Any way to fix this? I feel like I have tried everything at this point to no avail :frowning: . Any help appreciated! edit: It seems that it is being caused by material’s roughness. At 0 no noise occurs, increasing it introduces quite a bit of noise, and at 1 it turns into big splotches.

That makes it like x10 worse when moving. Temporal aliasing has huge ghosting effect in reflections, and completely butchers it.

sure. i got a testbed for all of this. clean chrome. clean carpaint. rough glass (this is lil bit of a cheat, rn). it does not appear as glass in the reflection in 5.3 (work in progress in 5.4, afaik), but the reflection works. and everything is pretty much stable.

But so, if you have a material at 0.5 roughness, does it create noise?

Ok, let me do an example, and you replicate the material.

Ok, I can see some noise popping in, but not nearly as much as I seem to have. What if you try moving sideways a bit? Could you perhaps apply some material to the floor, like an asphalt? No aa:

doesn’t matter if i apply asphalt. i wrote that down in my first reply. aliasing in motion is normal. this is normal temporal instabilty. just deal with it. you have to design your graphics around the limitations of realtime raytracing. it’s good but it’s not realtime pathtracing, yet. the am…

Hmm, I’m trying to design a vr driving game, and mirrors naturally are of utmost importance in a car. With ground not being so flat in color as yours, for example asphalt leaves huge streaks is using taa/tsr. Completely unusable for this. Is there a better approach to creating a mirror?
