I finally finished my big project! You can watch my workflow with this asset here!

Here is my Gumroad

thank you for watching!

Blender Guru said a traffic cone costs $3,600. So I built an Infinite Money Glitch (Procedural Cone Generator). Free download in comments.

I instanced these rooftiles to create this hexagon shaped roof, however i want it to be curved like the third and fourth image. I attempted to use a set position and a mask to do it, but that creates spacing between the tile rows

So I'm working on a system where you can take a model and have it generate a patchwork of pieces that can then be printed to make a mold. The pieces should not have any undercuts that would make removing the mold impossible. So right now I've generated patches (based on poison disk distributed surface points) where the normal is no more than 45 degrees from the seed and only contain all connected mesh pieces.

Ideally I want a) as few as possible segments b) the segments to be easily removable and c) something that takes curvature into account, so not having mold lines in deep regions that might make assembly difficult. Any suggestions of algorithms or papers to solutions would be helpful.

Apparently this is an NP-hard problem so I'm going to have to rely on some heuristics. This will probably be useful for more general cases involving other attributes or things like optimal 3d printing segments.
