There's a Mesh between my legs!

What are we doing to solve the issue, in certain clothing- that when you spread a characters legs, the dress, skirt or pant smears between the legs, like the mesh stretches and gets warped?

Turning Smoothing On makes the area explode. I tried the new Mesh grabber and it pulled the smear, but didn't get the clothing to slide away from the body.

I usually fix this in post or choose another camera angle or outfit, even.

    This is something of a limitation with conforming clothing in general. It can be reduced with good weightmapping, but ultimately, weightmapping works by stretching and warping the mesh to follow the pose rather than by following the laws of physics.

    If the clothing supports Dforce, that's obviously the best approach.

    Otherwise... well, ideally report it to CS and the artist will be able to fix it, but otherwise it may take some repainting of weight maps, or exporting to an editor like Blender to adjust the mesh more precisely than is practical with the interface in DS (even with the Mesh Grabber).

    For me, smoothing only causes it to explode if using Base Shape Matching (the default). If I change the smoothing type to Generic, it looks decent.

    One of the many reasons I hate none dforce (or VWDed) clothing.

    Best way of fixing it, I've found, is to simulate it, either Dforce, VWD or one of the alternatives. I find raising shoulders and arms has a similar effect to what you describe, although probably not as much.

    Could try making little morphs ;-)

    Thanks for the suggestions. This isn't a day for experimentation and troubleshooting.

    Going to try a few quick options and see what I get.....

    Hmmm...I see he's got one for G3 too!

    Wow. How the heck did you find this?????

    ANNNDdd that vendor some has cool other props.

    I will be wishlisting them and waiting on sale notifications.

    Well done, sir.

    OK, here is what you do.

    Look up the parameters tab of the clothing item. Make sure to check the box "Shoe Hidden Properties". When the pose is applied, go into the parameters, click currently used, and look for something like 'pJCMThighSide' in those parameters. When you find it, dial it back down to zero.

    This might help some, but a more permanent fix is to weight map this spot on the clothes. You can also do both.

    Under Tools you will find the Node Weight Map Brush. Click it. You will also need the Tool Settings tab. Go back to the clothing item in the Scene tab, and click on it into you get to the Pelvis bone. With the Pelvis bone of the clothing highlighted in the scene tab, go to the Tools tab and click General Weights to highlight it. 

    Once you do that, you should see the pelvis turn several colors of blue, orange and red. Go to the area between the legs and use the brush to paint it as red as possible.

    FYI, you can have your leg spreading pose applied during this whole process. If you do, you can see as you paint that the clothing item will begin to change shape, hopefully for the better. The weight map effects how much the bone is effected by the pose.

    Once you are done and happy, save the clothing as a either a new clothing prop, or overwrite the original. It may be better to save a new clothing prop with a slightly different name if you are concerned about screwing it up. That way you would have both before and after options. If this is a piece of clothing autofitted from a previous Genesis, then you will want to save this as a new item.

    All in all, this only takes a couple of minutes, and this can mostly fix the problem for all future scenes with the newly saved clothing. This combined with the JCM dial should be enough most of the time, depending on what you are trying to fix.

    If it's something I really wanted to use I would just apply Dforce to it.

    Hey, thanks for this mini-tutorial. I'll give that a try since I've been complaining about this very problem for years. I do prefer dForce clothing now but many of the tighter fitiing pants don't have dForce and I'm not very good (yet) at figuring out the right settings. In the past, I've gone the route of making morphs in Blender but that can be restrictive to the particular pose I exported when I created the morph.

    Oh, and I assume you mean we should save as Support Asset > Figure/Prop Asset?

    I know, this is crazy. I gotta do some copy and paste for my Daz tips and tricks archive.
