By inspecting some FBX files, I found the following:
- Value of FBXHeaderExtension.Creator in exported files is always "FBX SDK/FBX Plugins version 2020.0.1" whichever FBX SDK version I choose.
- Some versions of FBX Plugin produce FBX file which contains an attribute named "Alpha" as user data. It also contains Cd attribute of 4 channels.
- Unity works well with FBX files that contain the user data.
The issue is the first one. Selecting an FBX Plugin version may not work correctly.
Is this simply a bug? or Do I need to do some additional process e.g. installing another version of FBX plugin separately?
I'm using Houdini Indie ver. 19.5.493, on Windows 10.
