Different texture space in the same mesh? I'm using 2 different textures on the same mesh. The first looks right with a texture space of 10x10x10 on the mesh, while the second needs a texture space of 100x100x100 to look right. Can I assign different texture spaces to different parts of the same mesh?

I don't want to modify the material because it is used on other objects as well and I would prefer not to separate the mesh into two meshes unless there is no other way.
Unless I'm mistaken, the texture space is an attribute of the texture, not the material, so if you have two materials with different textures, each texture will have its own texture space; if you have two materials that use the same texture, both materials will have the same texture space. So, you can have two different texture spaces, but they need to be assigned to different materials, although the two materials themselves can be identical (except for the material name), one for each texture.
