I have started using blender for a couple of weeks now and I got familiar with the compositing interface. The problem is if I change the color from, lets say, gray to red through compositing it will still render as grey. How do I fix it so that it will composite?
I would check 2 things first:
- Do you have the Compositing checkbox in the Post Processing panel under Render settings checked? If not the render process will bypass the compositor.
- Do you have your compositing nodetree connected to the Composite node? If you only have the Viewer node hooked up you won't see the effects of your composite.
