When I create a dynamic clothes simulation in Poser 6, the simulation aborts after making a few steps. Could it be a memory problem?

Many things can cause this, the mesh might not be suitable for the simulation. There might be intersections with the model etc...Have you tried it with the dynamic items provided with P6 does that work. We would need a little more info to help you.

IT can also happen if your clothing item is touching the target mesh before you start the simulation.

I'm running Poser 5 with what may be low memory for doing dynamic clothes simulations (512 MB). I don't think memory kills the simulation, it just makes it take forever. More likely, your simulation settings are asking Poser to do something it can't do. If you post more about what you're doing, I might be able to help pinpoint your problem. I'm only a beginner user of Poser 5, but I have wasted lots of hours making dynamic clothing simulations work, and I think I've become fairly good at figuring out how to change the settings to make it work. Even if you have read some of the dynamic clothing tutorials, you can't begin to have a clue of all the different things that can make your simulation go wrong. But if you haven't read the tutorials, read several. They all seem to have slightly different information, and between them you can put together a bit of how the cloth simulations work. The tutorial by Jusletgo here on Renderosity is the easiest to use, in my opinion, but I've also read tutorials from PhilC and hmann which had useful tips too.

With my clothing packs, if you exceed the elasticity settings of the cloth it'll abort the render. I don't remember seeing an abort for another reason, just up the stretchiness a bit and try again.

I've had this more than a few times and deleting the simulation and creating a new one fixed all but one.....the one it wouldn't fix was a top for kate that i had simulated from the zero position to the default position then exported, i reckonthe problem was all the polygons bunched up under her armpits was confusing poser, to fix that i ran a simulation from the default pose back to the zero pose and used the resulting obj......Steve

If you can show us a screen grab of the garment.
