Firstly, your help and instruction is invaluable. You have to be the most patient and kind trainer on earth. That being said, I ended up using the textures with the triplanar off and used the UV tag inside the nodes to fix my current problem, and I think it is working well. Your explanation of how points could change in the Alembic was something I was guessing at, but didn't truly understand. I plan to experiment with the triplanar, baking UV's, and your latest noise breakdancer from mixamo. All of this current problem came out of a project where one person animated a character (character object) in one project, but then we were trying to place it into tracked footage. However, we couldn't seem to move the rigged character animation to a different area of the scene. This is probably evidence of another gap in my learning. So the alembic was used to store the motion, but there was probably a better way.
Thank you again for your responses Dr. Sassi, I won't take up any more of your time this year! -Ha!

I want to thank you for this, not only the quick timing, but the quality solution. Your idea does work with the triplanar modification removed in my actual project.

If I had to use a triplanar in my material, is there a way for that to work? No need to respond immediately, and thank you Dr. Sassi!

I have a material which doesn't pin or stick under certain circumstances. I have been working on solutions for days. I have created a simple precise example scenario to show you. Unfortunately, I have to begin at this step, rather than from an earlier point in the process. It has a baked alembic animation of a human puppet walking. If I place a material with a maxon noise, it doesn't stick/pin to the alembic. Is there a way, beginning with the linked project file to attach the material and it not move/swim across the object as it moves? I have tried pin material tag, RS Object-Geometry Reference, and mesh deformers, but was unsuccessful. Can you help?

There are 2 video files inside the folder, of the current outcome, and the desired outcome. While I understand that I can make it work (evidenced by the desired outcome video), I have to learn how to work with only the baked alembic source file, rather than the entire original project.

Thank you.

I was the one who originally made this post and ticket. I was able to visit error free on AT&T and Lumos Fiber/T-Mobile fiber a couple days after the error was reported in Brazil. I am on the east Coast USA. Thank you Dr Sassi.

I just checked on my end, T-Mobile ISP. I cleared cache, Chrome new incognito, disabled cache in networking and it fails again. This time I can’t get to the main page. The cookie question pops up, but the moment it does, the white screen replaces it (with only the cookie-question icon showing). Firefox works fine.
In closer inspection, a dynamic JavaScript, “CuKSISK.js” lists a content-type: text/javascript in Firefox, but in Chrome, the same js has no listing for content-type in the response headers.
The dynamic script names change every now and then, but the same issue of not listing a content-type for one or more scripts in response headers is consistently present in Chrome. I have sent such logs/screencasts/etc. to support.

Firefox browser will work as Maxon troubleshoots.

Dr. Sassi, the biggest issue for me as I was working with Support Team was that they couldn’t see anyone else having the problem, and that they couldn’t reproduce the error. Please let them know about these other reports from the eastern USA. Perhaps they will narrow it down.

Yes, this is the exact issue I have. However, may have narrowed it down to a smaller .js file and that file not having their MIME-Type set. All of the other scripts have a proper MIME, but this one does not:
I see errors in 3 .js files:
CyjJQS-n.js
DcQYf4Dz.js (MIME TYPE is not listed under Chrome/Safari. But in Firefox it is shown as Text/javascript)
B_4WZ4t6.js

This is exactly the error I see here in SC.

One of the challenges from support was that they only had my support ticket on this subject. While I tested on countless systems/networks, they could not reproduce the problem. When I sent several videos of me asking completely random people to try on their network, I think they had a starting point. I say this so affected users will actually open a support ticket and let them know as much as possible about browser/ISP, etc. I know IT can be tough, so perhaps this will help.

Hey CSpill, I am the one who reported it. I am in the southeast USA. Please pass on as much of your situation to the support staff at Maxon. Perhaps if they discover others who have reported the issue, they can narrow it down. I have been getting help, but it still hasn’t worked completely.
I did find a work-around. If I use the Firefox web browser, the site loads fine. I have many theories, and have shared them with support, so hopefully they will be able to figure it out.
Try Firefox, it may work in the meantime.

Thanks again. I did not know about the zip file restriction. I made the .har Google Chrome archive, but I couldn't upload it to the Zendesk on the support-side ticket, so I tried zipping it. I have uploaded the original .har file to the google drive share above and the rtf file which explains what my research discovered.
