https://blendermarket.com/products/qol-gridcut

The GridCut addon is an elegant one-click solution for mesh slicing the current active object.    Many modifiers require meshes to have a certain polygon density, and the subdivide modifier very often, for many reasons, doesn't do the trick. Subdivide tends to cause gluts of tiny polygons, stretched polygons, and in the case of nGons, often bizarre tesselation. This is where GridCut comes in handy !  It evenly distributes cuts regardless of topology in any or all axes.

Quickly create an infinite variety of unique 3D objects with the Shape Generator.   These objects can then be used by digital artists as a source of inspiration, a starting point for a new design, or to quickly provide background details.  Due to its popularity and support, the Shape Generator has evolved into an extensive tool that features customizable presets, random transformation, automatic UV mapping, and even animation.

https://blendermarket.com/products/k-cycles

K-Cycles is a highly optimized custom build of Cycles-X render engine, ultra lighting, post FX, ultra denoiser and realtime viewport lighting and effects for Blender. It is fully compatible with Cycles and designed for Nvidia GPUs.

https://blendermarket.com/products/render-time-calculator

This is an addon for Blender that let's you calculate the amount of time needed to render an entire animation.  You have to input the time it takes to render 1 frame or 3 in advanced mode and the addon will calculate the time needed.

https://blendermarket.com/products/conform-object

For any 3D modeler that needs to project objects onto another object surface in one direction.

The add-on handles the complexity of doing this for you in a non-destructive way, using the source object's location and orientation to project it onto the target object's surface.

https://blendermarket.com/products/anime-hair-maker

 The common process of making anime alike hair is to make a hair strand and duplicate all over the head. This addon offers additional ways to populate hair strands, for example, it utilizes blender new hair system to sculpt, plant hairs with modal operator, directly draw bezier hairs as well as convert from legacy particle hairs. In the mean time, bevel and taper profiles are taken care of with a click of button. Curve manipulating also made easy with included curve tools.

The FLIP Fluids addon is a tool that helps you set up, run, and render liquid simulation effects all within Blender! Our custom built fluid engine is based around the popular FLIP simulation technique that is also found in many other professional liquid simulation tools. The FLIP Fluids engine has been in constant development since 2016 with a large focus on tightly integrating the simulator into Blender as an addon. It just feels like a native Blender tool!

Blender CAD Tools is a set of add-ons for Blender that make CAD designing with Blender even more enjoyable.

https://blendermarket.com/products/construction-lines

Construction Lines is a tool for accurate CAD style modelling. Build snappable guide points and edges, draw lines and primitive shapes in place, automatically create faces in closed geometry, precisely move, duplicate and rotate geometry around a scene and cut-through meshes with extrude.  Guide edges and points allow for a construction workflow where guides are set and models are then constructed within these guides. The guides won't interfere with model geometry and can be toggled off and on when required. Guide edges will disappear when working outside of Construction Lines and neither Guide Edges nor Guide Points will be rendered.

https://blendermarket.com/products/auto-rig-pro

Auto-Rig Pro is an addon for Blender to rig characters, retarget animations, and provide Fbx/Gltf export, with presets for Unity, Unreal Engine, Godot. First developed as my own in-house rigging tool, i've released it a few years ago and it expanded quickly thanks to great support from the community!

https://blendermarket.com/products/gaffer-light-manager

Gaffer is a Blender add-on that helps you light your scenes by presenting all the right settings in convenient panels for quick access and experimentation.  As a lighting artist, I created this add-on to help me with my everyday work. Not only did it speed up my lighting workflow, but it meant I could focus on creating better lighting without getting distracted searching for buttons.

ND (Non-Destructive) is a Blender add-on designed to revolutionize 3D modeling workflows by offering a range of tools and operations tailored for non-destructive modeling techniques. With ND, users can enjoy enhanced flexibility and efficiency in creating 3D models, particularly for hard-surface forms.  The key feature of ND is its emphasis on non-destructive editing, allowing users to adjust parameters and make changes to their models quickly without the need for manual poly-modeling. This approach is particularly beneficial for iterative design processes, as it enables artists to experiment with different variations and refine their models with ease.  One of the primary methods employed by ND is the extensive use of modifiers, which play a central role in enabling a flexible modeling workflow. These modifiers allow users to apply various transformations and effects to their models without permanently altering the underlying geometry. This means that changes can be made at any point in the modeling process, providing greater creative freedom and control.  Overall, ND offers a comprehensive toolkit for non-destructive 3D modeling in Blender, empowering artists to streamline their workflows, iterate more efficiently, and achieve high-quality results with ease. Whether working on personal projects or professional productions, ND provides the tools needed to take modeling workflows to the next level.
