I have recently purchased Poser 11 and have been viewing tutorials for the clothroom specifically... I have followed the tuts to the letter and after calculating a simulation to the 30th frame the screen quickly flashes a Poser character (torso) and quickly flashes back to the beginning of the simulation as if it hadn't been calculated.... When I play the simulation that was just calculated, it clicks through frames 1-30 and nothing happens as if the simulation had not been calculated... I checked the Poser forum at Daz and it was suggested that I check the Smith Micro download manager to see if there was a specific installer for the clothroom that I had overlooked during the program installation... but of course there was no such animal in the SMDM.... I contacted support at Smith Micro and he suggested that I, in the render settings in the preview tab uncheck the OpenGl and check the SreeD... which I did and I stlll got the same non-results... His latest suggestion is for me... after the simulation is calculated I should save the project... I am not on the computer with Poser right now... I will try that later today, but does anyone here have a similar issue that you perhaps resolved? I am on Windows 10... Poser 11...AMD Radeon graphics processor ... and just learning Poser... Help please Steve
