Materiel Warping on Figure

Porphyrogenitus

Hi - I've actually been having this problem for years but last time I asked about it nobody knew why and they suggested it wasn't happening to anyone else & couldn't figure out why it was happening or how to fix it (I say this not as a slight because I've gotten good help here on other things), so I simply worked around it when I couldn't troubleshoot it. I figured it was my machine or something.

However now I've had it across 3 machines (with fresh installs on each) and four characters (V4.2, G1, G2, and G3 essentials).

What happens is illustrated in the attached picture, which is actually 2 clothing items. Both are on G2F. For sake of avoiding questions about 3rd party content, both items are from DAZ - the foreground black-and white is "After School 2 Genesis 2 Female" top, with smoothing modifier applied. When the arm is close enough to the chest, it warps around the arm, "grabbing" it.

The red in the background is the pantaloons from the Gen X Dress, fitted to G2F but without smoothing modifier applied. It "binds" to the upper thigh and the materiel stretches out in a distorted way.

I've had the problem with a variety of wardrobe items on a variety of characters. I've worked around it by adjusting posing, but it's limiting my ability to, for example, put hands near hips at times because the wardrobe will want to "grab" the fingers (like tentacles).

Is there any way to solve this?

Thanks in advance for any help.
