Such as the tile , I failed to find any function in UE to change them dynamicly by C++,what i can do to implement it?
Can you explain in more detail what you’re trying to achieve? I suspect the answer, in any case, will be “you need to create a custom material.” You can start by copying
MI_CesiumThreeOverlaysAndClipping. If you need to customize any of the layers or layer blends, you’ll need to copy those as well (or you can add a new layer).
