[Max] I need help! / Re: Animation - Displacement Flickering

Ya it is hard to tell from that video because your render looks very low res and aliased.
But my first guess would be that the pixel size is not small enough for the displacement. With that small camera move Corona is having a hard time knowing how to displace
each pixel per frame. I can see you have changed it from screen to world size for displacement. Have you tried lowering the size more? It would also be helpful to show the map you are using for this. But I have had the same problem when the camera moves slow like this, and Corona can't figure out where to displace per frame based on the pixel size settings.

I hope you can figure out what is up and let us know.


Please push up the tone mapping (ACES) please. I want Corona to stay ahead of the competition.

Step in the right direction, but man Cryptomattes with this working would be the best. I am so sick of setting up RGB mattes and ID Mattes for so many objects.

I have some new idea for Corona, i think. Some fake option for sun, that help us to make situation, when sun light will go through the clouds
OR New sky model - with clouds. I never saw render engine with this option.

how about something like this? I always thought Corona had an opportunity to do something better with the standard Sun and Sky systems in renders that are pretty limited and boring to use.

I really want this in Corona, it is going to be the future of lighting workflow. Let's not wait till everyone else is using it before Corona does something about it.

I think you should try the animation preset of the UHD and see if that works for you before going to Vray for that. But let us know your results.
For us Render time is not as important as quality, so take what I say with a grain of salt.



Not that this matters, but when we switched to Corona we basically said at the studio we will only treat Corona using Path Tracing + Path Tracing and just pretend that Cache options just don't exists. I find that Corona is just fast enough that we dont look back. I hated dealing with animations and Cache in Vray, so when we came to Corona we just pretended like it was not there haha :)

Good luck on your project.


I must be weird or something but I hate the fact the materials are in real world units hahah

I would love for this to be fixed too.

Yes, the motion not working with changing topology is a big problem for us. We have had to bail on using Corona for certain projects which makes me sad :)

I have not tried that yet, as I am in a production. I will try the de-noise change on my next render.

Thank you. I appreciate you taking the time to point me in the right direction.

It is using the Intel AI denoiser, and is using Corona 4 Hotfix 1. I will see if it happens without it. Is there something somewhere that says there is a problem with this.

I have noticed some strange behavior with render elements and corona in Max. I have renders that contain no refraction, yet I am getting things showing up in the refraction pass that should just be black.

Not sure when I started noticing this. But I have been getting things showing up in Render Elements that should not be there.

- No refraction in any materials.
- Refraction pass has strange things in the pass. Like blurry splotches, and other things that show up.
- It does not always show the same strange things in the render.
