Look carefully at the floor in the two frames from an animated sequence pictured here. Note the difference in the way the floor texture appears. I am rendering out exr still frames; the "damp concrete" material from liveDB is applied to the plane of the floor - it is fine for two or three frames then seems to 'jump' or get re-projected for the next two or three frames and so on.

It might be hard to see but check the dark splotchy area in the lower left part of the stills - when run in animation sequence it's very jittery.

HELP! Thank you -

Update - it is still happening with a stripped-down texture consisting of only a simple noise in the diffuse channel.

Have you checked the object on an empty scene?

Empty scene using only Octane texture environment for illumination - it seems to work fine. So.... my problem is maybe lights?

Hard to estimate without seeing some animation or scene. But i can't see any relationship with lights. Maybe a kernel settings issue.

The scene file is very large - I will try to figure out a way to get it to you.

I just tried upping the Diffuse and Specular Depth, no help. Trying much larger Max samples now. (This is all using pathtracing kernel).

If you have any other suggestions before you can see the scene file, I would love it.

You may take a look for texture projection type. If it's object space based and you didn't used an object tag so it can give different result in PV.

Here is a stripped-down version of the scene. Render out a few frames, you will see how the floor texture jumps around. I appreciate your help.

I think you modelled the floor in a hurry. Obviously faces are interpenetrating and it's even visible in opengl viewport. That's the reason the flickering. I hope this solves your problem.

EXACTLY right. THANK YOU.
