It was my first serious experiment with TouchDesigner 099 and obviously I was really interested in the PBR possibilities. It was really exiting to play with that and really motivating to get such beautifully shaded, seemingly tangible geometries so easily.
Are you trying to use high quality materials in TouchDesigner? Are you finding your TouchDesigner renders aren’t looking up to snuff? Have you tried jiggling all the cables to no avail? You’re not alone. Many folks have trouble understanding the requirements of a high quality render.
Linear PBR UPDATE: 05/28/2020: fixed very small bug in linear<->sRGB conversion functions in glsl tone mapping TOP. --- UPDATE: 05/15/2020: turned compute tangents on for shoes - tangents must always be computed if normal mapping is used.
