Actually, I have some more questions about using stencil buffer: - how can I clear stencil buffer on render bin? (in OpenGL tutorials everyone uses glClear(GL_STENCIL_BUFFER_BIT) - is it possible to disable stencil buffer at the begining of the render bin and enable it at the end? Or should I disable usage of the stencil buffer on previous render bin and enable it on next?
