Re: The flickerfree animation challenge

Post by lighting_freak » Thu May 28, 2020 2:42 pm

Hello all,

Almost one year ago I had almost same troubles but with BiDir and Metropolis:

viewtopic.php?f=4&t=1198&p=14635#p14635

Unfortunately it wasn't resolved during that time.
If really the metropolis sale causes this, will it appear with Sobol or Random as well?

What about pure MonteCarlo sampling if one don't care of time but of quality and correctness?

Thanks for keeping this thread alive until a real solution is found.

Hi,

another half a year is gone and with animations the "flicker" issue remains.
Some frames seem to become brighter than any others. I'm working with Metropolis and BiDir.

Thank you for your response.

The problem in this thread has nothing to do with BiDir, it was about Path+Light tracing and, as far as I know, it has been solved.

I'm not aware of any problem with BiDir, nor any has been ever reported.
