How can I export a multi-texture material?

I was looking in the blender2cal3d script and I noticed it exports the material with an array of texture filenames.
I tried making a material with 2 textures, but it seems to only export the texture that I uvmapped (the arrray size is always 1).

Is it correct, and I can’t export more than one texture? At least the uvmap screen doesn’t let me map more than one texture.

Dunno about the capability of the exporter. But UV in blender is limited to one texture by face. So you can, for example, go in face select mode, select only the faces you want and assign a texture In the UVmap window, then select other faces and assign an other texture. This way you work with multiple texture on the same mesh.
