Google 3D Tileset lights

Hi, is there any way to build static lights with google photorealistic tiles? I’d want to have night lights, so I need a huge number of spot lights and they must be static.

Do you mean just adding lamp posts or something to the world scene? Just add them like normal objects. You probably want them to have the world anchor so they don’t follow you around when cesium resets the center.
You’ll also probably want to orient with local normal if they aren’t near the chosen ellipsoid center. Lights should work as normal.

no I mean that I need static lights, they normally are baked into the texture/lightmap of the mesh, but using cesium I don’t have a static mesh. So my question is, is there any way to bake static lights?

Doesn’t sound possible to me. One of the major features of Cesium is dynamically streaming in meshes. Baking lights statically into geometry doesn’t really fit this paradigm.

You could “clip out” parts of the terrain you want as a gltf (released recently), then do whatever processing you want on it after. But unfortunately, Google Photorealistic Tiles does not allow this workflow due to terms of use.
