Solved** Applying Occlusion to Cesium Building OSM Data for AR

Cesium for Unity
1

Hi,

has anyone figured out how to apply occlusion material to Cesium OSM building and terrain data for AR applications?

2

I’m not sure what you mean by “occlusion material”. Occlusion culling? Ambient occlusion? Something else?

3

We want use the Cesium data as a masking layer for use in AR outdoors.

Sorry, I still don’t understand. What does it mean to use Cesium data as a “masking layer”?

Ill capture a video this week!

We plugged cesium into the Magic Leap 2 and are using it in AR - we want the Cesium models to overlay ontop of the real world to use as a “mask” for AR content to hide and cut into the real world buildings and terrain.

We got it! check this out!

That video looks really cool, @Geopogo. But I can’t quite tell if you’re saying everything is working perfectly (in which case we’d love if you could share what you did), or if you still have a problem that needs solving.

hey !
sorry but I didn’t find a solution to get this to work in AR/unity/urp…no occlusion…
is there somewhere an exemple in shadergraph I could follow to get it work ?
thx

I have the same problem. Assets placed below the terrain are not occluded in AR. How do you do it?

Hi, I am facing the same problem. Could explain your workflow? Were you also able to apply this to the terrain? That would be great. Thanks!

Hi @Geopogo, do you mind sharing how you get the 3D Tiles to overlay on to real world buildings?
