Particle textures

[legacy-SmokeRingHalo]

Everytime I try to compile a combiner or shader for a particle texture I get a "bad cast" error.
In particular, a TexEnv with a cubemap /celshading.
My explosion mesh spawns withany regular texture but when i try use a combiner to celshade it - it will not compile.
So the question is....Is this even possible?

No.

var (Texture)   texture    Texture;
