I’m having an issue with the wireframe modifier in version 2.8 creating random geometry that is not part of the original mesh. This is not the first time I have had this issue. In this case my base mesh has been downloaded from Turbosquid (but originally created with blender), which I have edited, decimated and then cleaned-up. The solid body model and geometry look fine…
But when I apply the wireframe modifier it looks like this…
As you can see there is a lot of craziness going on here that shouldn’t be.
It’s not being caused by rogue vertices and I’ve tried everything I can think of to stop this happening to no avail:
I have applied all transforms, deleted loose vertices, merged by distance to remove doubles, reset normals and UV’s, deleted and reapplied the wireframe modifier and even exported the mesh as an obj and imported it into a new project, but nothing works.
The same issue occurs if you convert the mesh to wireframe using the the setting in the MESH context menu in edit mode rather than applying the wireframe modifier.
The problem only seems to affect certain models, I’ve used the wireframe mod with several similar models from various sources, that have been similarly edited with no problems at all, but this is not the only model I’ve had this issue with.
I’m running Blender 2.81 stable on Mac OSX High Sierra.
Anybody any thoughts on whats going on here, or able to suggest a fix?
