I think I have found out that it is caused by the number of bones influencing that part of the mesh with the cloth on it. Correct me if I’m wrong but I see this as you can not have more than 4 bones influencing any cloth simulated mesh. This is a problem for me however because I am simulating a dress on a character so it is influenced by most bones. Do I have to cut the dress into small enough pieces that only 4 bones influence each piece or is there a more elegant way to work around this. Also can I just disable this warning, because this simulated dress worked just fine before the last update.
