This is the problem: I have a mesh with 2 textures in 2 different "layers", but I have to change the "VertexTexCoords" in only one of those layers! Plese help me!

Every texture has a parameter for determining which set of texture coordinates it uses. Just set that flag when loading the texture or use the TextureCoords command.

In vertextexcoords, their is an optional coordset parameter. to modify your first uv layer, use 0. to modify the second uv layer, use 1.

Mmh! I used

EntityTexture mesh,tex,0,0
EntityTexture mesh,tex2,0,1

VertexTexCoords surf,tria,u,v,w,0

but it changes the coords of both the textures!

Precisely: If I use a coord_set within the range 0 - 0.5 both the textures change, if I use a coord_set greater than 0.5 nothing happens...Why?

"tria" must be the Vertex Index. Other than that I don't know why this should not work. Maybe your Hardware don't supports multiple Textures. Maybe try to turn on Software Multitexturing: HWMultiTex 0 to check this out.

Ok, now it works! I used TextureCoords 0 for the 1st tex and TextureCoords 1 for the 2nd tex, and then it works well! Thanks boys!
