yet another limitation.. 2004-02-26 - By Oz Adi
Back
looks like a mental ray limitation..
I got a transparent glass. (phong) and it has a red opaque sticker on part of
it. (lambert)
I mixed those two, using a mix2colors that is connected to the surface and
shadow of the material,
the phong goes to the base-color, and the lambert goes to color1.. the sticker
's alpha goes to the wheight
to determine where on the surfaces, it's a transparent phong, and where's the
opaque lambert..
the problem is with the shadow it casts on the floor..
If i connect the transparent phong to the Material's shadow, the shadow is
coorect for the glass, it is very light
depending on the thickness of the glass.. but if I connect the mix2color output
to the Material's shadow,
I expect the shadow to be light and transparent where it's phong, and opaque
where it's a lambert material..
but xsi renders all of the shadow opaque...
is this a know bug/limitation? is there a workaround for that?
cheers,
Oz
