Hi everybody! First of all, NeHe and crew, thank you for your great tutorials!!! Although i have learned a lot from your tutorials I now have a situation i cannot find the right solution for:( It's about rendering a Half-Life bsp file. I have most of the rendering working and it works great! I got it working with the code from botman by my side, it taught me a lot! But there is a small uglyness in the code from botman and I can't get it fixed either. It's this: In the Half-Life bsp file there is a lighmap texture for every face in de file. Rendering such a lightmap is easy, first you render a face with it's regular texture without using blending, and after that you re-render the face with it's lightmap and use the following blen function: glBlendFunc(GL_ZERO, GL_SRC_COLOR); For every texture that doesn't use color transparency this works, but when I render a face which has some transparent parts the shading of the lightmap also covers the transparent parts. Its really ugly! you can find an image with an example here: http://www.saaltink.net/img/blendproblem.jpg My question now is: is there a blend function to fix this? greetings from Holland Wouter Saaltink

Hmm, ofcourse, didn't think of that, but must say that I haven't used shaders yet.

Thanks for the your answer and the website! I am on it!
