I’m filling some arbitrary geo shapes volumetric shading. I’ve never had good results with mental rays parti_volume and it’s not any better this time.
It doesn’t look like it’s a true volume.
I applied it to a cube and textured the scatter to test and I would expect to see actual volume inside the cube as if it was a fluid container. The result i get is almost identical to applying a 3d texture to the transparency of a lambert. It’s only visible on the outside edges of the volume.
It’s done the same thing when I tried light rays for another project, but I was able to get away it. Putting the camera inside the volume makes the effect even worse.
