A GL_ERROR is generated when using GL_LUMINANCE for both format and internal format…
Is there a cause?
I even try with GL_LUMINANCE_ALPHA (both for iformat and format) and it work fine… The GL manual says that the iformat and format should be the same… what would explain the GL_INVALID_ENUM?
Do you experience this problem when using VFrame, or does this only happen on your target platform/s?
Which graphics API are you using?
Using GL_LUMINANCE for the format and internal format should be fine.
VFrame, not the target platform (iPhone)
Any workaround to avoid that it generate a GL_ERROR?
Are you using the most recent SDK that is available from our download page?
I’ve tested this with OGLES 1.1 and 2.0 using a recent 2.6 build of VFrame and it is working correctly.

>> Well try it again cuz I can guarantee you that its not working… I have a wrapper that debug every gl call, and a GL_ERROR pop only on that one…
Honestly 1 GL_ERROR on that specific case doesn’t really bother me that much what really bothers me is glBlendEquationOES that is not working:
