Is Nvidia APEX Cloth still needed?

I currently have a problem with the cloth tool of the Unreal Engine. When I set up a Cloth Asset, for example a coat, with buttons hanging on it, then the buttons are calculated differently, even though they have the same painted cloth values, which leads to an offset between the coat and the buttons.

I looked at Owen in the Content Examples project, who also wears a coat with buttons. Here the simulation works perfectly. If I look at the import path of his cloth asset, then i can see that Epic imported an apex assets here, which means, that they didn’t use their in-engine tool as basis for the simulation. Does this mean that the Unreal Cloth Tool can’t handle additional geometry like buttons and i should still use Nvidia APEX Cloth?

That would be a huge problem, because there is no version of Nvidia APEX Cloth for Maya 2019!

Can somebody help or give more informations on that topic? Thanks a lot
