quoted from the documents on textureblending:
Sets the blending mode for a texture.
The texture blend mode determines how the texture will blend with the texture or polygon which is 'below' it. Texture 0 will blend with the polygons of the entity it is applied to. Texture 1 will blend with texture 0. Texture 2 will blend with texture 1. And so on.
Texture blending in Blitz effectively takes the highest order texture (the one with the highest index) and it blends with the texture below it, then that result to the texture directly below again, and so on until texture 0 which is blended with the polygons of the entity it is applied to and thus the world, depending on the EntityBlend of the object.
Each of the blend modes are identical to their EntityBlend counterparts.
In the case of multitexturing (more than one texture applied to an entity), it is not recommended you blend textures that have been loaded with the alpha flag, as this can cause unpredictable results on a variety of different graphics cards.
