TL;DR: copyright issues
A copyright issue is any question or dispute about who owns a creative work and who may copy, change or sell it. For 3D artists the most common ones are: someone reposts or resells your model, you use a texture, brand or character you had no right to use, a client and you disagree about who owns the files, a licence is misread, and, since 2023, AI companies training on models you published.
Most copyright issues are settled without a court: with proof, a clear message, a platform takedown or a cease and desist letter. This guide lists the 12 issues Blender artists run into most, what the law says about each, what changed in 2026, and the steps to prevent and solve them.
Most copyright issues are won or lost on proof. BlendedBoris is a free plugin for Blender that records your 3D model on the blockchain and gives you a lifetime ownership certificate. It creates a digital fingerprint that links the model to you, so when your work is reposted, resold or claimed by someone else, you can show a dated record of every version you made and attach it to a takedown or cease and desist letter.
