| Summary | 0000999: mipmaps (glGenerateMipmapEXT) broken on ATI hardware | ||||
| Description | what the summary says. attached patch fixes it - when AtiHacks config var is true, don't try using glGenerateMipmapEXT, use glTexImage2D and friends. (don't have svn installed on the new box yet ;p) | ||||

There is a similar issue with nvidias and glGenerateMipmapEXT, so it shouldn't be used in general _to create texture mipmaps_. But it should work fine for FBO textures ;) (will fix it after I collected some more infos) |
|
|
I'll apply the workaround patch while your fix is cooking. |
|
|
this also happens for nvidia, so the currently committed "fix" requires "tuning" ;p |
|
|
Has the better fix finished cooking yet? :P |
|
|
It's already in the repro: glTexImage2D(target, 0, internalFormat, width, height, 0, format, type, data); if (gu->atiHacks) { glEnable(target); glGenerateMipmapEXT(target); glDisable(target); }else{ glGenerateMipmapEXT(target); } (ati got a bug that the texture target needs to be enabled when you want to use glGenerateMipmapEXT, and nvidia fixed their drivers) |
