Bored of vertex colors and want to display the real textures?

Part A is for exporting multiple meshes that use the same texture map.
Part B will take you through how to export a function for each selected object.

Note: Debug Color was commented out because it's a diffuse, but you can always uncomment it if you'd like

Analyze:

Be sure to change TEX_WIDTH and TEX_HEIGHT to that values of your texture's dimensions -1.

To convert from floating point textures to fixed point, you do (short int) (n * 127 * (1<<4))

Each function is exported as Draw_model_name().
