Introduction
Hi!
Moved tools and add-ons to separate wiki-thread: WIKI - Free Blender-related tools and addons
After some short discord discussion I’m creating a post for gathering and maintaining a list of free resources that we can use while working with Blender.
Post resources below and I will try to categorize it and maintain the list. If you find inaccuracies in my descriptions - please point them out and @ mention me. Edit: or you can edit this post! Seems that it’s possible to make a post of “wiki” type 
Also, be sure to check the license of a given site/file before using them in your projects.
Textures
- https://3dtextures.me/ - CC0 textures, some have substance source files
- https://cc0textures.com/ - CC0 textures and some contain substance source files
- https://www.cgbookcase.com/ - CC0 textures
- https://www.sharetextures.com/ - public domain textures, but with some resources limited to patreons
- https://polyhaven.com/ - CC0 textures and other CC0 assets (previously https://texturehaven.com/ )
- https://3dassets.one/ - search engine for some of the above sources.
- https://www.texturecan.com/ - some free textures
Materials
- Community Material Pack CC0 material pack from Curtis Holt community
- https://blendermarket.com/products/sanctus-library-addon---procedural-shaders-collection-for-blender/ - there is a free version with 18 procedural materials
- https://blender-materials.org/ - "Open Material Repository - a library of material files for Blender 3D provided under public domain "
- https://www.youtube.com/playlist?list=PLsGl9GczcgBs6TtApKKK-L_0Nm6fovNPk - Youtube playlist: hundreds of free procedural material tutorials (one video per material). The most recent seem to use Blender 2.8, though I expect it mostly works in Blender 3.whatever too (though I know some nodes changed names).
Alphas
- ZBrush - The World's Leading Digital Sculpting Solution - Pixologic’s Alpha Library. At the time of making this link they are free to use, even for commercial purposes.
Models
- Blender free base human meshes bundle - From the makers of Blender
- sketchfab.com - some free and paid 3D models. Needs account to download.
- https://polyhaven.com/ - some CC0 models (patreon supported) (previously known as https://3dmodelhaven.com/)
- https://thebasemesh.com/ - From the site: “250+ Base Meshes. Updated weekly. ## 100% free. CCO license.” (I’ve downloaded a few and it seems that base meshes come in obj and fbx formats)
- Quaternius • Free Game Assets - A lot of CC0 low poly (style) models. Useful for all kinds of things, not only games.
HDRI
- https://polyhaven.com/ - CC0 HDRIs, in my eye of very high quality (used in some of the courses), previously known as https://hdrihaven.com/
- http://noemotionhdrs.net/ - some CC-BY-ND HDRIs
- https://www.ihdri.com/
General
- SheepIt Render Farm - Free render farm for Blender
- https://www.blendswap.com/ - a place to exchange Blender related materials. Mostly shared on CC license variants. Needs account to download.
- Smithsonian Open Access | Smithsonian Institution - Smithsonian Open Access, mostly textures and 3d models
- https://ieslibrary.com/en/home - large collection of free IES lighting profiles
Blueprints
- https://www.dimensions.com/ - Dimensions is an ongoing reference database of dimensioned drawings documenting the standard measurements and sizes of the everyday objects and spaces that make up our world.
- https://www.the-blueprints.com/ - Marc’s reaction sums it nicely “picks jaw up off the floor and then posts the link Need a free blue print for almost anything. Check out the above”. Note, only some blueprints are free (vector ones are paid). Requires creating account to download full sized images.
- https://print-graph-paper.com/ - Here you will find an assortment of free printable online graph paper.
Geometry Nodes
- https://3d-wolf.com/products/assets/generators/ - A few CC0 “generators” for various things including lightning, rope bridges, and chains.
. I’ve used them with unreal previously. It’s important to have if you aim for realism in interior scenes (e.g., archviz).
