VaM 1.x Need help from clothing experts: Persistent bumps/spikes with morphs (My first clothing asset)

[Bplus]

I really need some expert advice here. I'm currently trying my hand at my very first clothing item (a nipple overlay) and I'm slowly losing my mind.

The Issue:As soon as I load the overlay into VaM and dial up the morphs (specifically breast/nipple morphs), the mesh gets distorted, creating these ugly bumps and spikes. It looks like some vertices are getting completely wrong weights and shooting out in random directions.

What I've tried so far (with no success):

• I built the mesh strictly on an absolute Zero-Morph Genesis 2 Female Base in Blender.
• I did the binding in DAZ Studio using the Transfer Utility (also onto a flat, zero-morph base, Resolution Level: Base).
• I tried keeping the exact original triangle topology from DAZ.
• I completely retopologized it manually into a clean quad mesh and shrinkwrapped it.
• In VaM, Surface Offset and Thickness are set to 0.0.

No matter which workflow I use, these damn spikes remain in the exact same spots on the mesh.

Is this a known limitation of the DAZ Transfer Utility when dealing with skintight overlays? Is there a weight painting trick in Blender or DAZ that I'm missing as a clothing beginner?

I would appreciate any advice you guys can give me. I've attached some screenshots of the issue!
