This is a collection of resources and software that I have found useful for 3D artists in one way or another. Some are free and some are paid resources.
Free to use cc0 or no attribution resources
Texturehaven.com – This site has excellent texture quality made from 3D scans. All cc0 and a historical theme.
cc0Textures.com – This site is a goldmine for anyone needing textures for most kind of scenes and architecture visualization.
cgbookcase.com – Same as above, a growing texture library of high quality cc0 textures.
sharetextures.com – Slightly newer site than the above ones but you can find some good textures here. Some textures requires you to join the patreon page for access.
Chocofur – Got high quality textures only requirement is to create an account to download them. They also have a nice 3D model collection under the cc0 license.
VirtualShade – Varying license between cc0 and cc-by. Even if the collection is quite small, whats there has excellent quality.
Texture.ninja – A large collection of image textures. only photos, no texture maps. But the size of the library makes it worth to check out.
Duion.com – This is a library of cc0 textures. Mostly photos that is taken to be used as textures, not properly prepared to be seamless or anything though so they need some work.

Pixabay.com – only cc0 images, larges library and fast growing
