Hi, bought this product a few days ago and have been experimenting with it. Some observations / questions, if I may:

1. When you start a simulation sometimes you see that it's not behaving as you want. For example it might be slipping off the body and you need to start over with more vertices declared for nailing. However once it's simulated poorly there seems to be no way to reset it back to the original shape and start over. All I've been able to do is stop, delete exchange info, kill VWD, go back to studio and resend the whole scene back to a new VWD. Is there a way I'm missing to reset the simulation without having to burn it down and start over?

2. Related to above, sometimes when killing VWD, Studio crashes even though I deleted the exchange files first and so in theory they are not connected to each other. Is there a way to shut it down from within Studio?

3. More of a VWD specific question, but I have a reasonably capable i7 processor yet the simulations seem to be a lot slower at default settings than I'm seeing in the various tutorials. Are there any recommendations for settings that might be slowing things down that I could experiment with?

Thanks, this bridge and the VWD are both great products and a real improvement to DAZ Studio's functionality, look forward to getting better at using them!

1. If it's static simulation, as well as using Pin, you can use Fixed Vertices under Vertex Groups; it is easy to Clear Fixed when required; clearing unPin requires a different process. The fixed wont work for dynamic simulations. Although once the dynamic simulation has run, you can use it when tweaking individual frames.

Alt Click allows a simulation to be reset; it depends if the simulation has been previously stopped and started; I've also had issues with errors afterwards.

2. Start a new version of VWD; this will disconnect it, it then rarely crashes Studio.

3. VWD likes lots of cores; reducing Spring Count can help. For example, experiment with the minimum distances when initially setting up, and when changing 'something'. If I use the Vertex Neighbourhood option when setting up hair (another example), I'll have distance to 3, and minimum to 2.7. I normally use Vertex extension for hair, and then add neighbourhood to the scalp and some head hair - that does, however, add a lot of springs; it often looks better though - as it can help keep some shape to the hair on the head and scalp. Once my system goes above 10 million springs it gets niticeably slower; I have had over 30 million, but not since the Spring Reduction check box was added.

With hair, it can be worth reducing the distance the scalp is from the head; I usually leave everything at default, but the scalp I set to 0.06 to 0.1.
