Eris is a character from our short film "Paper Lotus", designed and textured by me, while the sculpting, modelling and rigging was done by my team mate, Fu Meijo.

This character was also textured in Substance Painter, and like Amero, the paint strokes on the normal map are a little heavy handed as it is needed to break apart the smooth gradients so that the composite filter in Blender can work well (example of final look in the last pic). In contrast to Amero who looks very smooth, Eris looks a lot more organic and kinda wrinkly, to push his lotus plant motif.
