Panties and Thighs

Rezzer

Sorry if this is an old post; but I ran into this problem recently and I think I know how to fix this. I'm also relatively new to DAZ, so take that into account as well.

This is what causes the problem:

1. The weight map for the crotch area gets assigned to the left and right thighs. That's why it "sticks" to the thighs when they bend.

2. There are two JCMs in G3F called pJCMThighSide_85_L, and pJCMThighSide_85_R, which further deform the geometry when the thighs are bent to this extreme position.

To fix point 1. You have to use the Node Weight Map Brush (Alt + Shift + W), select the Pelvis bone on the underwear to be fixed, use Symmetry on X axis, and paint the crotch area read completely. This will remove the regular influence from both thighs when they bend -- which already will fix about 80% of the problem because the underwear will no longer stick to the thighs. However, some of the geometry will still look a bit wrong.

To fix point 2 you'll need to export G3F with both thighs bent (just as a guide) and make two custom morphs for your underwear to replace pJCMThighSide_85_L and pJCMThighSide_85_R. If you want to understand the problem, select "Show Hidden Properites" in the Parameters tab and navigate to "Hidden -> Corrective" and set both these JCMs to zero. The geometry should snap back to its original position; but it will also leave a gap and it will probably intersect G3F in some areas.

Making these morphs isn't hard; but you have to remember that the middle symmetry line will get applied *twice* when both legs are bent like this. So, when creating these morphs bear that in mind. In my case, the way I fixed this was by exporting G3F with both thighs fully bent. Then I created a single morph that fixed both thighs at once and then I split this single morph into left and right morphs -- but keeping the influence of the symmetry line to 0.5.

Finally, when importing these morphs back into DAZ you need to use "Morph Loader Pro" and select "Hidden/Correctives" in the "Property Group", "Deltas Only" for "Overwrite Existing" and change the names to be exactly pJCMThighSide_85_L and pJCMThighSide_85_R as needed so that they overwrite these JCMs.

Fixing point 2 requires a couple of custom morphs to be created for the underwear, which is probably not easy to automate. This should explain why it's nearly impossible for any content creator to create a single-click solution to import G2F/V4 content into G3F that will work for all cases.

Anyway, hope this helps.
