Stacking dforce simulation results

linoge8888

Is it possible to simulate a first "movement" with a piece of cloth (30 frames) then edit the geometry of the current pose and start another simulation over it, without having the garment reset ?

For example : 

- From frame 1 to 30, the right sleeve is torn apart 

- Then I delete some polygons on the left sleeve

- From 31 to 60, the left sleeve is torn apart too. 

as a result : the shirt looks now like a tank top.

Not really - if you edit it in an application that can preserve morphs (DS with the Geometry Editor, soem 3D Modelling applications - modo for example) then you could turn the state at frame 30 into a morph, edit the geometry, then simulate the results. However, the starting morph would be static so any movement that was going on in frame 30 after the simulation would abruptly stop in frame 31 with the new simulation.

Ok, I hoped for another way, because I failed miserably at turning a pose into a morph : saving the garment as an .obj, but the obj can't be worn when imported back ; there is no "fit to" option... I'll read the steps more carefully.

If you are using dForce you don't really need to be able to fit it.

My suggestion was a bit elliptical, let me try again:

1. simulate the one-sleeve version and export as OBJ
2. modify the base geometry (in DS or by exporting it zeroed to OBJ and opening in a modeller
3. if using a modeller turn the frame-30 shape into a morph before geometry editing
4. if using a modeller, export the zeroed and morphed shapes as OBJ
5. import the modified, zeroed version into DS and rig it from the original using the Transfer Utility
6. apply the pose as it was at frame 30
7. imported the simulated shape as a morph, using the  Reverse Deformations option
8. simulate the remaining sequence with both sleeves ripped
