I am an archviz freelancer with over 20 years of background in 3ds Max. I have been keeping an eye on Blender for a very long time and recently started using it for various tasks. I developed this modifier primarily to compare 3ds Max's RailClone plugin with Blender's Geometry Nodes. I was pleasantly surprised by how effective, customizable, and performant the Geometry Nodes are, and I have integrated ARCH TILER into my workflow.

new version V_065 Experimental opacity masks as "booleans" video: https://youtu.be/CRkuBf6aFQg

• One geometry node modifier consolidates all necessary parameters into a single tab.
  
• Fast - analize the tiles intersecting with borders and apply the cuts/booleans to these only, rest geometry is stored as instance.
• Choose your roof/wall/floor shape, add the geometry node modifier, and specify the tile collections. That's it! Now, you can fine-tune the parameters to achieve your desired result.
• Compatible with cutouts in the geometry, such as windows and doors.
• Precise and customizable offsets, scaling, rotation, and randomness.
• Works with some limitations on organic geometry. In edit mode, specify edge creases where the modifier splits the geometry for a more uniform distribution or set all rules manually in attribute mode.
• Automatically recognizes ridges, edges, bottom of the roof, and ridge valleys on common roof shapes.
• Shader parameters for UV adjustments, including tiling, random offsets, and rotation, if you export to other software you have to use its native randomization (for instance VRayUVWRandomizer)
• For export to other 3D software, down in the modifier parameters mark "realize instances", and apply the modifier. Now you are ready to export (I prefer using FBX or OBJ).
• Experimental opacity masks as "booleans" 100% instanced geometry allowing to use hi-res meshes for tiles and the count of the instances can go up to a few milions. Very fast execution times. From version V_065. See the details at the bottom of this page. 

geo node timings and instance numbers for rough idea, I am not sure how the timing works in blender, but here on 7950x the results are much faster, the slowest roof shows 29476 ms, but in reality it executes in 3s
