I've been reading this forum for quite a while and it's only here it seems people respond to shave and a haircut.
Using Maya 2009, Shave and a haircut's Mental Ray hair primitives:
I have 2 issues that I've been trying to sort out:
1) Self-Shadowing and Geometry shadow seems to have no effect when I'm using Hair Primitives.
Here are the settings I'm using:
I have 3 spotlights illuminating Fur. I added Key Light to shave->shadow attributes->Add to selected lights. So the shadow reads fine on the background plane.
On my spotlight I have:
- Depth Map Shadows turned on
- In MR shadow map - detailed Shadow Map
- resolution 512
- samples 40
- softness 0.04
in Render Globals:
- No Final gather or Raytracing
And it all seems to work fine, however attributes in Shave such as self-shadow and geo-shadow don't work anymore which results in a quite a flat image. When I turn to Buffer mode, it seems to work fine though.
Does anyone know solution to this problem?
2) I am trying to sort out a render pass system.
This is easy in Buffer Mode - but unsuported in mental ray hair primitives.
I need to:
output the character mesh + output the hair with a hold out of the character.
As this is hair/fur (a LOT of hair/fur)I am trying to avoid a Render Layer (ie: render everything twice) scenario.
I notice 2 undocumented shaders that look suspicious...and can't find the info anywhere, even the shave site:
Can any one help here ?
Thank you so much!
