Model exporting

[WALP]

Hm, that depends. If you're using several diffuse (=color) textures on one model, that won't work. hpl doesn't support multiple materials per mesh as far as I know, you can only have one texture map of every kind. (So, you couldn't for example use one jpg. for one half of the model and another one for the other half.)

If you mean that you have a diffuse, a specular and a normal map, however, they simply go all in the same folder. When you create your .mat file, you'll have the option of adding the normal and spec map to your material there.

It does support multiple materials per model and it has been done many time in original amnesia, fx servant_grunt and zimmerman_ground.
I dont know exacly how it works in maya but I know that to do it in blender you have to seperate the materials between different objects before exporting. HPL2 will then recognise them as submeshes, which are also important when wanting do to a lot of things in the model editor.
