"This actually leads me to my second question... Is there a good tutorial on multitexuring which is specific to the way you can apply it in Blitz3D on terrains?
I would like to use multilayered tilable textures that are selectively shown using alpha maps. After nearly 1 year of fiddling, I still cannot figure out how this is properly done in Blitz3D."
As for this... You don't want to do that. You could for example, overlay a particular section of a terrain using a second texture layer that has an alpha map. However, doing so would mean the ENTIRE rest of the terrain would have twolayers of textures on it... even if it doesn't look like there are. On top of that, only high end cards can do more than two texture layers at once. So other cards would have to render the terrain multiple times.
Finally, Blitz terrains are slower than the equivalent 3D model. That, combined with their poor texturing, makes them unsuitable for doing a real game. Use meshes. I'm 90% certain you can get just as good results as you see there, in Blitz.
