I remember you from the original post! Glad you're still interested!
At the moment it only supports C4D naively. However you can still use it's function if your (renderer) has its own bake function, like Redshift, which has “BakeSet”.
In this image we bake our Redshift render using the Redshift bake tool first, after that we can transfer it to a new model / new uv set using R.T.T.

Hairs need to be converted to polygons first.
As for your hairs, I'm not sure: If the Redshift "BakeSet" can bake them to their individual planes, then you can use this plugin to transform them to any “low poly” mesh like in the video.
S22 might take a bit, but I do plan on it.
Best,
