[solved] How to skip tone mapping?

Ok, all good works fine.

But how do you make the Direct Visibility Override 255 white?
At this moment there is no option to skip tonemaping

CoronaOutput = CoronaToneMapControl (!)

Plug white CoronaColor into it, disable all three checkboxes and there you are.

Good Luck

Yes, Corona Output has been split into Corona Tonemap Control and Corona Color Correct. If you would like to use both features, you will have to use those two nodes.
