Major Project: Initial Silk/Fabric Tests

I began working with some shaders and textures to try and create a silk texture for the line 'When I think of hope I feel silk'. I remembered a link to a velvet shader on Heightened3D.com so I decided to have a quick look on there for any relevant shaders since there are no fabric or silk presents in Arnold. Since the majority of the presets are either metal or plastic, I wanted to see how other people created fabric in Arnold... but the majority of the tutorials I found were for Cinema 4D and not Maya. I ended up working with this shader initially, but I wasn't that happy with the results as I felt it looked more like velvet than silk. I also experimented with adding a very subtle bump map using the Cloth shader to give it some sort of texture to the surface.

Next, I used the Brushed Metal preset and adjusted some of the settings...turning Metalness off and Specular on. I worked mostly with the roughness, anisotropy, and rotation channels under Specular. I'm not sure which results I prefer more, but I don't feel like either of them achieve what I want just yet. I definitel need to create a bump/normal map so I can achieve the appearance of long silk fibers.

To create the fabric in this test (which is only temporary since I want to create some folded fabric height/normal maps to put on a sphere) I created a sphere and made set it to be a passive collider and turned up the stickiness so the polygon plane (which I turned into cloth using the nCloth silk preset) wouldn't slip off. I also am not going to label these tests just yet since the initial shader I downloaded and tried uses several ramps and mixing nodes and because I want to create other height/normal maps as well.

  1. Shop our silk fabric in an array of colors and elegant prints. Our silk material is available in various types including silk chiffon, taffeta and more, and is ideal for high-end fashion projects.
