I'm building a Modular Terrain set and recently posted about a problem around walls eating up floor space within the design.

This set features a few things:

* Flat stacking exterior walls
   * larger parts than standard OpenLock so you have fewer pieces to store and manage
   * so you can have a mega display piece and still have a very playable tabletop structure
   * you can also save the filament and just print the bottoms or just print the top parts of the walls to use on a battlemap
* Slide in interior walls
   * let's you re-arrange the layout on of an interior on a whim
   * allows for a sort of "fog of war" in terrain buildings
   * These include modular slots for doors so you can have a door or a mimic or the egress of your dreams
* All built to be modular and interchangeable so as the set grows it gets better (I haven't decided if I want to make it compatible with OpenLock sets and open the door to integration there but that could be an option!)

The consensus seems that some space doesn't need to be playable and while I agree I also want to make the set flexible for folks who want tight corridors (and Van Richtens and Mimics).

The solution I'm working on is to subdivide the grid into halves or thirds or quarters (tbd) and then to allow variable placement of the interior walls. You can see the screenshots and test prints in the gallery.

I've also included some photos of my other test prints and progress on this new set as well as a photo of the finished textured castle set. These old and new parts will be compatible with each other and enhancements will roll into the entire set.

A major part of this work is the underlying geometry nodes setup in Blender and some python scripts to support automatically building it all. If that sorta thing is your jam I share on my Patreon. I'm also running a Kickstarter for the new "Modular Barovia" set and sharing updates all over on that as well.

Like with my Castle set the goal is to share an untextured version of this terrain system for free and then have a textured version as a paid download. At the end of the day these projects are about learning and having fun so as long as that happens then I'm happy but if it ends up helping with my campaigns and others' campaigns then that's awesome - if somehow it helps offset the cost of filament and gas and groceries then it's amazing.
