Betreff: primary ray override
Hi,
I want to override a partition with a black constant shader ONLY for
PRIMARY
RAYS. I need to keep
the original object shaders for the SECONDARY RAYS.
My other partition got a reflexion shader to reflect those SECONDARY
RAYS.
Is it possible to use a Ray_type to tell the partition what is the "Eye"
shader and what is the "reflexion" shader.
In fact I just want to do a simple reflexion pass with an opaque alpha
matte
for non reflective object.
What is the best workflow to do this ?
Hi Guillaume,
as I don't know how to solve the Ray_type thingy, I would set up 2
passes : one for the reflection, (1 partition with the visible object
with an override to turn the primary rays off, 1 partition with the
reflection object)
and one for the matte/mask
you can composit them later on...
or am I missing something ?
Lucas
