Fast forward to this year, and I am trying to get physically based measurement from LuxCoreRender .....
1) I dont need the mulitpliers I used previously, as the lights can now be set in watts, candelas, or lumens.
2) I can find a section where I can use a false colour tonemapper.
My questions are ...
1) How to I set the colours, banding and scales of the false colour tonemapper?
2) How may I make a physically based light measurement that falls on the target in for example watts per square meter?
I have most likely missed a tutorial and/or missed a section in blender; maybe I am not running the correct software even

Thank you.
