How to synchronize changes made in Cheetah with Unity?

Unity Engine
1

I exported an object to fbx file under Asset from C3D.

When I made changes in C3D, export and replace existing file under Asset.

Also, click reimport in unity.

But, it does not update. How should I do it?

it should automatically update unless you disconnected it somehow or something messes up the file date

normally you don’t even need to export fbx. unity can pick up cheetah3d files directly and auto convert them

I just found it the tubejas-membrane.mat file did not update with the jas file. The datetime is different. But, I did see the color change in cheetah3d.

Do I need to save other thing besides saving the jas file? (if no need export)
