Been keeping an eye on Brigade for a while now. Its cool, but that PT noise is pretty distracting. I guess as hardware improves, it might go away.
That said, even if it was only used for things like reflections and refractions, the reduced overhead might mean they render without significant noise. And having PT refl/refractions would be pretty **** awesome.
As you can see it looks awesome when the camera is not moving but when it’s moving or when there are moving objects around… there is just way too much noise to make it usable with current hardware IMO (at least not in games).
I’ve been waiting for the render pipeline to add simple raycasting. I don’t think we’ll ever bother with a purely raytraced realtime engine because a hybrid model works so much better, but I think the idea’s time has come. Bundle that with voxels and you’ve got a nice physical simulator.
