Daremok3, thanks for verifying my reported issue. My environment is straight forward, tested systematically on simple scenes, as mentioned clearly in my issue report.

Philemot (at the Daz bridge thread) seems to have confirmed the delay-crash issue when exiting VWD and working on it so that's good...

Hair sim still doesn't work on any type of hair, custom obj or Daz classics. Frequent 'Violation error message', usually after Vertices selection stage. Quite a few similar reports about hair sim bugs too and I think VWD is close to identifying the pattern...

I'm currently using Cloth sim to animate the hair meshes which work out quite well too. VWD is usable even at this early stage. Definitely having fun with the experimenting with interesting things you can do with dynamic deformation!

There's a very energetic discussion at Daz forum about Daz users preference for conforming vs dynamic clothing and some user rendered VWD results are show cased. Lots of interest!
