FBO frame buffer

Posted Thursday, 19 August, 2010 - 08:04 by Powerino73 in

i have a strange effect with GlClear how you can see it works only around the drawen geometry (the white color is the glclear color). Any ideas?
If i don't draw anything in the rendertarget it seems that glclear doesn't work my screen is always black while if i render something it works fine but doesn't clear the background it seems it doesn't work!!
Any suggestion?

Is the correct FBO bound before calling GL.Clear?

// Clear the fbo
GL.BindFramebuffer(..., fbo);
GL.Clear(ClearBufferMask.ColorBufferBit);
// Clear the screen
GL.BindFramebuffer(..., 0);
GL.Clear(ClearBufferMask.ColorBufferBit);
