Hello there,
When enabling MP in Corona MP manager and then disabling it will cause the MP render to be inconsistent and rendered with color profile and color management is applied.
This is problematic as Cinema uses this information to save renders.
Steps to repro (assuming C4d defaults):
1.) Create new scene
2.) Add cube
2.) Add sky
3.) Set Corona as renderer
3.) Render to PV
--
4.) Open Corona MP manager
5.) Switch on MP (in C4D's "Save" section in render settings, MP save options become available)
6.) Switch off MP (note that the above mentioned MP save options are still enabled)
7.) Render again
8.) Go into PV and disable "Show color profile"
9.) Compare renderings.
I assumed that, when MP is disabled, the rendering is again treatened as linear or not color managed at all. (Like it is the case with standard C4D settings, they are synched)
