This Add-on for Blender includes several curve generators/kitbashing tools. It has tons of options but is super easy to use at the same time. And we're still adding more!

https://blendermarket.com/products/paranormal-toon-shader

ParaNormal Toon Shader is a procedural normal parallelization shader, an innovative NPR shading solution that allows a fully light-driven workflow and full compatibility with both EEVEE and Cycles, including GPU rendering.  Full support for the real lighting in your scene eliminates manual adjustments to materials, making it a breeze to achieve stunning toon rendering with subtle gradients, detailed shadows, and dramatic lighting.  Make your toon renders stand out like never before with a unique look inspired by digitally colored comic books and anime, while using the standard Blender workflow you already know.

The addon is free! But you can pay it to support development. <3

Gumroad - Motion Node for Blender

This Blender Motion Node pack is inspired by the MoGraph C4D approach, its simplicity and flexibility. Motion nodes are small building blocks that I use to create motion graphics every day. They include generators, selection, fields, deformers and others. Motion Nodes are not an all-in-one tool, I tried to maintain the flexibility of the geonode blender while removing routine actions. For this reason, you will need basic knowledge of geonodes, which you can highlight from example files or other lessons.

Whether it's for an old attic, a dark cave or just a colorful nature scene - Insect Swarm systems can help you breathe life into your scene in no time. You want crawling insects, flying swarms or even centipedes? These simulation node systems contain everything you need.  With just a few clicks, the insects move autonomously or guided over the surface you choose or fly through the air! You can also determine which objects the insects are attracted to and which they avoid. If you need them to go somewhere specific, you can use curves to tell them where to go! Each insect gets simulated individually!   Plus, with the purchase of this system, you'll get 21 different animated low-poly insects that have been optimized for the systems, so you can have thousands of insects running and flying around your scene at once!  That's not all! The systems as well as the insects are packed into one organized asset file, that lets you drag and drop whatever you need at any time into any project!

Clay Doh uses Principled BSDF, allowing flexible workflow and physically correct shading. This ensures that all assets will look great in any kind of lighting.

No UV unwrapping or texturing needed for non-animated models

Make all kinds of clay with a single master node

I created this wonderful kitbash set for concept artists and people who would like to do something interesting and cool. These are low-poly and medium-poly assets.

Configured for Blender assets browser, Works incredibly well with Megascans!, 60+ elements

Addon for Blender 4.2+, that will show retopology overlay on top of your mesh

Keymesh is one of the most popular and iconic Blender add-ons by Pablo Dobarro, one of the creators of modern Sculpt Mode. It lets you create stop-motion animations inside Blender by letting you animate mesh objects frame-by-frame. You can sculpt animation, or model it, frame-by-frame. You can animate UV Maps, attributes, color attributes (vertex paint), and almost everything in a very traditional way.

https://blendermarket.com/products/retopoflow

RetopoFlow is a comprehensive retopology tool designed for Blender, enabling users to efficiently generate custom, clean, mid or low poly meshes over high resolution sculpts. This unique mode not only provides additional information about the models beyond Blender's default capabilities, allowing for more effective tool usage compared to other options on the market, but also offers a more user-friendly display of the geometry. Currently, RetopoFlow mode stands as the sole method in Blender to showcase low poly geometry seamlessly overlaid on a high poly mesh without encountering any overlap, distortion, or depth sorting challenges.

Ossim v1.5.0

Ossim is a simulation baking tool for Blender that generates an armature and skinned geometry based on rigid body physics simulation to use in game engines and realtime applications such as Unreal Engine 4 or Unity3d and many others.

BlenderMarket - RetopoFlow Retopology Toolkit For Blender v4.0.2 Alpha 

https://blendermarket.com/products/retopoflow

RetopoFlow is a full retopology mode for Blender that helps make quick work of creating custom, clean, mid or low poly meshes on top of high resolution sculpts.

The separate mode helps us not only get more information about the models than Blender can give by default (so our tools can work more effectively than anything else available today), but also to display the geometry in a more helpful manner. RetopoFlow mode’s custom mesh rendering is currently the only way in Blender to see low poly geometry cleanly overlaid on a high poly mesh without overlap, distortion, or depth sorting issues

Marker Manager is a Blender addon that provides and extend timeline markers capabilities with extra features

The Timeline Marker in Blender is very basic, it has so much more potential and it’s this addon’s wish to expand its possibilities to make it more useful.

A simple but flexible painting system for non-photo-realistic-rendering in Blender
