https://blendermarket.com/products/simplebake---simple-pbr-and-other-baking-in-blender-2

SimpleBake is the definitive baking solution for Blender. In short, it allows you to simply bake PBR and other textures.  Blender provides a very powerful way to create complex PBR materials by using nodes. However, what should be a simple process of baking and exporting these materials for use with other software or systems (Substance Painter, Second Life, Sketchfab, Unity etc.) is surprisingly difficult.

https://blendermarket.com/products/disassembler

I have created an addon that allows you to flatten and sort the components of, for example, a cabinet or anything else. The purpose of this addon is to make it easier to turn something designed in Blender into a physical object. Up until now, I would draw something (like a cabinet) in Blender and then manually flatten everything to fit it onto a sheet of wood. This process is time-consuming and prone to errors. The addon cannot 'nest' but can assist in the process.  Often, to estimate the cost of a product, it's helpful to know how much wood is required and the total surface area of everything combined. This addon can calculate that for you. Additionally, it can generate DXF files for the components that can be exported to a CAD program.

https://blendermarket.com/products/djh-geometry-node-assets

My Geometry Node Assets are a collection of modifiers/custom nodes for Blender that you can import as an asset library.

It is my opinion that it is easy for a GeoNode setup to try and do too much.  My approach to making modifiers is to think of them as tools in a tool box, and while working on you scene you will often use several tools in combination rather than one 'super-tool.'  Many of my modifiers are simple enough to allow for many generic combinations, while others are individual pieces of a modular set and were specifically built to be used in a stack.
