How to do LOD with multiple cameras?

Question

I have projects in mind involving heavy reliance on Level of Detail, however something confuses me with Godot:

Usually, the idea is to render a different mesh depending on the distance you are from it. So it looks easy to script that on a Spatial having several MeshInstances as child, each of them being a different LOD.
But...
This will not work if there are multiple cameras in the world, because only one LOD can be active at a time with this method :/

So I'm wondering... how is this possible to do with Godot, assuming that the project could be an open-world with a huge streamed map?

Comments

You could measure the distance to the nearest camera and determine the LoD from that distance.
One thing to think about is:
When you have one camera near at your object and one far away, the object will be rendered in high LoD. I don't know if it's better to render the same high-LoD mesh twice or two different meshes with one high and one low LoD...

This is exactly what I'm concerned about. The only way I know would be to determine the LOD at the render stage, not the process stage. But I have no idea how Godot handles it, or if it handles LOD at all.

Answer 1

You should be able to use different mesh instances, and set their "Range Begin" and "Range End" parameters, you shouldn't have to worry about cameras then.
