Installing Assets from the Downloaded Flowasset Files
If you have downloaded the .flowasset files from polyspaace.com, you can easily install all of them within single operation into the selected Flow library, just from the panel level in the main Blender window. Simply press Install Assets button and go to the directory with your downloaded .flowasset files, select all of them by pressing A on your keyboard, and press Install button.
The assets will be automatically installed and categorized within the selected Flow library, based on the data included in the .flowasset files. Also the assets will be categorized in the Blender Asset Browser, and the required lines will be automatically appended into the blender_assets.cats file located in your Flow library.
