We've established that if we use OpenGL (GL, Glew, SDL, GLSL) independently of Cinema 4D, there is a clash between the two. We demonstrated that the clash only exists when OpenGL is enabled for Cinema 4D's editor view but does not happen when in Software mode. Is there any way to lock/unlock buffers etc. for exclusive use of the buffer temporarily?Thanks,

Do you want to draw independently with OpenGL in Cinema's editor view?

We want to draw into a TextureBuffer and extract that (using glReadPixels, which does work) for a material preview. Currently, we are drawing into a FrameBuffer with an SDL window (which will hopefully not be required for drawing into the other buffer). It definitely appears that we are stepping on C4D's toes when we do our OpenGL with C4D trying to do its OpenGL also.
