I have a problem with editing custom properties of mesh, which I import from a FBX, which comes from Blender. When I add a custom properties to an object (for example default blender float), then I export the object into FBX and import ti back, I get an error message when I wanna edit, add or remove the property.
The not working FBX object contains this code, which is probably causing the problem...working object looks the same but without this code:
"_RNA_UI", "KString", "", "U", "<bpy id prop: owner="OBBox001.001", name="_RNA_UI", address=0x000001CB54A9C008>"
It is the same in 2.79.4 and 2.8 Beta
Thank you guys!!
