YEs, I Highly Recommend the "Caustic Generator" at the link above. I have been using it not lomg after I got started with 3D in late 2005 and it is an exceptional little app. You don't have to install it, just open the zip file and it will run on any computer and the textures it makes are Seamless. I have it in my thumbdrive!!!

I would rather be Politically Incorrect,
Then have Politically Correct-Incorrectness!!!
