Importing Sprites
Currently, only Portable Network Graphics (PNG) images are supported. Other image types will be added in the future.
Add image file to project
Using a file explorer, copy an image to the Textures folder in your project.
Create sprite asset
Navigate to the editor menu bar and click Asset > Asset Import. Once the asset import window is open, click Browse and select the image file previously copied. Next, click Import to create the sprite asset. An asset with the same name as the image with a .planarsprite extension will be created in that directory.
