Softbody Surface blueprint seems to fail at generation - Snail921 - 10-08-2021
Hi,
When I try to generate and edit a softbody surface blueprint by following the procedure explained here, obi seems to fail to generate valid data for the softbody surface blueprint.
I feed my mesh to a newly created blueprint and hit generate. Right after the generation, nothing happens but when I hit edit button, I get an error as bellow.
Quote:NullReferenceException: Object reference not set to an instance of an objectThe mesh is a relatively simple mesh with 1138verts. which has been created for this experimental purpose and ported from blender.

The mesh's Read/Write setting has been checked on when it was imported to Unity.
Do you have any idea what is causing this issue?

Another user had a similar error:
http://obi.virtualmethodstudio.com/forum/thread-2873.html?highlight=Obi.ObiActorBlueprintEditor.OnSceneGUI
Line 314 in the blueprint inspector accesses the "currentProperty" variable which, if correctly initialized by Unity, should never be null.
After a long investigation it boiled down to a Unity bug, that does not initialize inspector member variables properly. This seems to be triggered by certain window layout configurations. Resetting the editor layout should help, let me know otherwise.

That was it.
Resetting the layout solved the issue.
Thank you so much for the quick and solid help.
