LCSM, ABF and 3D-Coat’s new GU (Global Uniform unfolding) UV unwrapping algorithms in action on the same model. According to 3D-Coat insider Christoph Werner, the GU algorithm was originally only added to fix a bug.
Voxel sculpting and retopology package 3D-Coat has gained a new, improved UV unwrapping system – largely by accident, according to artist and 3D-Coat collaborator Christoph Werner.
In a post on his 3D-Coat blog, Werner notes that the new GU (Global Uniform unfolding) algorithm introduced in version 4.0.16C wasn’t originally intended to be a new feature, but was introduced to fix a crash.
However – at least on the models shown in the blog post – the new system produces significantly less UV distortion than the existing LSCM and ABF algorithms.
3D-Coat 4.0.16C is available as the current beta build of 3D-Coat for Windows. The Mac OS X and Linux versions are still on an earlier version, according to the download page.
