What is the easiest way to do this if there is no addon? Or is there an addon that helps with this? Thanks
Are you looking for this;
- Go in edit mode
- Deselect all (double a)
- In menu on top bar in 3D view: select > Seletct all by Trait: Interior Faces.
- Then press x or Del to delete the interior faces (they are selected).
(My MOAS-GEN is using it in combination of joinging meshes).
You can also see it in part two of my video about Mesh Materializer, and that part is about troubleshooting bad meshes.
Robert that is exactly what I was looking for. Thank you.
