Review and Fixes

Posted this image online and received some feedback on Mr Robot. Michael and Eric (my two unofficial after school mentors) gave some suggestions on his mouth to fix the stretch of UV’s.

Michael suggested that with using Substance Painter to add two more subdivisions to the model before painting, stating “It’s a pretty good way of compensating for subdivisions effecting your uvs at render time.”

Michael also explained it was an artefact known as Catmul-Clark subdivisions, created as these only preserve border UV’s. He commented that it was more than likely a stretch UV seam.

I wanted to know what Catmul-Clark subdivisions are so had a look online. Literally I already knew what it was- just not the actual name.

Catmul-Clark subdivisions- technique used in computer graphics to create smooth surfaces by subdivision surface modelling. (Wiki, 2017).

I listened the the advice, upping my subdivisions and therefore removing this artefact.
