Thank you Moonglow,
You are welcome RorrKonn,
OK three more tutorials to have a go at - an hours worth of viewing “pleasure”...?
Intermediate: Bryce 10 minute material project - rainbow texture - a tutorial by David Brinnen
Intermediate: Bryce 10 minute material project - using the rainbow texture and scene converter - by David Brinnen
Advanced: Bryce “Nuts and Bolts” - TA optimised radial lights - a 40 minute tutorial by David Brinnen
The first image, the lighting was made using the spherically mapped rainbow as a gel for TA optimised radial lights. More specifically, the render took 5 minutes to complete and it lit by two TA optimised light source with TA scattering correction and boost light used. OK it may not look like much, but as a proof of concept this shows that it should be possible to create an effect somewhere between that of HDRI’s coloured light component and TA’s indirectness that renders very efficiently.
The second image, a Stanford dragon render… TA scattering correction and boost light. I converted Horo’s angular mapped Treppenhalle2.hdr with the Spherical Mapper and spherically mapped that into a light gel that is applied to two TA optimised cubic light sources that also exclude the Stanford dragon and overlap. This projects gel light in which adding rather than multiplying, retains the colour. The same HDRI is used as a backdrop to drive reflection. Standard Bryce sun is also employed as a key light, and drives a bit of diffuse and also specular. The material was made by me from a photograph taken by Horo.
Render time 20 minutes at 256 RPP with Max Ray Depth set to 4.
Third image, lit with a single TA optimised radial light source. As shown in the third video, R = 255, G = 60, B = 25. Material made by me from photographs supplied by Horo - the model a little Wings3D project. Render time about five minutes.
