Romanian artist Marius Silaghi has released TurboReverse, a plugin version of his Subdivision Reversion script that recreates the subdivision levels of an already subdivided mesh, maintaining existing UVs. New features include:
– 100 times faster thanks to being a native plugin
– Ability to reverse just parts of your models based on your selection
– It can reverse multiple iterations at a time
