Clothing not fitting as expected after posing

[Jason Weise]

I’ve noticed with a particular scene I am working on that clothing such as bikini bottoms are having an issue with “fitting” after applying a pose to the character.

I have had a look at the morphs in Daz and there are a bunch of JCM’s that appear to be applied to the clothes as well that don’t appear to come across to Blender. When I try to “transfer” the blend shapes from the G8.1 body to the clothing it fails with an error.

The issue seems to be more pronounced in sitting positions where the bikini bottoms disappear into the body in the crotch area (having tested the exact same pose in Daz the bikini bottoms seem to reconform and all is good)

Has anyone experienced anything similar and have a solution? Could it be because the JCM’s are not applied to the clothing (in this case the bikini bottoms) and when posing they don’t deform as expected?

‌

Thanks in advance for any advice you might be able to shoot my way

Could you describe the transfer error. In particular the output in the terminal window.

Hi Thomas

Sure thing the error is as follows:

I am using the Crochet Bikini Bottom and it doesn’t seem to be able to have any corrective morphs come across of be transferred (I even tried Easy Mode).

I have also noticed that the “gens” also poke through in Blender yet fit perfectly behind the bikini bottoms in Daz (with the correct collision settings of course). Is it expected that the bottoms should “conform” exactly as they do in Blender?

Ok so I think I have figured out the “why” to my last comment above:

Daz Studio is recalculating the collisions after posing so reshaping the groin area on the bikini bottoms so they fit properly, this naturally doesn’t happen in Blender.

Has anyone managed to come up with a way to “reconform” tight fitting clothing in Blender after posing so it can closely match to how it fits in Daz without the genital area poke through?

The error about the unimplemented rotation mode has been eliminated, so the shapekeys are now successfully transferred to the clothes. However, I don’t know what the rotation mode does and simply ignore it, so perhaps something is missed. The result in this case looks fine, though.

To avoid that skin pokes through clothes I use the tools in the Visibility section. Add Shrinkwrap probably works best in this case, since it is difficult to create a good mask which covers the area under the bikini but nothing outside.

Another possibility is to create two versions of your character, one nude with genitals and one dressed without, and use different ones in different scenes.
