Hi

I am a newbie in model making.

I want to know what kind of model making tools can do mipmapping and texture altas. is there any tutorials?

And I wonder if Cesium can support this kind of models.

Hi Chris,

Cesium can load glTF 3D models, which can have mipmapped texture atlases. This is actually how the textures are for the default Cesium models:

Under the hood, Cesium also uses texture atlases for billboard and label rendering (see TextureAtlas.js), but these textures are not mipmapped because they generally have a one-to-one texel-to-pixel ratio.
