Another issue I experience is a color shift in my colorcorrection node. The HUE shifts from 0.9 to another value making my material blue.
It happens after I apply it from my material library to the Material Editor.
Hi mbetke,
Thank you for reporting this issue.
Currently, the use of material libraries do not provide correct conversion from older version..
The .mat file do not contain Octane version information, so the converter only consider the current scene version..
For the Hue version 2022.1.1 and older, the value was in the range -1 to +1. In 2023.1, this has changed to -180 / +180, so the conversion is to multiply the old value by 180. You might have saved the material library after this conversion, with a 2023.1 version, but when loading an old scene, and opening the library, it convert it again, resulting in values over 1000..
Note that there must be several other issues when loading even older .mat files, as none of the fixes / updates can be applied ..
I don't see a good work around for the moment, apart manually converting libraries.. that would be like:
-re-install a previous version of the plugin
-create a scene, open your libraries, assign each material to the scene / material editor,
-save the scene
-install the plugin v2023.1 Beta 3 - 14.01
-load the scene, re-create a new version of the libraries from the scene materials
I'll try to find a good solution for the next release.
Thanks
