Hi Nectarios! We recently debug an osg application that have an issue with textures only in ATI cars. Our problem is that we render the same texture for different geometries and some of them have a texture matrix applied. We debugged our application with gDEBugger and notice that the mipmaps are not recomputed after apply the texture matrix. This old midmaps produce some errors in visualization. To disable hardware mid map generation you can set setUseHardwareMipMapGeneration(false) in your textures. This works fine in our application.
You can use gDEBugger to show your texture mipmaps and detect if the error is there. Cheers, Maria.
