Texturing

[yasar11732]

You don't need any dds files, they are just image extensions like jpg, png or tga, whatever you used for your textures will do. As far as I know, naming of the textures doesn't matter, as long as you exported your dae correctly. If your model view/editor can't find your textures, open dae file with notepad or something, and see where it is looking for textures.

Naming of the specular, normal or other maps also doesn't matter, you create a .mat file with material editor and tell it where to find specular, normal, alpha etc. map.

@DRedshot:

Normal maps indicates the angle of surface in each point of the texture, so that you can have 3d effect without making your model more complicated. There are some photoshop/gimp plugins that make normal maps using bump/height maps.

Edit add:

@DRedshot:

Gimp needs a plugin for that too.
