Re: Normal maps and particles

Sure. I'm mostly thinking about sprites but it's not like XSI has tons of different particle primitives.
I could be wrong but my experience with other softwares suggests that XSI should be capable of that kind of thing.
Shouldn't it?

but then the surface generated would be dependant upon application. Water, cloud .... whatever, not on the particle point set itself. How do you generate normals for points in space, there's no reference.

So why wouldn't they be treated as normal surfaces? It seems to me that it'd solve a lot of shading issues.
I too vote for bump & displacement.
