I was pondering today if this is where that freaking "var my_matrix[16];" thing coupled with the "matrix matMtl" would come in handy here. I decided to install MSVC 6 and get linked to the lib last night just in case it is needed. Good luck!!! You tread deep waters! http://steempipe.blogspot.com

Well, I look forward to screenshots in the near future!!! @ChrispiZ : Code will show up for the grabbing soon. @A.Russell : The water code is posted in a different thread. You should be able to take what you need, discard the rest. http://steempipe.blogspot.com

Assuming this is a realtime shot from the game, how in the world would you get that many shiny areas over such a wide area?
