In my current WIP the Conifer 2 that was imported with the other PG provided conifers has some incorrectly assigned materials. When I correct it and save, it remains as corrected for the current session, but when I close Unity and come back the materials are borked again. Specifically the bark.
Is there a way to correct this without having the speedtree modeler? What am I missing? I don't remember having this problem on the other courses...
EDIT: I still don't know what happened with this one conifer, but I did find a fix. I copied the Conifer 2 materials folder from on of my other courses and pasted into my current WIP. It seems to have worked. I share in hopes that maybe this will help someone else.
