GridMap hide floors above current floor for editing hidden parts

[dwidge]

Hi, is there a way in the editor to hide all floors above the current floor so that we can see within a 3D building with many floors? We can clear away parts of the upper floors when we need to edit something on a lower floor, but have to rebuild the upper floors each time. We could use one GridMap object per floor but will that affect performance for tall buildings?

Using more GridMaps does not really affect performance in a worrying way.

What matters for performance is the Octant size and how many different items are placed into a single Octant.

Each Octants combines all cells with the same item into a MultiMesh, so if you have very large Octant with a single item it is peak efficient, but if you have a very small Octant with a different item placed in every single Octant cell it is peak inefficient. Also each Octant updates on changes on its own so that is also important for runtime changes.

Thank you, will try use multi GridMaps.
