Yea thanks sswift. I went to IRC and got heaps of help from our friendly neighbour morduun. He dug up a vertex alpha demo by worldcreator that demonstrated it. But the problem is i already created a huge terrain divided into 20x20 sections in 3d max, and i planned to hold each of the 400 sections as a separate b3d file (or children of 1) and hide/show them to get good fps ingame etc. I did this because i read in blitz that multitexturing is possible for 4 layers, and i glanced over some multitexturing demos and thought it must be easy to apply to premade terrain. Thats where i was wrong. I saw worldcreators terrain demo (kindly uploaded by mordun to his own server since BC is down) and basically each layer has to be a 3d model of its own in a way with vertex alpha specified for each vertex. Doing that for my existing and highly detailed terrain would be impossibly tedious, so i dont think i will do it.
I will either scrap this terrain and make a new one using some sort of editor (doubt it), or use only 2 textures per section to create some variety (more likely).
Oh, and if i wasnt clear enough i need 4 differnt terrain types (forest, rocky, grass, sparse grass) to be tiled as detailed textures on the terain and blend into eachother gradually.
I learned something so it was all good. I'm not working on anything serious, just a learning project.
