I ran into another problem today thank you for the help so far. I have been follwing this tutorial http://b2cs.delcorp.org/vtut/alphaMappedTerrainPalette.htm
on alpha mapped terrians with blender and have notticed it on some of the downloadable examples, when ever i change the renderloop to terrianfixed or anything the test window is always just black, or the terrian shows up without any of the textures all in grey I know I am most likely missing something but not sure what it is. aso the alpha option seems to be missing. do I need to just scrap my whole install and start over maybe. Any help on all this is greatly appreciated, and if there is a better way to do terrian in blender I am open to the suggestions.
