Does anyone use path tracing for live renderings? I think that is the question.

    Is that even released yet? Or demo-able? I thought it was just "in progress" for ages?

        Has Octane 4 really been released? I see the demo video, but going to the website, everything is talking about Octane 3, not 4. Even the purchase page says "Octane 4": https://home.otoy.com/render/octane-render/purchase/ https://home.otoy.com/render/octane-render/purchase/

        "The Future of AI and GPU Rendering" I've used Octane and I think what they are best at is hype.

        They're not even very good at that. The framerate of the VERY FIRST clip with the statue of liberty at the start of that video is horrendous.

  People are definitely working toward it, at least.

      epilepsy warning The demo is amazing on its own as a piece of art, let alone it's done programatically, let alone it's rendered in real time, let alone it's just 4k.

  There is a nice Quake 2 demo showing various settings: https://youtu.be/x19sIltR0qU https://youtu.be/x19sIltR0qU But I think we are still some time away from real time noiseless path tracing. Although more clever denoising filters for the first samples are getting much better. And ofcourse you can decide to use a very low number of bounces. This will give a darker inacurate result but still can give a feel of global illumonation.

  Blender's path tracing engine, Cycles, supports realtime use in the editing viewport. Unless your machine is quite powerful, however, it doesn't render anywhere close to 30fps. Instead, it iteratively updates the viewport. It is fast enough that this is tolerable and useful for many workload+workstation combinations.
