Hi all,

Been reading the docs, trying to find a way to make the tilemaps load more aggressively, from further away. I'm using Cesium to display a heatmap from a custom tile server and I want to see it with a finer resolution.

Thanks!

Hi,

This was previously discussed on the forum [in this thread](https://groups.google.com/forum/#!searchin/cesium-dev/imagery%2420level%7Csort:relevance/cesium-dev/eBgIKjw6HCE/Zw4puJ53vCQJ).

You’ll want to adjust [Globe.maximumSceneSpaceError](https://cesiumjs.org/Cesium/Build/Documentation/Globe.html#maximumScreenSpaceError) to 1, which will load more detailed imagery at the cost of performance.

Thanks,

Gabby

That thread is a little outdated and 1 is probably not the best value to use because it would be too aggressive. I think 4/3 is what we officially recommend these days.

Great, thank you!
