Error when scanning recast graph

Installation
#1

I think it’s caused by a gameobject I have which uses Cloth renderer and has MeshFilter+SkinnedMeshRenderer on it.

Suggested fix (inserted after line: 379 in RecastMeshGatherer.cs):

if(rend == null)
					{
						Debug.LogWarning("MeshFilter " + filter.name + " did not have a MeshRenderer attached");
						continue;
					}

Errors:

There was an error generating the graphs:
