Excuse me, but should the DLL be in the addon or should I copy to another location?

Pipeliner · December 20, 2019, 4:55pm

@imdjs please collaborate with the devs and improve blender! You will learn how to develop for blender

Mephist0 · December 20, 2019, 4:58pm

Thanks a lot! Import works well, but when an object is imported, it has two users, because of this, you can’t apply a transformation to the object.

fix this problem

Nice! But, Windows only? I can see a dll inside. Do you also have a Linux version?

imdjs · December 17, 2020, 3:12am

I dont have linux OS,no linux version for now.
