I’m trying to create a rig for a character using rigify. After creating the rig and applying automatic weights, it weight paints in a weird way that I have never seen before:
Okay, so from what I can see, your model has a negative scale on it. When I applied the scale, temporarily turned off your outline modifier (clicking the tv looking icon), and turned on face orientation, your normals were flipped. Flipped normals can cause the weighting weirdness that you’re seeing. I recalculated the normals, reautoweighted, then turned the outline modifier back on (I changed the numbers a bit to account for the new scale of the model), and it all seems to work.
Thank you! Worked like a charm, weights applied normally. I didn’t think normals would be an issue (I didn’t even know why they were flipped in the first place)
