Extending dForce Simulation?

mikethe3dguy

Am I correct that once a dForce simulation ends, if for example it hasn't "settled" adequately, there is no way to extend the simulation? In other words, begin simulating again, but from the point where the previous simulation ended.

Correct.dForce simulations start from an unsimulated state every time.

Technically you can export the simulated result as an obj file and import it as a delta morph with Morph Loader Pro, then dial it and simulate from current status. But usually we don't do that, for instance, if we find the clothing does not drape well, we may add some Initialization Time or tweak dynamic surface a bit, etc...

That isn't extending the simulation as all information about energy and momentum is discarded, it is starting from the previous final shape and will have an abrupt changes of direction compared with the previous simulation (which would be lost on running the new simulation).

Yes, that's true in most cases... the params still need to be tweaked before the 2nd simulation ~ Then the final result might be the same.

There was one outfit that the PA recommended a specific number of frames beyond the default number, say 61.

Then set your pose at 30, then again at 45 (?). Then run the timeline from memorized pose (default A pose).

The remainder of the frames would 'settle' the fabric more fully around the body of G8F.

I did it once and it worked very nicely. But I am also writing from memory from years ago, maybe a year after dForce started. But try that process for a full, fluffy dress or something that has a lot of fabric to move around. It would be a waste of time for slacks or a close-fitting garment.
