Billboard casting shadows problem
Hi
I am using a billboard for a tree and using the regular alpha chammel technique for the transparency but no matter what I did - the plane still casts shadows upon an object which is behind the plane. This is inside Mental Ray - Does anyone have a clue ? NIR |

can't say I've used Mental Ray, but usually using raytrace shadows works for that. not sure if MR does it differently.

I am not sure it is a bug but I tried every trick I know and some others and still. Fimnally I had to put the tree as a post process in PS.
Thanks |

This is the image, unless the client requests a cange it will be the final one.

Still couldn't find out the solution in MR but in Maya Software Renderer it is corrected by using a zero value in Shadow Attenuation (Shader Raytracing Options)
This is a crucial issue for me ! NIR :-( |
