Experiments with SSS and Chiang albedo inversion in my path tracer. Subsurface colors are a bit off compared to Cycles and Arnold but I guess I'll give up now after spending hours tying to figure out the reason. Time for some pretty pictures:

The free web version of "Physically Based Rendering: From Theory To Practice" is now based on the 4th edition of the book. Enjoy! (Link: https://t.co/N7CroKjKLC)

@mmalex So sorry to hear that :( Pets are family and seeing them pass away is never easy, especially for young ones. Hopefully, Winters gets to chase all the mice in cat heaven :)

I recently tried coding a simple path tracer, which was a lot of fun! I made a video about the process here: https://t.co/S5YJAtFnV9

@mmalex @maxliani @Xelatihy @ejdeon @maxliani : This is the principled BSDF which uses GTR/GGX. Specular was set to 0.5 which corresponds to ior of 1.5. Roughness was 0.

@mmalex : There's a v2 of the BSDF under dev https://t.co/gFoGJ2LF8Y which uses some albedo tables for conserving energy. Perhaps this was it?

[Asif @knightcrawler25]

@Xelatihy @maxliani Out of curiosity, is there a good way to handle the energy conservation issue between the lobes/layers? Even Cycles just does diffuse + specular for the Principled BSDF and fails the furnace test:

Some juicy information about PBRT-v4 :)

@VrKomarov Looks gorgeous!

My first baby steps in denoising of animation. That's hard. At the moment I use a lot of guiding masks for spatial and temporal parts, e.g. reactive mask with movement and ao-like mask.

Well, as outed by @pixarsrenderman last week, I made a thing for the latest RenderMan Art Challenge. Here's what I made! The title of my piece is "Catch!".

I have been working on a real-time GPU path tracing renderer called "Aurora" at #Autodesk, and I am happy to share that it will be made open source soon! See the announcement here, with more details to come: https://t.co/Naxoj5M1RQ #SIGGRAPH2022
