From South Africa, the new Poly Haven. A library website of free CC-Zero Blender assets with, at present, what appears to be some quality-control. A test of a small oil-can gave me an open public download (no sign-up needed). The polished and roomy new site seems to be from a small group of young Blender enthusiasts, who plan to run on a mix of crowdfunding and ads. It’s crowdfunding now.
Opening my test file failed in Blender 2.76, but succeeded in 2.83. Automatic Blender to Poser conversion then succeeded nicely, and the can was inside Poser in seconds and looking good.
