Next question, downloaded the physics patch from the first post, copied to a new folder, started UE4.27 editor and selected the project-file and upgraded from 4.19 to 4.27, migrated the assets under /FemaleHero_ActionAdventure into my own project, overwriting existing files.
The mesh then looks broken, skeleton is also different (new one has different order of bones)…
Also, the original SK_SkinBody_A is 3.5MB, the ‘physics’ mesh only 600K.
