There are four textures in a generic armour item. Sometimes there are 3, as an item has no MSK and all the colour is on the BM (For example, Mizora's outfit). Sometimes 4-5, as an item may have a GM (glowmap). | |||

This controls colour strength. It is flat and white or grey, as colours are overlaid on it via the MSK. The shader for the game is quite powerful so many BM are not very detailed. It will be called a BM if it has no transparency, and BMA if it does. The A stands for alpha, as transparency requires an alpha channel. | This controls colour strength.

The physical map is 3 maps in one, combined into one image. Easy to spot, it will be pink, green and blue, or some combination of those colours. | The physical map is 3 maps in one, combined into one image. Easy to spot, it will be pink, green and blue, or some combination of those colours. | ||

Rarely an item may have a GM- a Glowmap, which controls its VFX. This is usually black, with white sections to let the glow through. | Rarely an item may have a GM- a Glowmap, which controls its VFX. This is usually black, with white sections to let the glow through. | ||

This is an Open GL normal map. The inverted green channel turns it from DIRECTX to OPENGL. | |||
You can overlay PBR materials on it if you choose. | |||
Remember to do all these steps in reverse to export the texture in the right format. | |||

== Remember your Mipmaps == | |||
You need mipmaps on anything that could move closer or further away to the camera, the only case you don’t need them is static elements like the UI. Things that don’t have mipmaps tend to have an odd ‘static’ to them, instead of a smooth clean appearance. | |||
''Textures do not export from virtual textures with mipmaps attached!'' Even if you are not editing some maps, you need to import them into GIMP and resave with mipmaps to generate new ones. | |||
It is recommended to use Kaiser filter mipmaps as they are sharper than default mipmaps, but any will work. | |||
