If only there is Retopology tool in SU...then we'll have use for millions of 3d warehouse models.
I was watching the plugin Wrapit for 3ds Max which was around probably the last 8 years.. It looks really easy to rebuild models to quads for easy editing or subdividing.https://www.youtube.com/watch?v=05-HMox2Df8
Many SU warehouse models can be of good use really if only something like this could be available to SU.
Just wishing here....hope some developers would ponder considering.
