Isometric Renders allows you to take isometric screenshots, or rather, create renders of game objects like parts of world, blocks, items and entities. These are automatically keyed to have a transparent background and you can adjust scale, positioning and many more options right in-game in a fancy gui. This was designed with modded wikis or similar documentation in mind, should be easy to use and mostly pretty performant.
In-Depth documentation is available on the wiki
