I noticed that the images that had sil'd images on the server were blank in a recorded demo.

Is there a way to preserve the images so that a Demo would be able to view the sil'd image as painted on instead of linked to a URL?

The URL is only used once when "painting" the sign, which is then stored in Rust's image database locally. Once that is done, all the server does is tell the client which images to use and passes them to the clients. Now, if you didn't use a unique image per sign (need to be slightly modified), then the Rust server would remove the other images as it would see them as duplicates and only keep that image for one sign.

Alright, thanks for the information, Wulf! The base was a pasted base using Copy/Paste, could that have affected it too? This was on our test server and was the only build on the server at the time. Each sign was a unique image.

The base was pasted and removed multiple times before the Demo was recorded

More than likely from the image being the same, not from the Copy/Paste itself.
