But when importing exr's from corona to fusion, there is a extra gamma applied (1.2?) because the image in fusion is much darker than in VFB. And then you need to specify the float gamma thing to have the same result in vfb and fusion ?
AgX luts for Corona from this thread are made for default Corona behaviour regarding gamma transforms in VFB. by default VFB has hidden 2.2 transform after the
TONE MAPPING stack and effects. it also has hidden gamma transforms in every
LUT operator.
if you are using my AgX luts there is no need for
string option changing VFB's gamma behaviour ("float gamma thing").
