Short description of error
I have two scenes, one with a cube in the top left of the camera's view and another scene with a cube in the bottom right of the camera's view. Each scene has a separate render border around that scene's cube. In one of the scenes I have compositing set up to render both scenes and lay them over each other (transparent background is enabled in one of the scenes to allow this). When I render the frame I find that both scenes are rendered using the render border of the current scene instead of taking into account each scene's individual render border, which means the final render appears blank (as the empty area of one scene is overlaid on the other).
This can be fixed, but only by pressing the render button on the render layer node for the scene that rendered incorrectly. When I do that, it uses the correct render border for that scene.
Not sure whether this is a bug or intended, but not what I personally expect.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
- Render the current frame.
- Either by looking at the rendered output of the viewer node via the image editor, or by looking at the render layer thumbnails, you can see only the top left was rendered for both scenes.
- Press the 'render' icon on the render layer that rendered incorrectly (with scene name "Bottom Right") to re-render using the correct border.
