Hello,  
How bigger the size of .gltf model can handle cesium?

If a file over 300mb, would it not effect the processing time? If so, what are good spec for a system to handle such files.

Thanks

Hi Umar,

We are working on 3D Tiles, a spatial data structure that contains glTF tiles, to stream massive models like this, see [https://github.com/AnalyticalGraphicsInc/3d-tiles](https://github.com/AnalyticalGraphicsInc/3d-tiles)

You could also try to run a decimation algorithm on the geometry and/or use lower resolution textures to load this as a single glTF model.
