There is bug in color management. Let me explain:
First, I've set in Octane Preferences -> Material -> "Textures: Default Color Space = sRGB".
Some of my custom materials use Color Space: Linear sRGB + legacy Gamma = 2.2.
Newer materials use Color Space: Linear sRGB = 1.0
Both settings look good when working with the materials in my scenes.
But I've experienced a strange and random experience with some materials. When I drag and drop them (using the compact material editor) the color space changes from sRGB to Linear sRGB, resulting in a bright material because the Legacy gamma stays 1.0.
This happened also to bought models like trees from Maxtree. I contacted them, and they created the materials in proper color space. So Octane seems to "convert" something internally.
I wasn't able to track the problem down, but it slows down my work when I have to change the Legacy Gamma or Color space manually. Especially with vegetation.
Any ideas where I can start to solve the issues?
