RenderTextures do not include Canvas (UI) elements



How to reproduce:
1. Open the attached project
2. Open and play Main scene
3. Notice that where was white screen, screenshot appeared
4. Screenshot (which is done using RenderTexture) should include "MushroomCloud" (UI element), not only the sphere underneath

Happens when Canvas render mode set to Screen Space - Overlay. Screen Space - Camera can be be used instead as a workaround.

By Design: Screen Space-Overlay shouldn't show in render textures at the moment

    I ,as a normie, also like to have DoF and motion blur on my ui element, which doesn't actually need DoF and motion blur

    So since this is By Design, then what are some methods for us to handle creating UI That Fills the Camera Space But Also shows above everything else?

    Had to do this by manually rendering the UI camera to a RenderTexture with an equivalent of the following code:

    m_UICamera.renderTexture = m_RenderTexture;
    m_UICamera.RenderTexture = null;

    For our implementation - periodically taking a snapshot of the UI to be mapped to an object in the scene, this works. But really this should be easier to do than it currently is, and this method would be pretty horrible for continuous rendering. Use at your own risk.

    I have noticed these oddities in the Editor, too, but on my build platforms (Android + iOS) everything worked just fine.

    Without fixing this there doesn't appear to be any way to render the UI both to the screen and to a render texture, since setting the canvas to Screen Space - Camera (for the render texture camera) makes the UI only visible on the render texture.

    Still an issue with 5.3.3
    Setting the canvas to "world space" works, but not when set to "screen space - overlay or camera".
