Okay I made a minimum requirements SWEP, viewmodel from a playermodel, just removed the mesh except arms
The problem I have now (and that also is the original problem) is that the SWEP will have whatever Y position i have in my 3D modeler software, as opposed to setting it based off of the QC
I feel like I’m missing some important line in the QC that aligns the correct Y position

Here’s my rig setup:

Here’s my QC
