Can you do the simulations using the GPU with your Titan RTX graphic card? Yes I can. Did you use the assistants to create your simulations. Can you tell the character and the cloth/hair you are working on? I am not too familiar with the software as yet so I do not understand this question. Sorry. I did check the 'new animation' box and that worked. Thank you. I attached some pictures showing the steps in order before the simulation. However, this time, I did not get to simulate because of 'insufficient memory'. Please let me know what I am doing wrong.
