AEM little bit of progress there.

so now , that i can paint any clean RGB color i can transform it later on to a radom selected texture to attached to that color.
im thinking about 3 kind of textures on each color, meaning a simple grass can come in 3 forms i just hope that it will do the seamless ok , if not there is no way im using super high texutres cause then we will have a major fps drop considering we need
a few alpha blend textures for each terrain or segments and atleast one more for the normal map, if we want a specular we would need another.. at the end AEM wasnt as i planed , as it will still be extremly awesome using random created textures from stamps and even can randomize it again and again each time you enter the level so that could be awesome.
ok im taking a break for now , will continue later on.
matty whats up with Fulcrum ?
Tech whats going on with the computer ?
Hassan whats going on with the Mech animation?
p.s (edit)
here is the seamless code Van B gave me yesterday
