View Full Version : glGenerateMipmapEXT and GL_GENERATE_MIPMAP with PBO

08-26-2007, 10:53 PM
I am not sure if I have a bug or doing something wrong, but here I go...

If I use the GL_GENERATE_MIPMAP method to make mimaps, my particle textures are fine regardless if I use compression formats or uncompressed, if I use glGenerateMipmapEXT() and no compression some of the particles show lines in the texures and if I use compression they disappear? I haven't tried this without using the PBO to stream the data in, but doubt that would make a difference seeing how it works with GL_GENERATE_MIPMAP so the code is sane. This is on Vista and GF8800GTS with latest drivers.

I have't filed one before do you just email them? Or is there a form to fill out? And do you get any response back from them on the issue whether or not it is a bug?

Thanks Korval
