Hi! Right, thanks for the help!
So I just copied the two scripts from the link you gave me, put the first one under "Editor" folder, and the second bound to the 3D Object.
From here it's working, the Unity console is printing the custom properties once importing the object. (see screeshot in the link at the bottom of the page)
In Blender, I set 3 properties:
- Float_custom with a value of 2
- Int_custom with a value of 3
- String_custom with a value of "MyString" (without commas)
I've been trying to access them with Playmaker, but no success. I've been trying with the built-in "Get Property" action and also by dragging the "User Data Holder" script in Playmaker window.
Here's the package file containing the 3D object + the scripts. (Just in case, I also put the 3D Model and the Blender file in the folder)
Hope I got it right. Tell me if you need anything else.
