How to show car movement marks/footprints on Cesium 3D Tileset in Unreal?

Hi everyone. I’m using Cesium for Unreal and I want to create a visual effect where a moving car leaves behind marks or footprints on the terrain, similar to tire tracks or dust trails. The goal is for the ground to retain those marks along the car’s path on the Cesium 3D Tileset. What would be the best approach to achieve this in Unreal with Cesium terrain?

Regards.

@Unreal_dev I’m not familiar with how to pull off this exact effect, but it shouldn’t make much difference whether it’s happening on Cesium terrain or on any other surface in Unreal, so any available tutorial online should work. This one seems like it covers what you’re looking for: https://dev.epicgames.com/community/learning/tutorials/lMxR/unreal-engine-car-skid-marks-tutorial

This is for the skid marks. I am not sure will it work on cesium tileset or not. I want permanent marks on the cesium tileset. Is there another work around for this?

@Unreal_dev Perhaps something is possible using Runtime Virtual Texturing: https://dev.epicgames.com/documentation/en-us/unreal-engine/runtime-virtual-texturing-in-unreal-engine. I’m not sure, it’s not something I’ve tried.

@Kevin_Ring @janine

Hi. Do you know any workaround for this usecase?

No, sorry @Unreal_dev, it’s not something I know how to do offhand. A more general Unreal forum may be helpful if you need more specific information, as this really isn’t related to Cesium. I think @azrogers’s suggestion is a very good one, though. Have you tried it?

Just a drive by comment… this sounds like something that could be enabled using Unreal decals. We currently don’t support decals on Cesium3DTileset, but I opened a GitHub issue for this below so we can track interest for this:

We’d welcome a community contribution for this if anyone’s interested!

I don’t know how to proceed with @azrogers suggestions. I didn’t try that.

Sure. Will it be possible through decals if you add it in the next cesium version?
