Vray animation flicker

[Dini009]

Could you please somebody help my why is the animation flickering in the shadow?

Please take a look and if you could just help me why is this flickering? Is there a fast solution for this without increasing the render time? Thank you!

i'm miles away from a pro, but could you try putting light cache subdivs to 3000, retrace to 8.0?

Thanks Leeds

The problem is that the render time cannot really go up any more.

Thanks for your suggestions.

Perhaps you could drop the noise threshold a bit and use the few % of the denoiser in post perhaps to re-balance the render times?

I've been trying this for 10 hours straight, watched a lot of tutorials. Also saw that you have to prepass the animation and render it from files again.

I cannot really do that I dont have that much time, and I'll using a render farm it does not work there, or for double the cost.

Is there a simple solution for this? I dont know.

You can try to set GI to both brute force. Your scene might be one of those where this is faster (with 3 bounces). There is no way it can flicker.
If that is not working because it's too slow, you'll have to set the lc subdivs to 3000 and retrace to 8.

To get your old render time back you could:
-As Leeds suggested, drop the noie threshold a bit and use the denoiser to cleanup the image.
-Turn the reflective and the refractive GI caustics off.
-And you can try to clamp the secondary rays more (max ray intens. under global switches) try something below 10 or even below 5.

Post screenshots of your settings and maby the scene itself if you're allowed.

Thank you so much! I'll try that now!
