This tutorial shows you how to make Material, Object, and World Presets in Blender, allowing you to quickly assemble scenes with your own personal default assets in a convenient interface.

1. Create a Material Asset directory on your hard drive, a directory you plan on putting all your material assets.
2. First make the material you want to make a preset of in a brand new Blender file.
3. Render out a nice representative thumbnail for the material, you'll use this later and associate it with your asset. Save it to your material asset directory.
   
4. In the Material Properties Tab, right click the material name and choose "Mark as Asset"
5. Give the Material a good name.
   
6. Save your blender file to your material asset directory.
7. Go to your preferences and the "Asset Libraries" section, add this directory. Choose the Import Method: Link means if you change the original asset, any instance of this asset in any file will automatically update. Append means you get a copy of the asset, but changing the original asset will not update the copy. Pack is like Link, except if you hand the file off to someone else who doesn't have the original asset, it will revert to a copy of the asset instead of saying it can't find the original asset.
   
8. Add a new Editor window to your blender interface, change it to "Asset Browser"
9. You should see your asset in the browser. Notice you can see a subset of your assets by changing "All Libraries" to any specific library, such as the directory you placed your material asset inside.
   
10. Click on the asset and pull out the properties via the little arrow on the upper right.
11. Under Preview, click "Load Custom Preview" and load the thumbnail you saved in step 3.
12. Now drag the material asset onto an object, now that object has that material.
    

1. Create an Object Asset directory on your hard drive, a directory you plan on putting all your object assets.
   
2. First make the object you want to make a preset of in a brand new Blender file.
3. Render out a nice representative thumbnail for the object, you'll use this later and associate it with your asset. Save it to your object asset directory.
   
4. In the Outliner, right click the object name and choose "Mark as Asset". Notice how the object in your outliner now has a little asset icon beside it. This works for individual objects, or groups of object if they're in a collection (right click on the collection name)
   
5. Give the Object or Collection a good name.
6. Save your blender file to your Object asset directory.
7. Go to your preferences and the "Asset Libraries" section, add this directory. Choose the Import Method: Link means if you change the original asset, any instance of this asset in any file will automatically update. Append means you get a copy of the asset, but changing the original asset will not update the copy. Pack is like Link, except if you hand the file off to someone else who doesn't have the original asset, it will revert to a copy of the asset instead of saying it can't find the original asset.

9. You should see your asset in the browser. Notice you can see a subset of your assets by changing "All Libraries" to any specific library, such as the directory you placed your object asset inside.
   
10. Click on the asset and pull out the properties via the little arrow on the upper right.
11. Under Preview, click "Load Custom Preview" and load the thumbnail you saved in step 3.
12. Now drag the object asset into your 3d scene, now your object is in the scene. Note how objects can snap to other objects if you drag the asset onto an object instead of the grid.

1. Create an Environment Asset directory on your hard drive, a directory you plan on putting all your HDRi world environments.
   
2. First add your hdri to the world tab of a brand new Blender file.
3. Render out a nice representative thumbnail for the environment, you'll use this later and associate it with your asset. Save it to your environment asset directory.
   
4. In the World Properties Tab, right click the word "World" and choose "Mark as Asset"
5. Give the World a good name.
6. Save your blender file to your environment asset directory.
7. Go to your preferences and the "Asset Libraries" section, add this directory. Choose the Import Method: Link means if you change the original asset, any instance of this asset in any file will automatically update. Append means you get a copy of the asset, but changing the original asset will not update the copy. Pack is like Link, except if you hand the file off to someone else who doesn't have the original asset, it will revert to a copy of the asset instead of saying it can't find the original asset.

10. Click on the asset and pull out the properties via the little arrow on the upper right.
11. Under Preview, click "Load Custom Preview" and load the thumbnail you saved in step 3.
12. Now drag the world asset into your view, now the env uses this hdri.
