

do you have "bug report"?

[BerTiN03]

Should it be the same for me ? it doesn't crash, but render black. But on XP, no wright problems, normally, no ?

[Tong]

i think in your case proxy mesh was not completed before you copy it.

did you tried to make proxy with ply2vrmesh.exe manually ?

[BerTiN03]

erf, I haven't tried yet.. i was afraid by the process.. :oops:

But I waited a bit before copying the vrmesh (1st render was during 5 minutes, I waited 2 minutes before copying vrmesh).

I'll try with another file, and i'll try also with ply2vrmesh too.

[InTheCity]

I'm loving this proxy workflow, it's very intuitive.

Curious though. In a scene I'm making today, I want to output a section of grass for proxy duplication, several trees that will be amount to billions of polys and maybe 10 cars that'll be 1000's of Proxy objects.

As individual objects, the scene exceeds my RAM (about 4.5million polys)

Is there a limitation on how many proxies my system can handle when you consider them as individual singular objects? Does that amount correspond to how many poly's my system can handle with regular poly objects?

[sketchbook]

ok, so once vray creates the proxy objects in the vray directory - do we copy both the vray mesh and the obj for use later?

or do we just need one?

thanks!

[sketchbook]

oh my word.

this is freaking insane.

i worked for hours the other day on a deadline trying to render a "hall of computers" for a client, and even with super low rez computers, i was not able to get this to render at all.

i just proxied everything out, and it rendered in minutes.

absolutely incredible!!!!

BTW - did someone say Vray Proxy was slow on the mac? I am on a mac and it works like a charm here.

[zickboom]

only for PPC users.
copy your vrmesh files in the tex file and then it's fine.
Just have problem with geometry plane which doesn't want to work.

[ZFact]

I'm not up to speed with proxies.. Can someone explain what they are and what they do and how they differ from cloner objects please!

Thanks
Z

[Tong]

http://www.evermotion.org/index.php?unfold_exclusive=154&unfold=exclusive

with clone object you can`t make 100000000 objects with 1000000000 polygons ;-)

[egselent]

Proxy looks amazing. I am having a problem with one thing. If i have a cube for example that i have three textures on different polygon sections, once i save the cube as a proxy obviously i need to re texture this proxy object when i bring it into a seperate file. Is there any way to put the three textures back on? Do you have to split the cube into three proxy objects to do this?

Thanks in advance!

[3dkobi]

I think that selection tags won't work with proxies...
I think that split the cube is the only way...

peace
kobi

[egselent]

just another quick question. is there anyway to scale a proxy object. i am using it for trees at the moment and i want to be able to add a bit of variety in their sizes but i cant seem to scale any off them.

[3dkobi]

Maybe with mograph you can do it. since i don't have it, i make 1 proxy and than duplicate that proxy into instances. than you can use the "randomize" command on the instances for scaling and rotating.

peace
kobi

[ZFact]

hI;
I cant seem to get proxies working! It seams to be a problem with the
read and write access within vista folders. I have spent the last 3 hours playing around with different permissions but cant get it to work.

Does anyone know how to successfully alter the permissions to write the proxy to the plugins folder?

Cheers
Z

[choppir]

Guys, i've been trying this proxy thing.
I got a chair, but it is in 2 parts: The legs and seat.

My proxy render it both lying on the floor level.... :? The objects looses it heights....?

Can anyone tell me how i can fix this?

cheers

choppir

[3dkobi]

You have to make sure that the axis center on both parts are at the same place.

thanks kobi. It is. I'm doing something wrong.

choppir,

he means, when you create the proxies. both objects centers have to be at the same place !

[3dkobi]

Yeah, it really seems as if the axis center of the legs are not at same place as the axis center of the seat.
Try put both axises at 0,0,0 (of the original chair of course...)

[jenrii]

Would somebody be willing to give a couple tips as to how they got their UV mapping working again after using Proxies?

I have an object mapped out, all axises at 0,0,0, have ran reset system, but the UV texture still flips 180.

Someone previously mentioned that they had 'fixed it manually', but I'm unsure as to what that entails. :)

Appreciated!

EDIT:: Vertically inverting the texture is the key! :) Got it working--
