Constant Transparency Issue with intersecting Particles

[manuelriedl]

Hi everyone,
I don't know if anyone has had the issue before, but when I apply a constant/phong/lambertian shading for a point cloud, the transparency doesn't work for intersecting particles.. The particle shape/size, etc. does not make a difference, but somehow the architectural shader seems to interpret it correctly.

I am using Softimage 2013

Cheers,
Manuel

you need to put the shader on the geo that you are instancing not the point cloud.

Or it might be you don't have high enough secondary ray in your MR setting.
