hello, what do you mean by that ?
Twinmotion does not need revit, but if you have it installed it might recognize it, perhaps to offer you the possibility to install the related plugin.
export plugins for different softwares can be found there : https://www.unrealengine.com/en-US/twinmotion/plugins
I don’t use the one for sketchup, I just import directly .skp inside twinmotion.
your profile says you use sketchup 2020, if it’s not up to date (and that you moved to 2021 since then), you’ll need to save your skp files as previous version, as twinmotion won’t be able to import them
