ACEScg Lightwave3D Fusion workflow

[ChrisBrejon (Christophe Brejon)]

Hello there,

a few answers :

@duckfanatic

You’re correct until Lightwave has native support for ACES there is some limitations but now that I have it set up correctly in Fusion using the OCIO color space nodes and using 32 bit linear sRGB renders from LightWave I can still see enhanced benefits.

Awesome ! I’m glad you’re seeing some benefits.

@duckfanatic

What I noticed in Fusion is that when making color corrections etc. usually its best to input the values with the keyboard instead of the slider. The input values don’t have to be that large so the sliders can be over sensitive.

This might come from an incomplete OCIO integration in Fusion. Same thing was happening in Guerilla Render before developers take a real look at its implementation.

@duckfanatic

One thing I do notice is I sometimes lose detail and contrast in the white values on some renders any advice on how to deal with that?

You are probably talking about the rolloff of highlights here which is part of the tonemapping. If you could provide me an example, it would be easier to help you. But general rule of thumb would be (if you were working with a simple sRGB display before ACES) :

• Put more energy in your lights.
• Legacy assets (made with a sRGB display) would probably have to be tweaked/improved.
• If we compare with a plain sRGB display we should normally have much better details with an ACES ODT so I’m a bit surprised by your question.

Regards,
Chris
