Luxcore To Aces Study

Update
You can try Luxcore with Blender 2.93 actually with ocio Thanks a
very kind Blender developer Nyck. Hope he soon get an account on
the forum:
You can download this window build to test :

Old infos
I have been studying recently How Aces Work and possible implementation Inside Blendluxcore.
Since Quite a while now Luxcore already support OCIO wich include ACES (you can view the thread Here :
viewtopic.php?f=5&t=3446)
Since it is also Possible to install ACES profile color management directly inside blender I also decide to give
it a go. For those willing to test here is a tutorial on how to do it : https://youtu.be/B7FWNNDXBl0
here is a lighter ACES Package for quick download : https://github.com/colour-science/OpenC ... s/tag/v1.2
The scene for the test is quite simple and was done to show main difference between Blender Cycles Aces And Luxcore under the same
Blender modified Aces color management.
Here are the result :
Cycles SRGb vs Luxcore SRGb
Cycles ACES vs Luxcore ACES Flat color Sky
First Conclusion : You can see that they look identical ( except that Luxcore is a bit brighter and cleaner due to Gi cache)
So color Input are respected
Cycles ACES vs Luxcore ACES Flat color Sky + textured floor
Cycles ACES vs Luxcore ACES HDRi + textured floor
Second Conclusion : As soon as texture are involved huge difference spike due to the fact that it isn't yet possible to set texture input color space in Blendluxcore even if the core engine support it
So look like we just need this option to specify texture input color space and we are good to go with ACES in Luxcore.
1_Texture input color space
2_Hdri Color space
3_maybe there are some other part for texture input color space but you get the point.
How it look under Cycles :
