Rendering commands

[Rover]

Hello everybody

 

When I open a terrain_DATA.INI, usually I see this lines writen:

 

TEXTURE_MODULATE_DIFFUSE

 

and

 

TEXTURE_BLEND_TEXTURE_ALPHA

 

That commands are used for the differents terrain textures. So... I wish to know if anybody knows how affect this commands to the terrain and if there are more rendering commands.

 

Thank you very much!!!
