Experimenting with V4 clothing in dForce... question on collision

RenderPretender

Hello -

I was experimenting with a V4 dress and pants in which the dress is supposed to be worn atop the pants. I added a dForce modifier to both, and the shorts drape quite well. But when I try to drape the overdress, it - maybe the shorts too - explode all over. Is there a feature to prevent the two garments from interacting badly?

Also, if a character is wearing more than one garment, and you simulate, are both garments affected, or only the one you have selected in the scene?

Thank you!

Make sure that they don't intersect, and adjust the collision layer value (in the Surfaces pane) for the outer item so it's higher than the inner.

I'll give that a try. Thank you.

The collision layer adjustment seems to have helped with the exploding, but I still can't understand why both clothing items are moving during simulation, and not just the one that's selected in the scene pane.

The dForce simulation will apply to any item visible in the scene with the dForce modifier applied. To drape the dress over the pants, with the pants already simulated:

1. Select the pants in the Scene.
2. Open the Parameters tab.
3. In the left column, find Simulation and select.
4. In the right column, enable Freeze Simulation.

Now the pants will stay simulated and you can drape the dress without the pants changing.

Do be aware: If you need to restart the simulation on the dress, Do Not use the Clear button in Simulation Settings. That will clear the drape from both the dress and pants. Instead,

1. Select the dress in the Scene.
2. In the main menu, find Edit->Object->Geometry->Clear dForce Simulation from Selected Item(s) and select

Also be aware: If you do hit the Clear button in Simulation Settings, your pants will have the drape cleared, but Freeze Simulation will still be enabled, preventing you from redraping the pants. You'll need to disable that to simulate the pants again.

Hope this helps.

That's very helpful! Thank you. Would you happen to know, by the way, if it's possible to pause and restart a single-frame sim? Something tells me no, but I thought I'd ask.

I'm afraid not, when you stop a sim it loses the data about how things were moving and how much enrgy was accumulated. That said, you can export as OBJ/load as a morph and start a new simulation from there but the result won't be the same, for good or ill, as resuming the original sim.
