Hi RayTracey,
I in the earlier post in your blog, I remember, that the Brigade showing some pretty good implementation of MLT and pathtracing, clearing caustics and tough scenarios with ease. I remember, that there was an interior, which was lit only by an opened door and the brigade implementation of MLT was been able to lit and clear the image really fast, comparing to the pathtracing. There was another scene with a ring, that showed caustics resolving pretty fast. I was wondering, is there an option to implement and add this kernel, that Brigade was using, into Octane, to speed up the rendering, as the current PMC, pathtracing or even Diffuse render in directlight mode are not efficient , slow to render. And is there a possibility to finally add a switches, so we can disable caustics for indirect or direct light sources, together with turn on/off lights sources, bumps, etc., known as diagnostic mode? This seems doing a great job in terms of speed up, in other unbiased render engines, GPU and CPU based, cutting the unpleasant fireflies, speeding the render.

PS: To add to the list with the optimizations, that can be made real time, trough all the materials, with those switches, that will give us a lot of speed up:

wow, it seem that in brigade you could have hdr environment and sun together
it would be nice to have the same thing in octane also

I agree, those optimizations would be awesome!
Complete realism is great, but not always necessary for renderings, especially for things like product renderings. you can often get a better image which renders faster but "faking" some stuff.

I still don't see what's so special about it ?
The renderings look so great because of the "dirty" texture the Scene uses.
There is Lumion3D and other Realtime Engines that do the same or even in a better quality.
So almost every photorealistic effect comes from those (photo-)textures, the rest ist some AO, reflections and directlight.

Correct me if I'm wrong.

Kind regards

That's not right, it's ray traced.

Its not baked shadows or not using shadow maps as lots of realtime rendering engines do. Its raytracing. Just google about it.
