I created a level using the Cesium plugin as the background and rendered 2,400 frames using Movie Render Queue. However, an unintended issue occurred in the rendered video, and I have a question regarding this.
There were errors similar to the one shown in the attached image (filename: Cesium Render Error) that appeared intermittently throughout the video. Although it only lasts for a few frames, I want to know how to fix it. I tried increasing the number of warm-up frames to solve the issue, but it didn’t help.
Also, up until recently, the rendered result didn’t have any watermark, but now there is a Cesium watermark on the bottom left corner of the video. I tried rendering 2-3 more times to check if the error appears at the exact same frames, but I couldn’t confirm that.
My questions are:
- How can I fix the rendering error like the one shown in the attached image?
- How can I remove the Cesium watermark on the bottom left corner of the rendered video?
Hi @nuriarchive, welcome to the community!
I’m not sure what you make of those artifacts. Are there any messages in the log when it happens by any chance? Can you help us to reproduce the problem ourselves so that we can investigate deeper?
As for the watermark, most data providers - including Cesium ion and Google Photorealistic 3D Tiles - have on-screen attribution requirements, so removing the credits would violate those terms. There’s no built-in way to remove the credits, other than by avoiding datasets that require attribution (which is pretty much all of them that are publicly available). If you’re sure you’re in the clear on the legal front, you can manipulate the credit display by hacking up the CesiumCreditSystemBP included in the plugin.
Thank you for your answer
1. Render Error
In the attached video (at ""25), you can see an issue where a map tile appears to be missing when rendering the video using Unreal Movie Render Queue. No separate error logs were displayed, either while moving in the viewport or after the video render was completed. The method to reproduce this issue is quite simple: place the Cesium plugin in the Level background and render a video from the Level Sequence. The camera movement only involves transitioning from a high altitude to a low altitude, which is the same as in the attached video.
2. Watermark
My original goal was to render the video without the watermark. However, if there are legal issues related to attribution, I will proceed with the current approach. That said, I searched for the CesiumCreditSystemBP you mentioned and looked through the BP Detail, but I could not find any options related to modifying the credit display. Could you provide more detailed instructions on how to change the way credits are displayed?

Can you reproduce this in the Cesium for Unreal Samples project as well? We and others frequently use the Movie Render Queue to record videos, and don’t usually see these artifacts, so it’s not obvious what might be different in your case.

Right, there are no options to control this. That’s why I described it in my last message as " hacking up the CesiumCreditSystemBP included in the plugin." This is not something we support out of the box, and not something we can provide instructions for.
