fabrics shading notes
Hey there,
I did some fabrics shading tests and wanted to jot down some notes before my memory starts getting fuzzy. Below are some of the approaches I have found online.
1. V-Ray cloth shader tutorial (https://vimeo.com/102632184) by Oasim Karmieh Gumroad (link).
Mostly about using the samplerInfo node to control how reflective on grazing angle. The cloth pattern mostly comes from a bump map.
2. Michael Cauchi cloth shading research
Cloth shaders for animation or VFX paper (https://www.mikecauchiart.com/single-post/2017/01/23/Research-Tillable-images-and-cloth-shading): I have collected the scene files and maps. I have also updated the demo scene in Maya 2017 with VRay 3.6. I re-created the final shader. It’s about learning how to use his cloth shader with corresponding textures he created. To learn how to use the final shader, simply watch the innovation breakdown video (https://vimeo.com/200382633 ) (about 23 mins long).

3. Using TexturingXYZ’s microfabrics map (https://texturing.xyz/pages/getting-started-with-micro-fabrics-maps):
video tutorials + one sample asset provided by texturingXYZ. I received a sample set of maps from the founder of TexturingXYZ and is the same set of textures used in the tutorial. Basically, it’s similar approach of Michael Cauchi but using texturingxyz’s textures as inputs.

4. FlippedNormals approach
Providing lots of tile-able textures to create cloth/fabric pattern as Normal maps in Mari or ZBrush.
5. Surfacemimics textures
Lots of cloth related textures available here. Haven’t tried any of them yet.
6. ThunderLoom cloth shader for V-Ray (https://github.com/vidarn/ThunderLoom)
Texture/material resources
FlippedNormals Instant Fabrics (https://flippednormals.com/tutorial/flippednormals-fabrics/): use its tileable textures to create patterns in ZBrush or Mari.
