Well. Texturing is done after all this time. I find difficult to know what I have to do now that I don't have any texturing to do...
I am now arranging all the 3d and texture files to be exported to the game engine.
Once that is done I will create a material, set up its values and duplicate it for each object replacing the textures. This will ensure that all materials will react to the lighting the same way.
After that, I will replace the untextured and old models in the game and will start making some screenshots. I think that I will be able to make a few video captures by this weekend.
