How to dynamic change color and transparency in material layer blend?

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).

Hi Kevin, Are there any ways to add a new layer runtime(by blueprint).I haven’t found any relevant blueprint nodes.

@WuduHenry I suggest you start a new thread and describe in more detail what you’re trying to do. For example, what kind of “layer” are you trying to create at runtime?
