Sorry for the late reply. Genetica 4 is just astonishing but your texture lab is and excellent piece of software and help me a lot. I encourage you to test the limited version of Genetica 4 on their site http://spiralgraphics.biz/gen2tour/index.htm or see some videos on you tube about their format.
You will love it! Im using your Texture Lab to create textures for the old EA game The sims 1 and its amazing.
