Loading multiple KMLs

When I load multiple KMLs the browser becomes unresponsive. Probobaly because of browser memory limits. Total there are 9 kmls files ranging from size of 3-9MB and avg file size is around 5-6 MBs. According to my research 3D Tiles are an alternate but I am new to cesium and I do not understand how to go about it. If anyone can guide me.

Is there a solution to work with KMLs. If no, please guide me with an alternate.

Cesium: 1.43
Browser: Chrome 64 bit
OS: Windows 10

Hi there,

We can convert your data into 3D Tiles as a service. Reach out to Tim, contact info on that linked page for more information.
