I d like know if it would be possible to edit the material shader of the google earth tiles with ultra dynamic weather , so that I could add snow or water aka rain to the scene , not just in the air but really on the ground … so far I couldn’t find the material … any ideas? or maybe its just not possible … many thanks in advance … cheers Tom.
The material that Cesium for Unreal uses to render tiles is called
MI_CesiumThreeOverlaysAndClipping and it’s found in the plugin’s
Content/Materials/Instances folder. Whether that can be modified to render rain or snow? I don’t know. It’s not obvious to me how to do it, at least.
Hey Kevin, thank you! Yes I actually found that material but I m not sure how to edit this … can I just import it into my ue seesion? Maybe the video made by the developer Everett Gunther explains it a bit better what I d like to achieve. At 00:44 you ll see the end result and at 12:00 you ll see how he implements the material function … so I wonder if this would be possible with cesium material for the tiles. … Cheers Tom.
Just copy it and paste it into your project using the Content Browser / Content Drawer in the UE Editor.
Sorry I can’t take the time to watch that video to understand whether the technique could be applied to a Cesium3DTileset. I suggest you try it and let us know how it goes.
Alright -thank you - I ll give it a try and let you know …
Hey Kevin, the first try was very successful … I have to admit that I forgot to switch on Show Developer Content that’s why I couldn’t see/find the material in the first place - now its obvious of course … I modified the gltf function by adding the UDW function for snow effects and voila; now I have a couple of sliders to control the appearance of the snow … next step is to implement the UDW function to add snow over time and to find a way to control a slope/angle value … so far so good … I ll keep you posted*
