How to crush a prop

mike_disc

Hi all !

I'm asking me what was the best way to crush a prop like tee shirt on the vertical axis.

I've tried to use a d former without succes, and Aldo tried to change the vertical scale also without succes.

Thanks for help

How does it fail to work with those methods?  What do you want the result to look like?

In fact i would like something like shown here https://www.daz3d.com/clothes-on-the-floor

when using deformer prop seems to be streched with not natural aspect :/

dForce simulation seems like the answer.

Agreed,

For this method:

1. Select the Item
2. Open the Simulation pane > Hamburger Menu > Add dForce Dynamic Surface
3. If you don't already have a floor, Create > New Primitive > Plane > whatever size, Y Positive (more divisions might give better results, but don't go too high - try 50 - 100)
4. Simulation Settings > Uncheck Start from Memorized and don't give it an initial value - leave everything else default
5. Press the "Simulate" button and watch it drop to the floor and flatten out

If it goes too flat, go to the surfaces tab for that item and go to the hamburger menu for that pane > dForce Surface Adjuster

Play around with those controls a bit.

 

I'm also a huge fan of Mesh Grabber, which lets us reshape anything the way you were tring to use dForm, which I've never been able to figure out either. Mesh Grabber works really well and lets us save our results as a morph - either on the actual item or just for the scene.

Agreed as well. dForce + MG should be a great combo. I posted some examples and settings in this thread for 'fall on a surface' and 'hang and fold' ,etc. - https://www.daz3d.com/forums/discussion/647736/how-to-use-dforce-to-make-clothes-fall-down-on-floor-or-on-bed-or-in-someones-hand

PS: If the garment (B) you wanna simulate has the similiar style / design as one of the items in that product (A), you may also use Transfer Utility to transfer the Morph Target(s) from A to B. If the shape is not 100% satisfying, you still can re-sim it or tweak it with MG.

Thanks a lot,
With stimulation feature, It starts fine object starts to fall during 10 seconds, then it stops and object (tee shirt) becomes completely crazy and explodes in all directions !!!
What could be wrong ?

Is the shirt made for dForce simulation?

You could try to decrease collision distance or change collision method to best, or add more subframes to let it settle in between.

Yes prop is .DUF i will try to change settings
thanks a lot

An .duf item, just means it is packed in Daz Studio format.

Are you applying the dForce modifier yourself?

If you look at an item in Wire Texture Shaded view, and there is an area with very dense mesh, the item might not work with dForce, as very dense mesh likely will cause explossions.

Dartanbeck

Try this:

Move the item fairly close to wear you want it on the floor, but make sure it isn't touching ANYTHING before the simulation starts (frame 0) It must not be touching anything.

For dropping clothing on the floor, default dForce settings should be fine without causing an explosion. However, some items that are not meant for simulation can have separate parts that are not welded, but are touching. This causes an explosion.

One thing we can do in this situation is to check the Surface pane to see what we have.

If there is a separate surface for "Trim" or something similar, try these two things (Surfaces pane) to see which works best: With the Trim (etc.,) surface selected in the Surface pane:

Visible in Simulation > Off

or

Dynamics Strength > 0.00

 

In some situations when we just want something laying on the floor, we might not need All of the surfaces. If some surfaces are blowing apart off the model, identify those surfaces and use the Geometry editor to hide them or even delete them.

Dartanbeck

You don't always need dForce-ready items to use dForce. It's just that some things just don't work well with it, without making some parts either not visible in the simulation (the rest of the item will completely ignore it, which may have horrible effects) or just lower the Dynamic Strength, where 0.00 means no dynamics at all, but it will follow the rest of the model, still attached to it.

I will often just use the Geometry Editor to select by surface, select the surfaces I don't want, then edit > delete selected. 

Other options I use most often is to try a different product altogether.

I shop the store with projects in mind in a 'thinking outside the box' mentality. I just bought a product simply because the top it includes is exactly what I've been looking for. The rest of the product is Amazing, but all I needed was the tiny tank top!

I have a bazillion tank tops because of this search for the right one. I'd morph them to try and make them like this and I got really close on two of them. This one was perfect right out of the box, and it's normally mostly hidden in the oufit it comes with.

Dartanbeck

I just feel that I should add that, for that shirt, I don't use dForce. I use Mesh Grabber for subtle dynamics

Dartanbeck

Wow. three "that"s in one sentence? How did I manage that?!!!

mike_disc

Thanks @dartanbeck for those informations, seems works fine now, perhaps issue was made by plane and shirt too far...

Dartanbeck

Awesome! How does it look?

Well finaly i've deleted the object results was not what i was needed...
