The picture is nonsense, I know. It is only the first test of clothes that didn’t crash DAZ-Studio 4.24 on my „new“ iMac (actually it is a late 2013 iMac I bought on Ebay because of the inbuilt Nvidia graphics card). Every other attempt to simulate a figure with dforce clothing shut down the application immediately. I have looked in the forums if someone else has the same problem. But it doesn’t seem to be a known problem. I have deleted Vers. 4.24 and changed to the old version 4.20. At least there is the Save Menu accessible during the simulation (which was sometimes very helpful). But a new simulation shut down another simulation with the old version of the program. So I can’t find out what the incompatible components are; the system (Sonoma 14.7), the application or the graphic-processor (Nvidia GeForce GTX750)? As far as the picture is concerned: P3D Ursula G9, Fair Maiden Dress, Elysianna Hair BM-6 Bird Props, Some parts of the Hobbit home by Roguey and some other props Just to see if she model could be rendered. At least that worked well. After 4 or five attempts to make a simulation with the dress, I used a somehow strange and seemingly un-technical solution: I let it „sink in“ (in the brain of a computer?) I didn’t start the simulation right after opening the file, instead I waited for some minutes before I hit the simulation button - and it worked! 1 time! Every other attempts with different models caused a crash of the application. Now my question is: has anybody had the same problems or maybe someone has found a way to get around it? Thanks for reading! tl;dr: why can't I make simulations anymore?
