Post Rug Creation.

[InTheCity]

Simple camera projecting and compositing to use Cinemas hair module
after the VRay rendering is complete.

Why? Because hair as an object can kill your scene with millions of unwanted poly's.

I apologize if it seems rushed.

Here's a script to erase all x marked texture tags.
Just add to script manager and run.


op = doc->GetFirstObject();
while (op)
{
var tag = op->GetFirstTag();
while (tag)
{
var rtag = tag;
tag = tag->GetNext();
if (rtag->IsInstanceOf(Ttexture))
{
var mat = rtag#TEXTURETAG_MATERIAL;
if (!mat || !mat->GetDocument())
{
doc->AddUndo(UNDO_DELETE, rtag);
rtag->Remove();
}
}
}

if (op->GetDown()) op = op->GetDown();
else
{
while (!op->GetNext() && op->GetUp()) op = op->GetUp();
op = op->GetNext();
}
}
EventAdd();

As a side note and you may run into this problem.

If you have some reflective objects in the scene that needed to pick up
the rug in their reflection - You can do the following;

Don't calculate it's reflection in VRay.

Pull the object in question from the Null.

Duplicate your 'projection material' -
Apply it as 'Camera projection' again (same method as before)
But this time add the necessary glossy reflections to that single material.

This won't always work, because behind your camera exists some very
bizarre mapping (Take a look in editor mode).
There are even additional work around's for this should it happen.
(Rendering a separate vray shot for the background/mapping to a plane)
Mostly for subtle objects, this method will work quite well.

and just for kicks... (not a rug)

it's a great technique I'm sure...

...but it doesn't look anything like a rug.

IMHO.

Dude, it's very common for people to want dying patches of grass in their living rooms, you shouldn't be so quick to judge.

I wasn't quick to judge...I took my time...

And on reflection. Still looks nothing like a rug!

I just bought a new string trimmer. Want to borrow it? On second thought, the kitties would love this! :D

Thanks for posting this, the flokati look has been eluding me!

Here's a general purpose Shag rug that works well enough.
Scaled according to VRay settings also.

InTheCity, thanks for generously giving your time to put this tutorial together. Text, pics and even a script! Very nice. Also, thanks for not being vague or leaving out key steps/information. (On the last point, I am giving you 4 1/2 stars. I would give you 5 but I am not advanced enough with cg/vray to know perfection.)

[glass.use]

thank you very much for the time doing this.
i also love the rug file you posted 8)

[InTheCity]

The script (and I apologize for not stating the source earlier)
was created by 'Per-Anders Edwards' from CG-Talk.

If I only I could write code..... :(

thank you very much .. :)

just to let you know, you can also achieve the same effect using the actual hair polygons themselves too, and by that i mean have the hair render in vray. The "secret" is to go into the "Generate" tab of the hair object's attributes, and the "Type" attribute to something other than none.
Typically i find for a nice looking carpet feel i go for the triangle type, and for grass, i use Flat. Not only does flat speed it up anyway, but it accentuates the whole "blades of grass" concept anyway.

If you have a slow single-core like me though, make sure to change your settings in the "editor" tab of the hair object's attributes as well.

eg:

soz for the overly large resolution

So True :shock:

Thanks for your effort InTheCity this is very useful interesting way of mixing methods

This is very useful Thanks a lot MrElusive


Thanks a Lot :D

Hi guys
http://www.project1media.com/vray/rugs.jpg

[afternooncoffeeboy]

[DV81]

hmmmm what do u mean jpeg -> projection ?

i wander if someone could make a simple file to demonstrate how to project a photoshop file or pattern colours of my choice onto a carpet like the above ?

thanks so much in advance !!!
