Redstone Repeater torches turn into wall redstone torches after Mesh Swap
Did the issue happen after restarting Blender?
- [X] Yes, the issue indeed continued after restarting Blender
Check known issues
- [X] I have checked known issues, and my problem is different
What happened?
With Redstone repeaters the redstone torches within them when Mesh Swapped makes them look like redstone torches on a wall.
Before:
After:

What steps are needed to produce the bug?
- place repeaters in a schematic to mineways
- prep the materials
- Mesh swap the object
What version of MCprep are you using?
MCprep 3.4.1
What version of Blender are you using?
3.1.2 also tried 3.3.1
Was it a schematic or a world file? If the former, then it may be a conversion issue
It was a world file, I was initially going to use a schematic from World-edit but I figured pulling the area from world with Mineways was easier. I converted it with Mineways to an Obj file and imported with MCPrep
Have you tried using something like jmc2ob? It tends to have less of these issues
Ok I tried that though it seems to have done worse lol
Before (with JMC2OBJ export):
After Mesh Swap:
After Mesh Swap (without moving the orgin to mass and also if I set the offset in jmc2obj to center):

The source issue with jmc2obj in this scenario I think is actually due to mesh optimization being on, for Meshswap to work, all vertices in the original mesh need to be there and not be cleaned up. It's a toggle option inside jmc2obj. Give that a go if you can.
Ok so that fixed the weird redstone lamps being one, so now its only the redstone repeaters being slanted
