How can I use more sprite collection in Tile Map?

[kingooo]

I need use more than one sprite collection in Tile Map, because my tile map very large.
but you tile map only have a sprite collection.
Can you give me a    suggestion to  solve this problem.

The tilemap only supports one sprite collection (intentionally, for performance). You are free to create more than one tilemap at the same location, or along a path for a second set.

But The  Multiple Materials in a Sprite Collection can?t use in Tile Map，
Can you support this ？

You can have more than1 material in a Tilemap, but it is limited to one sprite collection. Performance is a real concern when you have more than 1 material and in most cases you can Jbuild it carefully using 2 tilemap a on top of each other.
