Maxon Noise Displacement Skipping Frames
-
I am working with an animated displacement, powered by maxon noise, that washes across my model via a vertex map field. The noise is animated. But for some reason, certain frames simply show no displacement, as if it was turned off for a frame, and then is back the next frame. I have placed a project file, a screenshot which listed the 10 or so frames I had to re-render individually (which worked fine btw). I also have a series of 3 frames which show what happens. Rendering on Apple M1 Max 64gb Sequoia 15.7.3. C4D 2026.1.2 and RS 2026.2.1.
I am trying to figure out if I am doing something I shouldn't be.Cineversity - Maxon Noise Error Google Drive

Hi appointment-insect,
Here is a file with the images 3, 5, 17, 27, 28, 45, 47, 58, 66, 74.

Please let me know when you get them, so I can take them off the server.Rendered on an M1 64GB, Sequioa
Here as texture

https://www.maxon.net/en/support-centerI have reduced the scene and rendered it again. I'll let you know how it goes
All the best

P.S.: As promised, the smaller setup, meaning, just one material for the displacement to smooth animation.
I rendered your scene a few times through, and the problem shows up here and there, randomly.
Since I believe that getting the simplest setup is typically beneficial, I reduced the materials needed to one, as mentioned above. I could not find a problem. I am also in the Vertex tag that updates automatically, just in case. (Nope, I did not find it to have a problem, just to be safe…)

https://projectfiles.maxon.net/Cineversity_Forum_Support/2026_Clips_DRS/20260127_Football_0002_preview.mp4Please render it and share your results if all frames are rendering now fine. It works fine here.
I have not included textures, so please add the file to your project folder.
Enjoy.

As always, I thank you for your prompt response. I have downloaded each of the zips to look at, so you may remove from the server. I rendered your updated single-material version. I understand what you mean about using a single material. But my goal is to make a material that is a simple material swapper (with displacement). Is there something wrong with doing it the way I was that makes it randomly miss the noise on frames? Like when I have a priority problem with rigged parts and the rigged parts don't reset. If I return to frame 0 a couple of times, it fixes. The football project will act similarly. Is there some type of priority problem that affects materials? And again, Thank you!

Hi appointment-insect,
You're very welcome.
Please try this RS-Mix material if that works for your workflow. This is a setup for you.
CV4_2026_drs_26_RSmm_01.c4d
In the Attribute Manager, you can add Mat.A, and Mat.B into it, as well a Vertex Tag. The names are not required, I used A and B for clarity.
Priority problems need to be explored separately.
I'm not aware of what you have explored to solve it. It can be in XPresso, in the sorting of the Object manager, or somewhere else. There are limitations.If you want to look at it, please share a file that shows that problem, open a new thread for that, please.
Given that the file is below 1MB, please upload the C4D file here. (Sorry about the long text…) If larger, for security reasons, please upload uncompressed to either WeTransfer, Google, Dropbox, Apple, or Adobe cloud services. The URL is fully pasted here, no HTML wrapper.
All the best

P.S.: Please try this if there is any problem showing up with the previous file.
CV4_2026_drs_26_RSmm_02.c4dIf I set the System in RS to a lower Bucket Size and move the timelsider randomly and fast, I can recreate the Drop out of one material.
A few years ago, we had a refresh problem with Fields, and Lionel suggested to animate one field just a tiny bit, forcing a refresh.
I hope we can pinpoint your problem.
Cheers

Thank you again. I have taken your RS Mix material, and added it to my project. Using the RS Mix, I am getting the same drop-out of the displacement in random frames. I have only one field driving the vertex map for the swapping materials. Both of the noise patterns in the galvanized gold are animating.
I uploaded the complete project to the folder I shared before. Here is a direct link to the subfolder which has the RS Mix swapper in use.

I wondered if there was such a thing with establishing displacement in RS.
Should I try Saul Espinosa over at the Redshift render forums on FB? He may know if it was a quirk in RS rather than C4D.

Hi appointment-insect,
While Saul surely has an encyclopedia knowledge about many things, including a vast background of RS, I noticed today some dropouts even with the Color Vertex map.
Which means, if you have a minute, please send your file to Tech Support. Thanks for considering!
https://www.maxon.net/en/support-centerI have not found a trigger to produce this deliberately. If you notice a pattern, please share with tech support.
Cheers
