Looks kinda cool doesn't it?
I just finished coding the ability to select new textures for the materials
Here I selected a new texture for the material selected in the materials treeview (cfg#TXRStructuri). Here's how it works:
In the materials tab in the materials treeview the only thing you can select (currently) is Texture. If that node is checked and you double click it then you get to select new texture for it. If it is not checked and you double click it it will show you the current texture (via a render texture window - just like the meshes when you double click the materials for them).
Just a few more things to do with it then a new test version will be available
