Hey guys, how’s it going?
I’m working on a cinematic using the Path Tracer in Unreal, and we’ve been getting some strange flickering issues on certain textuPath Tracer Problemres. The bug shows up more clearly when the camera moves, and sometimes the textures pop in at low resolution or seem to “recalculate” every few frames.
It also happens when the character is behind glass: the texture looks broken or low-res, and then instantly switches back to full quality as soon as the camera crosses the glass plane.
We’ve got some experienced people on the team looking into it, and we’ve tested all the usual suspects for this kind of issue, but nothing seems to have any effect so far.
Important detail: This only happens during render.
In the viewport and sequencer preview, everything looks fine. Only when render the problem appears
It’s exclusive to Path Tracer.
Do you guys have any idea what could be causing this?
Is it related to virtual texture streaming, raytracing translucency priority, or something like that?
Any help is super appreciated. Thanks a lot!
