Texture a random shape.

you could always do the following, which works perfect for me for creating internal textures and images.

Graphics3D 640,480
setbuffer backbuffer()

Global Mesh=LoadMesh("object name")

Global Texture=createtexture(Size,Size,Flags) ; size being 64,128, 256 etc - and flags is optional, remove if unneeded

setbuffer TextureBuffer(Texture)
Line 10,10,400,10
Line 400,10,400,200
Line 400,200,300,200
Line 300,200,350,150
Line 350,150,10,10
setbuffer backbuffer()

; rest of program

And then assign it to your mesh / object - with EntityTexture Mesh,Texture

Hope this helps ya matey,
