light and shadow of the clothes simulation are unnatural

Hello.
I made clothes and applied clothes simulation in Unreal.
I liked the clothes simulation I applied in the new project for the test, so I imported it into the project I was working on and set the same simulation variable.
In the project under construction, the simulation of clothes is not smooth and the shadow and light are unnatural, unlike when tested in the new project.

Please pay attention to the skirt part of the video.

I tried to find the settings or options I thought were relevant and set them the same, but I couldn’t find out what caused them.
Can you help me?
