Curious as to bipedal proportions, especially, as there seems to be good stylized, even with larger than life heads, eyes, yet they look "good". Is there a chart like there is for proper anatomy for drawing? It'd be great to see a comparison even though I realize there are many forms of stylized. I think that'd make a great article.

The amazing Daniel Thiger shared a new Substance Designer node, which will work wonders with your materials.
Daniel Thiger shared his own custom version of a utility node for SD, inspired by the work of Even Liaw and Bradford Smith. You can download it over here.
With my new node you can directionally warp your shapes without pushing them off screen – they will still remain at origin. You have options for how many directions you want to warp in, intensity, and also set warp direction unlike the original.
If you’re at GDC 2018 and you want to hear Daniel talk, don’t forget to visit Substance Day. His talk is at 5:30 on Tuesday, March 20th! He’s going to talk about natural materials.
