[Bf-committers] Blender Addons Policy

Tue Jun 22 14:57:11 CEST 2021

Hi Lechu,

Sorry, I mix up addons. To my knowledge your addon was not in the 
'commercial addon' category then. Blenderkit and Sketchab are the only 
two currently.

The discussion is going astray; please don't take it personal but look 
at this as a way to create an equal playfield for everyone.

Sketchfab, for example, offers a half million CC0 models. And there's 
3dmodelhaven, they are seriously creating a huge CC0 library as well. I 
bet there are more.

I think we're better off by only defaulting to services that are part of 
blender.org. On blender.org we do not want to implement our own models 
repository, so we're not competing or creating unfair advantages for 
independent websites. (*)

Then there's the safety and security issue for Blender. If people 
download the software and enable add-ons, they should have the same 
quality backup as for any Blender feature.

-Ton-

(*) I would only consider to host a massive CC0 asset collection on 
blender.org if such a public service is being endangered, for example 
because of something evil like a Content ID for 3d  models.
