Explosive dForce

Victor_B

Hello.

I trying to create some dForce clothing. So I loaded 3d mesh (~ 16k facets), added dForce Modifier (Dinamic Surface) and ran Simulation with default settings, and BOOM!!! CRASH!!! BOOM!! Cloth exploded in 30 seconds. See picture.

Does anyone know why?

Usually it's because the mesh isn't properly stitched together. Studio can handle normal clothing where the edges and vertices are close to each other, but dForce needs to have the mesh welded or else the parts just fall everywhere.

It can also be a problem with non-manifold shapes. Look for faces of the model which intersect with other faces. Or faces which are contained within the outer shell of the object.

Thank you.

And one more question. Is it all what dForce compatible clothing requires? Just add dForce Modifier to it and that's it? Do you know a good tutorial for creating dForce clothing? Thanks.

For you own use, just applying a dForce modifier would be fine (though you'd almost certainly want to adjust some of the settings, and might want to use weight-maps to control the effects). For sale you'd probably need to rig the item so it was at least partially usable without dForce, unless the design was such that rigging made no sense.

When a dForced item intersects or is intersected by another object, even parts of itself, or if an item has drastically different dForce settings, such as material density (90 on one and 180 on the neighboring surface), it will explode. If hair passes through a dForced item during an animation (transition from standing to a pose), the dForced item will explode. If two overlapping items have dForce applied and are not on separate collision layers, and are too drastically different (i.e. heavy leather jacket over a silk shirt), they will explode. If a dForced item is clamped between two objects, such as the side of a shirt pinned between the body and the arm, the dForced item will explode if its Dynamic setting is above 0.

Clothing that is marked as dForce will already be set up for it - no need to add the modifier.

Older clothing, and newer clothing not marked as dForce, may or may not work, depending on the mesh welding. These can be compensated for with the Geometry Editor, by selecting the polygons on either side of the seams where they fall apart and creating a new surface for them, and setting their Dynamics to 0. However, these will act as anchor points, and may prevent the rest of the item from doing its dynamic thang.

You can also load the item and unparent it from the figure, position it around the body, and let dForce hang it on the figure. This doesn't negate the welding issue, but will bypass the auto-fit function, so it will hang more loosely on a figure and not conform to the shape.
