Where should XPlane12-Ortho-Ireland go in scenery.ini with Map Enhancement VPro?

scenery_packs.ini order (XP12) with Map Enhancement VPro + Ortho

In X-Plane, the general rule is: airports on top, overlays next, orthos/meshes at the bottom. Anything that’s a base mesh (orthophoto tiles, UHD mesh, HD mesh, etc.) wants to live down near the end of the file so it doesn’t get “covered” by another mesh above it.

So yes—your instinct is basically right: if Map Enhancement VPro is providing the ortho/mesh layer, it should be at/near the bottom, and any other ortho mesh (like XPlane12-Ortho-Ireland) needs to be placed relative to it depending on which one you want to “win.”

Recommended layering
Use this as a template:

1. Airports (all custom airports)
2. Global Airports
3. Airport scenery add-ons that sit “on top” (libraries don’t matter, but city/landmark sceneries do)
4. Overlays (things like X-Plane roads/buildings overlays, ortho overlays, simHeaven-type overlays, etc.)
5. Orthophoto / Mesh layers (this is where Map Enhancement VPro and XPlane12-Ortho-Ireland belong)

Where to put XPlane12-Ortho-Ireland specifically
It depends on what you want:

• If you want XPlane12-Ortho-Ireland to take priority over Map Enhancement in Ireland, place XPlane12-Ortho-Ireland below Map Enhancement VPro (lower in the ini = higher priority for mesh).
• If you want Map Enhancement VPro to take priority (and only use Ireland ortho if/when Map Enhancement isn’t active), place Map Enhancement VPro below XPlane12-Ortho-Ireland.

Quick sanity check
The easiest way to confirm what it is: open the XPlane12-Ortho-Ireland folder and see what’s inside.

• If it contains Earth nav data and lots of .dsf tiles (and typically textures), it’s a mesh/ortho package → keep it near the bottom.
• If it’s an overlay-only package (sometimes named with “Overlay”), it should sit above the orthos/meshes, in the overlay section.

A couple questions so I don’t steer you wrong
1) Is “XPlane12-Ortho-Ireland” a full ortho mesh (Ortho4XP-style tiles), or is it an overlay-only package? (What folders/files do you see inside it?)
2) In your scenery_packs.ini, what is the exact name of the Map Enhancement VPro entry line (just paste the line)?
3) Are you also using any overlay packages for Ireland (anything labeled “overlay,” “simHeaven,” etc.)?
