Yes, I also changed the settings and could not understand why the clothes are so badly stretched. In the settings of cloth-properties something has changed dramatically with the change of the engine version. I made a simple project with a curtain. APEX and fabric properties were configured in MAX.
Here is the curtain in 4.14
and the same curtain in 4.16 (just opened the project as a copy in 4.16)
in 4.14 the curtain is stretched and deforms much less than a curtain with the same properties in 4.16.
Settings of cloth-properties UE4.16-version has a lot more. But I couldn’t find detailed documentation about what each of them means.
