Optimizing Fur Renders
on Aug 25, 2005 at 6:37:17 pm

I have a scene that has a large field of grass that I am using fur to create. The field is pretty large so I have to have the density set up to about 100000 to keep from having that independant blades of grass look. I have set the light model to ambient + diffuse. The renders are still kinda clunky and I was wondering if anyone had any optimization tricks to get the render times down.

I have tried paint effects but since the field is so large the strokes have to cover a lot of space making those renders unmanageable also.

You could try creating a depth map that reduces the density the farther away from the camera the grass gets.

Another thing you could do if you wanted to use paint effects is create a single paintFX patch of grass. then grow particles on your surface and instance the paintFX onto those particles.
