Multiple Issues when using Google tileset

When using the Google Photorealistic 3D tiles, there are very clear seams between tiles and when trying to generate physics meshes, Unity outputs an error:
“” mesh must have at least three distinct vertices to be a valid collision mesh.

If there is any fix, please notify me.

Thanks,

What version of Cesium for Unity are you using? I believe we fixed the problem with the physics meshes in v1.1.0. The latest is v1.2.0.
