Short description of error
Create three connected vertices in the object and add the Multiresolution modifier. By increasing the number of subdivisions, Blender falls. If we extrude polygons and add a subdivision everything works correctly.
Exact steps for others to reproduce the error
- Create an object from three connected vertices
- Add the Multiresolution modifier to the object
- I increase the number of subdivisions (although I checked in Blender 2.82 this action is blocked and Blender does not crash).
- Blender crashes without error message.
The problem is solved in prohibiting the increase of the unit if the object does not have solid polygons.
There is no such error in Blender 2.82.
