Occlusion texture doesn't work

Hi,

We’re using occlusion texture as a detail texture in our 3D Tiles terrain, as suggested here: How to create detail texture? - #5 by AndreasRemograph

It works well in Cesium ion and in Cesium for Unity, but not in Cesium for Unreal. Is there a known issue with the occlusion texture support in this plugin?

We’re not aware of any problem there. Can you share screenshots of what is wrong?

I know it’s kind of a workaround suggested by Sean, but it works in Cesium (first), also in Unity (second, although quite faint) but not in Unreal (last)
