I am rendering a walkthrough with vray where the objects at the far end keeps appearing and disappearing in the render. So, in the final output it shows as flickering. Some trees also keeps doing that. i used vray proxy mesh for it. I am saving the IR map for 10th frame separately to save some time in the final render. I am not using LC for the exterior render.

Also in interior some spot lights in the ceiling does the same thing. I saved LC and IR map separately for interior.

Can anyone help me get out of this unique problem.

I have had the same problem with spot lights in an interior animation, and it seemed that I just had to crank up settings to a higher level. Not only IR map quality (used a medium or high preset), but antialiasing settings as well (adaptive subdivision min 0 and max 3). You may also have to change the QMC sampler settings. The default 0.005 (for 1.47 version) may be not enough, try 0.003 as suggested elsewhere.

Lambros, Thanks a lot. Increasing the AAA issue solved the problem. I tried also increasing the QMC but AAA done a great job by using (adaptive subdivision min 0 and max 3). But, it actually increased rendering time to almost double.
