"When I first tried VWD with the loincloth, I got a result back in Poser " I don't know how you have done it! If it was not the same result in VWD and Poser it's may be something else.

In demo mode you have the complete access to clothe simulation parameter and see the results in VWD but no result return in Poser.

From the manual ("demo version" chapter) "The demo version allows to run the same simulations as the normal version. The only difference is the inability to save animations in Poser®.....To give the user a real view of the simulation, the demo program, as normal program also, allows you to record images of the interface during the calculation. These images are stored in a video format and saved in a file named « Simulation.avi » in the program directory.."
