Counterpart of RenderTexture.DiscardContents() for framebuffer?

Unity Engine
1

Hi,

This is called Framebuffer Invalidation (glInvalidateFramebuffer()) in OpenGL ES. While we can do this for RenderTexture, can we do it for the system provided framebuffer?

I managed to reduce the warnings of “RenderTexture color surface was not cleared/discarded” to 1 by

  • Insert DiscardContents() for target RenderTexture before Blit().
  • All cameras clear color.
    , but I can’t go further to remove that 1 warning.

Thanks!

Made it with RenderTexture.active.
