• TexTools
  • I find TexTools practically indispensable for doing UVs. Every 3D Blender artist should have this addon.
• Project-Timer
• Outline Helper
  • This doesn’t do anything special other than automating setting up inverted hull outlines. Immense timesaver
• Apply Shape Key to Basis
  • This is a ported feature from CATS that works on 3.6+, immensely useful.
• Sculpt Mask Tools [Gumroad] [Github]
  • Main feature I use is saving sculpt masks to vertex groups
• SKkeeper
  • Apply modifiers to meshes with shape keys
• Vertex Group Utils
  • So many features..
• Robust Weight Transfer
  • This is a tool everyone should have in their toolkit, it doesn’t replace the vanilla method of weight transfer! It works a bit differently in how it interprets weights, it’s amazing.

Included Blender Addons

All of these were included in blender before 4.2, otherwise you can find them on https://extensions.blender.org/add-ons/

• LoopTools
  • Has a LOT of functions, but I primarily only use the circle tool.
• AddCurve: Extra Objects
• AddMesh: Extra Objects

I like these, but they’re not as important/good as the ones above

• BoneDynamics (Free)
  • If you take this addon at face value, it’s honestly not great. HOWEVER! If you only use it to automate setting up your bone-soft body constraints, it’s amazing. Expecting this addon to work out of the box to get you physbone/dynamic bone style bone physics is a recipe for disappointment basically x)
• Animation Retargeting
  • Extremely clear user interface, fairly simple, I’ve found it’s easiest to use for retargeting Mixamo rigs
