I've got a single mesh with 2 materials (surfaces). I want to be able to entitytexture only one of the surfaces... how do I?

It's a pain but PaintSurface().

You need to give each surface a unique ID in your modeling package. Then use the FindChild function in blitz to identify the surface.

Example.
Surface1 = "SURF1"
Surface2 = "SURF2"

tex = LoadTexture("mytex.bmp")
mymesh = LoadMesh("mymesh.b3d")
surf1 = FindChild(mymesh,"SURF1")
surf2 = FindChild(mymesh,"SURF2")
EntityTexture surf2,tex
EntityAlpha surf1,0.5 ; for example

Flynn, EntityTexture works on entire entities, not individual surfaces - well, the one I have does, anyway. :P

As MasterBeaker says, just create a brush with the required texture and then PaintSurface().

Cheers guys.

Got one surface for a head and another for the body, want to animate the face texture.
