Desc: First of all, i like to say thanks to all for comments, thank you.

And now about results:

You see that rendering time very close, i must say equal. That was big surprise for me, i was thinking that displacement will be faster than polygonal grass, but know i now that i can use grass instead displ.
I rendered every test 3 times and choose the best one, another one thing that I don`t use the same amount of grass in every generator (they make it in different way: Count, Distance between etc., but i tried to make it equal for look.

and the last one, don`t look at render time, take a look at Total Triangels, definitely mine winner : Fust&Fur., but don`t forget that Displacement did not make any extra polygons.

Note: Mine opinion subjective, and can`t be used like argument that generator better or that worse.

If You will have a warning about "no plugin" don`t worry.

displacement looks good
doesnt beat dpit though !

daan

[glass.use]

both are good, since they are test why dont you enable the stamp so we can see the time :oops:
i like the 2nd more.

[ak-vision]

hm, i think the first looks more realistic. The second looks good, but it looks more like the fur of a green bear... :wink:

cheers
Andre

ps. perhaps the grass in germany is not that nice...

[sadece]

Displacement takes too many time to render on my core2duo@2,0 :(

[braalin]

i vote for fast&fur :D

[Rich_Art]

Great examples. I would go for the fast&Fur.
I hope the C4D hair is supported very soon. :)

Peace,
Rich_Art. :wink:

[glass.use]

Love the fast&fur GO Renato!!!
thanks for putting the time Tong :wink:

[Tong]

yea, hair is a big surprise, it`seems it was never created to use like polygons objects, only like Cinema part.

:cry:

or maybe i just don`t know how to cook it :wink:

[glass.use]

why did you put Hair in the vote :lol:

[Tong]

it`s very democratic ;-)

maybe someone can use it, i sure it can be used on 64 bit Windows with some big memory 4+ gb,
but i don`t have it :( so who use it can vote too.

[Sputnik]

I like the colours of the displacement image more then the other ones...
...even if the grass structure is not so good as in the other cases.

I had some tries with displacement grass on myself too..
..the results were not bad but the rendertimes exploded after increasing the GI and displacement quality.
So for now I gave up and will do it in post like before...

Here is one of my test images (posted already in a thread about displacement)

[scanmead]

Displacement looks like grass, Dpit looks like what we wish the grass looked like. Have to go with displacement.

[Tong]

add scene file in first message.

if someone could make image with Hair, it will be really cool.

[Rich_Art]

Wow that looks very cool.

Peace,
Rich_Art. :wink:

[afternooncoffeeboy]

hey tong, is vray fur a special max shader or is it vray? is this shader based on displacement or how does this work?

[Tong]

It`s Vray shader, not Max, no displacement.

VRayFur is a very simple procedural fur plugin. The fur is generated only during render time and is not actually present in the scene.

nice hair, the problem with vray fur i see it more like plastic juggler lol but looks nice.
the big advantage of vrayfur, i think, it built-in vray, and it use vray instance system, so the rendering of it don`t give problem with polygons.

vlado or Renato can correct me if I wrong.

[Tong]

PC ? ;-) and what happened with rock ?

[glass.use]

Intel centrino duo cores2 (2.0mghz) 2gb rams. well the rock disappeared because of the long grass.. its down.

[Longone]

Wow Glass.... That looks nice! :D

@ Tong: Narf!

[scanmead]

The VRay Fur looks great! Sounds like it works a lot like Hair in non-polygonal mode.

You guys have really got some nice grass growing in here. :wink:

:shock:

i vote for VRayFur! the second pic is quite convincing...
thankx for testing everybody.

[machmirdenlukas]

i think the best solution would be proxies with vrayfur combined with displacement. i guess the evermotion-guys do it that way .

my grass wip
i think diplacement works only good for short blades of lawn or carpets in this manner. not perfect till now.
i hope proxies and vrayfur will make it. i think stefan wrote something, that proxies will not be so easy to integrate...

vray fur plugin shader will also come at a time,
but it is a plugin from vlado to vray not in rendercore.

very cool, can you please explain the settings for the grass on the first pic?

[maya69]

Hey, steph i hope a vray for plug in is developpe quikly for vray c4d because i like and i think this really great stuff for archiViz

best regard

philippe

[stefan]

we sure do our best to add all,
first priority was to impleemtn c4d shaders, next step we alraedy work on rebuilding vray to be able to use c4d+vray shaders both, when we have this adding a shader plug like vrayfur is nor problem:-)

cheers

hi tong,
sorry for answering late,
this was a very quick test and i have not saved that particular scene, but i know:
-diffuse layer:psd-file with two tileable grass-maps in blending mode (textures from an evermotion exterior-scene)
-displacement: noise-shader (random) with very low global-setting.
-mapping parameters: 6, -3, keep continuity
-geometry parameters: gobal parameters off, edge length 1.8, max subdiv. 256

far from being perfect...
cheerz and happy holidays. m

[Tong]

I did not asked anything :lol:

[machmirdenlukas]

I did not asked anything :lol:

lol, sorry of course i meant hiro...

[FrederickRM]

I just realized something after seeing the Vray MAX pics that while Tong did a great job with the test, his C4D "grass" is pointed at the top and CUT grass is not. Short, new grass is but we're used to seeing cut grass.

So I'm grabbing the files to play with that idea :shock:

[sketchbook]

hey longone

can you post the textures for your sample scene?

thanks!

[Longone]

hey longone

can you post the textures for your sample scene?

thanks!

Sorry i can't! It's from Evermotion Archmodels 42! I'm pretty sure i can't post their stuff.... :cry:

[sketchbook]

ah ok, no worries.

thanks for the reply!

[**__Alex DJ__**]

Hello my friend, sorry about my english...I'm italian boy.
I have a question:
Vray fur, is only for 3dsm.... Or also for C4D?
And when i found it....
Thanks;)

[glass.use]

Vrayfur is currently not available for c4d, it will in future updates. you can use many replacements as in the first page its much better i guess.

[**__Alex DJ__**]

Thanks.....;)

Hi Longone,

^but can you tell me something about your fast&fur settings ;)

greetings peter

[Shordy]

2,5 million tris and vray works stable :) 170mb RAM was used... Rendered with fixed rate 8, some strange glowing on the right side of the stone :(

the glowing is maybe some specuar?

cheers

Hello:) Could you share this hair scene ?

[exor]

quick test with the real ground plants + paint on surface:

- standard pys sky+pys cam
- 11min rendertime
