The room is Dark Places by Stonemason, the dragon from the Stanford Scanning Repository and Michael 3 from Daz3D. All materials white; no light, background from the WhiteSphereB7 HDRI. The ratio object brightness to HDRI backdrop brightness controls the contrast if the HDRI does not generate light. Experiment to approximate Ambient Occlusion and Clay-Render effects with TA.
Very compelling experiment. I'd say it looks good so far. I admit to being totally confused by the description, in that there is no light from the hdri? Is there TA optimization, because in a sense the HDRI still generates light just not with points. Anyhow, I'd love to know more. How was the render time BTW?

Thank you Rashad. If HDRI Effect is 0, Intensity can be used for TA, a bit like David Brinnen's Obscure Lighting scheme. Just set HDRI Effect to 0.001 and it does not work anymore. Render time was 80 minutes in normal Priority on my old i7 using 256 rpp.
