This mod is great, it would be really great if compatible with rso..

There is a currently a way to do that within RSO but it might be suboptimal.
You need to detect presence of remote interface of RSO and do two things:
1. Call disableChunkHandler in your mods oninit (this might require making an optional dependencey on RSO but not 100% sure).
2. Call generateChunk and pass to it original event from on_chunk_generated.

Drawback of this method is that currently RSO can spawn ore outside of chunk given in the event and there is no simple way to change this. So ideally RSO would need to have new event added that it would call after spawning resource patch and pass it's bounding box to it.

This mod is a resource spawning mod. It would take a bit too much effort to make it work with RSO for what this mod does.

Actually, I just changed this mod to be optional on rso. There are no errors in loading or generating. It does appear to operate as expected. Ores do not replace exactly (infinites will replace non-infinite), but it does a good job of providing variety.
Also, to note, it does seem to skip random chunks. But, it does work

Then can you just remove negative dependencies? Actually the mod works 'quite' well with rso, but I have to modify file to make it compatible, so hard to use in multiplayer.
