I was trying out cloth again in bl 2.80 and was checking some of the new option in Angular. SInce it was a while that i used it, i looked at the online manual. I noticed that under structure > bending it states the following
Wrinkle coefficient. Higher creates more large folds.
However when i test this i kind of get the opposite of what it states. When i use higher number the wrinkles seem to get smaller and more.
See below a zip containing the sequence i rendered left is using structure bend 32 and right is using bend 2.
It also contains the blend file. The setup now with bend at 2, but you can change it in the cache to the older one, just edit the input manually.
