Is it possible to import a globe with imagery into online games running on Cesium?

I was wondering since that the cesium globe doesn't work and shows only blue land on GEFS-Online and any other Cesium game on chrome, is it possible to import a globe with land into it? If so, I'd like steps on how to do it, and globes I can use.

Based on your comment in the other thread that you’re a user of a Cesium-based application, and not a developer, your question seems to be kind of irrelevant. You’re not going to be able to modify the source or behavior of the applications you’re using. It sounds like your system is having issues rendering Cesium in general.
