Subject: Help with stretching fabric over breasts


crystalmethodcaf ( ) posted Wed, 27 January 2021 at 7:02 AM · edited Fri, 19 April 2024 at 3:39 AM

Does anyone know a way that we can stretch fabric over breasts instead of having it stick to them? I've seen it for G8F via add ons and something called dForce for Daz, but haven't found anything similar for Poser. An example of the look I'm going for is like the Honey IV cami:

It seems like that was built into the figure, but I'm hoping there's a way to adjust this for any top. I'm using the La Femme figure.

Side note: Do G8 characters still not work in Poser 12?

Thanks all!

You can use a magnet to pull the fabric between the breasts out.

Dynamic clothing will fall more realistically, and won't have that "boob sock" look. You can adjust the settings in the cloth room as well, so the garment is less or more clingy.

No DAZ figures after V4 work in Poser 12. DSON is a Python script, and will not run in Poser 12. (They had to go to a new version of Python because the old version reached its end of life.)

I started going down that path but it was pulling pointy parts out of the fabric so I stopped.. I played with it a little bit more and seems like it might do the trick. Any other tips for using magnets you have, feel free to share! Thanks!

That fabric stretch at the breast really needs to be a built-in morph feature. Maybe the morph tool might give you what you want but be prepared to spend quite a bit of time perfecting.

@ranym77: you can bring in the Genesis series models into P12 if you save them back into the Library in P11. I have done it but Genesis 8 is a pain to pose without pose presets. But it can be done. I really need to attempt it on my second computer to verify that it consistently works.

The morph tool is fine if you aren't trying to be fancy, e.g. just to pull the fabric out. Bring down the magnitude (the default is way too high and you will overdo things), use a softer brush, pull a little bit many times instead of a lot once, check your work from multiple angles as you go (the posing camera is usually best here). Sometimes Pull is better than Loosen, move the camera around so you can pull the right direction. Smooth can help too although sometimes you need to fix fit after smoothing. I think the morph tool is pretty good actually, but you do need to get a feel for it. You'll only get that feel by using it. Start with simple tasks and work your way up.

The stretch lines are harder, but depending on the scale you want you might be able to do those with a displacement map instead.

The Developer Rig comes with a "Breast Valley" morph. Maybe you could copy that to an item of clothing that doesn't have it?

Dynamic cloth is definitely what you want. Tons of clothing items here at Rendo and usually cheaper than conforming cloths. Big Hair 2.jpg

The biggest problem I have with dynamic is the lack of elasticity in the algorithm.

Like chromestar said, practice :)

One way I do morphs like that is to use the "sag" morph brush. and make the "gravity" direction the direction you need.

You will also use flatten and smooth. A lot of the work will be in making up for the lack of brush shape control. It's round. That's it.

It would be nice to be able to use an ellipse for "between the breasts".

Sometimes, I use a magnet then tweak that result with the morph brush. You can also go dynamic, then morph on top of it. But the lack of elasticity in the cloth sim means you're never going to get what you want without hand morphing

This took just a couple of minutes, I started with sag, made it +x direction so I can change camera and it still pulls "front". Then I used flatten, smooth, and tighten, usually with small brushes and small values, (but cumulative). All at subd 0. Check in the subd you're going to render, though. I turned the transparency up so you can see the body. I made no effort to fit beyond the area I was morphing. Is this the effect you're looking for?

You could create a magnet set to do that. Or a donor morph. Certainly, to get you started. There's no built-in magic, though :)

Dynamics with elasticity would probably do it. I even tried to simulate it by setting up a dynamic sim, then having the breasts grow during the sim hoping it would stretch the cloth across the valley. Didn't work. Still think it should. Imma try again :D

Yeah, nah. Dynamics loses the edging fillet. That's the other issue with dynamics. You can't have edge thickness. You can add a displacement map that can do it, but not for close ups. 18 very fast cores, Xeons. 128GB RAM. And still, dynamics on that leotard, (quads only), exported at subd2 and reimported and made dynamic and it took forever just for one frame. I don't know what's being used for math, but it's slooooooooow. higher res meshes in blender and sim essentially in real time. maybe it's time to borrow the blender sim along with cycles. The current cloth sim is 20 years old, now?

For things like this edge fillet there is the 'soft decoration' group. You can assgin by material.

The Poser cloth room does a good job but yes it needs a brush-up.

If you are using Project Evolution: there is a clothing dev. kit for that figure available at CGBytes with template geometries that have exactly the kind of morphs you are after.

I do use dynamic clothes, but the lack of thickness is a drawback. Just doesn't look real, especially in close ups.

This product has a dynamic quilt that's very thick, and works really well:

I have no idea if the same technique could be used with clothing.

There are various solutions. You can:

  • make soft decoratiion hem doubler.
  • replace the midplane mesh with offset surface before render.
  • use displacement during render. (FireFly)

I have been on a quest to get that "spandex" chest look. I was inspired by an image I saw on DeviantArt. I asked the artist how he got that look. He used V3 and the cloth room on the V3 bodysuit. (I have not had the same sucess with V3 or V4). It does have to do with settings and I have yet to figure the right ones.

I wonder about the utilities for use with DazStudio. (Sickleyield's products for DS characters). It would also be a great thing if modellers took that into consideration as well.

For conforming clothing select chest make a magnet for each breast. Thinking of each breast as a sphere, put each mag base at or a little behind the center of the sphere. Position and scale the mag zone to surround the breast. Then select the mag and increase scale to PUSH the garment away from the breast. You can fine tune with x y and z scale as well as the movement dials. If you get a crease under the breast select the mag go to properties and add the abdomen actor so the magnet moves that too. And you can add a magnet positioned with its base in the center of the chest to take care of the cleavage area. Remember where you place the mag base is essential because it defines the origin of the displacement field. Make a nag for each breast and use x and y ROTATION to get very realistic breast movement!

In Dynamics - start with your figure scale at X=90% and z= 90% at the end of the simulation make sure the scales are back to normal (100%) this forces the "fabric" to stretch Never fails for me

Thanks for those two above tips. Will try.
