Changing models in code (3D)

For years, i thought i could change the resource of a model on a 3d object, but now that i need to do it, i cant find an action to do so. Is there really no way to change the model to another resource on the fly in events?

If it’s something simple, just use 2 models? you can just hide the old model and show the new? You can also use position to match the…position.

its… not something simple at all. and the point of it is for states/performance like an LOD

there is an LOD extension here, tho it is an community extension and not reviewed.
i also didn’t tried myself.
might also be of your interest to see how they made it.
