Hi dear friends,  
I had 500 buildings in a single tileset and it was working fine. But after creating 950 buildings tileset I am sometimes getting “fragment shader failed to compile error”. Please let me know the reason behind it and how can I solve it. For reference, I have attached screenshot.

Thank you.

The tileset has been created using FME not cesium ion.
