Development Journal

Update (W.I.P.)
  • The feedback so far has been so overwhelmingly constructive and insightful that I decided to keep working on this, in the form of an alternative Vanilla Plus Version. It will lean towards a light overhaul, providing some identity to each entrance/exit, making them more varied. Thank you all for the awesome response in such a short span of time, I'm truly humbled by it.


For this first project I took a conservative approach, trying to offer an immersive solution with minimal editing of both the exteriors and interiors of all eleven vanilla grottos. You can check all the technical details in the Docs tab if you're interested (click in View as plain text  for better formatting) or the video above for more background information on how it was developed. The custom model used for the interior is offered as a modders resource, with all vanilla texture variations.


  • Morrowind


  • Extract the file you downloaded into your Data Files folder or use your preferred mod manager tool.
  • Enable the plugin "IGE.esp".

IMPORTANT: If using Mines and Caverns, download the compatibility ESP, extract it to the Data Files folder and let it overwrite the default ESP.

Cleaned with tes3cmd.


If doing it manually, just delete the following from your Data Files folder:

  • 1 File: IGE.ESP
  • 2 Folders: meshes\HC  & Docs\HC

In the future, if I have other mods published and you also have them installed, just delete the following two folders to remove just IGE from your game: meshes\HC\IGE  & Docs\HC\IGE.

Compatibility & Load Order

Compatible with both Vanilla (MWSE) & OpenMW versions.

Compatible with Beautiful Cities of Morrowind.

Compatible with Mines and Caverns. Download the compatibility ESP and overwrite the default ESP. Load it AFTER M&C.

If you have any other mod that alters grottos in a more significant way (essentially moving and/or altering their entrances and exits), just let me know (see Contact section below). If I have the time, I'll be glad to make a compatibility patch tailored to your needs.


You can use, redistribute and modify this mod and its custom resources as you see fit, as long as you credit Hurdrax Custos, Vegetto, OAAB Team and Project Tamriel Team according to the Credits section below.
