When exporting movies from large scenes, I'm getting severe atmospheric flickering in the distance. It appears to be a fluctuation in the "Clear/ Hazy" setting, but even appears if I turn Hazy right down to Clear and Aerial down to 0%.
I've checked on the usual suspects;
Please let me know what else I should try to fix this.
I'll upload the DGN and LRT now.

Max,
Am I correct in assuming that you are using LumenRT Update 15?
I noticed a similar flickering issue when I installed the latest version of LumenRT (Update 15). It didn't occur until after the update.
I asked Jerry about the issue. He thought it could be related to the denoiser of the new RTX features in LumenRT. I don't think that was causing my issue because didn't launch LumenRT with the .bat file, so I wasn't using the RTX features.
Since the issue only started after installing Update 15, my only solution was to uninstall Update 15 and reinstall Update 14. The problem with downgrading is that if you made changes to the scene with the Update 15 you can no longer open it with Update 14. Luckily I had only added some trees, so after a new export to Update 14 I only had to repaint those trees into the scene.
I plan don't plan on updating LumenRT until this issue is resolved.
Your question reminded me about this issue, so I just submitted a service request {SrvReqNo:[7001262142]} in regards to this issue.
Regards,Ron
Yesterday I got this response from Bentley Support:
Hello Ron,I would like to inform you that this issue resulted is Defect Report: Defect number 584381, and will be evaluated by the product management team for our regular SELECT updates.Thanks.Regards,Ankur Ashesh
Hopefully the fix is in next release.
Interesting - the response to mine went a little further;
"The issue has been fixed in upcoming released of LumenRT update 16. It will be out in next few weeks from now. Regards, Ankur Ashesh."
Let's hope those will be a short few weeks...
Hello Max,
your issue is bit different to Ron project file.
We have tried your file and it works fine, but in case of Ron we need some time to fix the issue.
Although for Ron also I am trying to fix as soon as possible.
Sorry for the trouble you both have to face regarding this.
Thanks.
Regards,
Ankur Ashesh
Thanks Ankur - do you have any advice on how to avoid this in Update 15? I don't want to revert to 14 because I have other projects also on 15 that don't have this problem. Is the problem related to camera angles/ materials/ time of day/ render quality settings/ speed? If we know what the culprit is, then we could avoid aspects of our workflow to make 15 work until 16 is available.
... have to say, the situation is such that LumenRT (update 15) is unusable for me at the moment. With Microstation CE Update 16 just released, when can we expect LumenRT Update 16?
At the risk of sounding persistent ... please could I have an answer to my first question;
Max Voigt said:Is the problem related to camera angles/ materials/ time of day/ render quality settings/ speed?
...or is there absolutely no work-around?
There is no workaround to the following concern,
If we have so, I could have share with you previously.
Very sorry for the trouble you are facing now,
We are going to release the LumenRT update 16 very soon.
one thing I can help you with from my end is, if you have the video to render only
you can share the file with me along with the amination sequences and I will try to render the video at my end.
Thanks Ankur - I appreciate your offer to render the video.My concern is for a new project that I'm starting now, so I haven't got to the point where I need to render videos yet. I'll do the work on Update 15 for now and may well come back to you for rendering if Update 16 has not been released by that time.
Hello Ankur.
I am quite new to using LumenRT but have had similar "flickering" happening in an annimation that I created recently. I am using LumentRT Designer that comes with Microstation which is Update 14. Is the Update 16 available for LumenRT Designer. If so, how and where can I get the upgrade.
Thanks in advance.
