Corona Renderer 5 for 3ds Max - Daily Builds Discussion

[VASLAVO]

hi, i hava a question / report, after the latest 3dsmax 2020 update some features of 4.1 hotfix arent working as it suppose to, for example, you can see the hdri sky on viewport but when corona map select is applied the hdri seems to be flipped on the viewport but it renders ok, the seccond thing ive notie is that i cant seem to be able to see the map from a back plane with corona light material applied, have tried all combinations with no luck, it looks black, havent tested with daily build.

Hi,

Was this working before the last Max 2020 update?

Thanks,

I have just installed the latest build, and the viewport render selection is not working as it should. Randomly chooses to render or not while no indication of the render time or noise levels is provided. It literally showing blank space.

Hi,

This seems to be working as it should for me, do you have a specific scene where this issue is occuring? If not, can you provide me with some more specific reproduction steps?

Thanks,

Rowan

well no, actually no, the new update sets the map used on the environment slot as background automatically, it never happened before, its one of those things that you notice when it happens but for sure, the background as corona select textmap appears to be flipped on viewport

Hi,

Okay, so the first issue we are aware of, it seems that HDRI's are rotated 90 degrees in the viewport when used with certain maps as reported here: https://forum.corona-renderer.com/index.php?topic=24948.0

The second issue, can you provide some more details?

cant seem to be able to see the map from a back plane with corona light material applied,

Can you not see the map in the render or the viewport or both?

Thanks,

Rowan.

(Just a reminder, this thread is mainly for discussing the v5 daily builds. For issues with other versions of Corona please use the Bug Reporting board and remember, one issue per report :-) )

Hi!

I have the same exact problem! My colleague who has the same HW configuration hasn't any till now.

It's almost 3 months I occasionally have this strange issue but is very curious you're not having it with Corona but with another rendering engine!!!
Do you use the plugin Forest from iToo Software? I've noticed that I get thoses flashes and flickerings specially by using Forest.

Thanks,

Dionysios -

PS. Probably is the wrong forum to post your problem here but on the other side I finally found somebody having it as well....

I used to have this issue all of the time (along with the CPU downclocking randomly after a while - not related to thermal throttling, and FTH was disabled). The only fix was to disable any Intel Speedstep/C-state power saving options in the bios.

Thanks for the info! I'll try to check my settings in the BIOS then.

I am having it with CORONA not VRAY
I am havign it at home with Threadripper
At work I have intel it is fine I never have it
Corona has been doign this for almost a year on two different threadrippers 1950X and now 2990WX
If it was Vray I would go to Vray support
I am having it right now
basically every night I have to go through and waste half an hour to an hour on this
been patient for a year now
excuse the anger

I think more and more people have this and would be very useful to understand why is happening! It slows down my workflow as well... :(

Hi ihabkal,

I can understand the frustration but it is very difficult for us to investigate and fix something if we are unable to reproduce it.

Secondly, please can you create a topic on Bug Reporting for this, rather than flood the daily builds thread? As this is not specifically related to the daily builds.

Thanks,

Rowan

I've encountered the flickering windows issue a long time ago (max 2017) and it appears randomly since then,only with corona, no matter the version. Never figured out what was causing the issue.
