I just came across this interesting technique to help retopologise complex geometry - in this case cloth from Marvelous Designer.
Especially the step involving transferring vertex 3d position to the low poly flat retopo object via its shared UV coordinates with the hi-poly object was very cool. Using that to basically warp the flat plane to conform with the hi-res cloth.
I was just having a look to see if this would work somehow in Blender - I thought maybe the data transfer modifier might work, but no luck so far.
Has anyone ever done this in Blender? I wonder how hard this would be to create a script for…
