Introducing Texture Resolutions for Models, Materials and HDRs
We are glad to introduce the Texture Resolutions feature in Blender 2.92. If you have a small GPU memory or want to create much larger scenes, this is the feature you’ve been waiting for. Now, you can work much faster with lighter scenes in Blender and swap to higher quality only if you need to. Go ahead and try it in Blender 2.92 beta.
All textured assets with original higher resolutions now have lower resolutions generated. This saves memory, speeds up all interactions and also helps you to render bigger scenes.
All assets in BlenderKit are uploaded in the highest possible resolution - usually with 4K images and sometimes more. So, if you have a PBR material, it may be as large as 5x4K images, which is huge - 80 Megapixels with 80 million of them usually stored in 4 values each (RGBA color channels). This adds up to 320 megabytes of data!
That’s why we now generate lower versions of these assets, in which we reduce not only the size of the images, but also the number of channels when needed. The images are also converted from .png to .jpg when needed. Thanks to this, the download size will be reduced tremendously, while the quality of the assets stays very similar or the same in your viewport.
Moreover, render time and especially memory efficiency will be improved manifoldly. If you use 1k textures for your scene (which is frequently enough for most assets), you are using 16x less memory space, while the size of the assets is often even smaller (up to 100x smaller).
Resolutions can be swapped with the command 'Replace asset resolution' in the Selected model panel or in the Asset bar.
The Resolutions feature is currently available for Models, Materials and HDRs. In the future, it will be introduced for Scenes as well.

We are always busy working on our add-on, and we have a new release of our add-on for you! Know that we've rewritten a huge part of the add-on to make it work great for everyone.
We created the first of the BlenderKit artists interviews with Julio Sillet, who has uploaded many great materials to our website.
Literally every area you step in Blender requires you to learn a lot of new tools and information, and that's why we implemented several 'shortcuts' for convenience and speed.
Stones, rocks, pieces of wood can be sometimes photoscanned. But plants are still a domain of hard-core modeling. This really takes time, skill and precision, and a lot of observation what "natural" really means.
We are trying to help you, blenderheads, to save your time while achieving best results possible. Wallpaper textures can really boost interior renders, but do you already have those on your hard drive?
As a late Christmas gift, we are releasing our BlenderKit mascot kitten for free. Now, you can make any scene insta-cute! The kitten is poseable and can be animated (by now 2.79 only, because of a hair-import bug in 2.8 beta).
BlenderKit introduces add-on for Blender 2.8. While there are still many changes in Blender happening, which may cause the add-on will work today and not tomorrow, the add-on should be mostly working fine, and we try to keep the new version updated with the latest Blender builds.
We are happy to announce the release of something we've been working on for a long time.
BlenderKit is a new online platform made for Blender users, creators, and developers. We hope to bring a new momentum into the open source world by introducing several innovations we've been working on.
