Blender is a very cool program that does a ton of things very well. One of the things it does not do very well is typography (for example, even basic typographical features like kerning are not supported).
That’s why ST2 exists: an add-on to help you set 3D type with the full range of modern typographical features — among them OpenType stylistics sets, ligatures, and, yes, kerning. ST2 also provides support for typesetting all kinds of languages (not just Latin-based ones).
Also Blender does not have support for variable fonts; this add-on adds support for those, along with support for keyframing variable font axes. (This is a little experimental though, as Blender will sometimes crash if you change meshes too often, particularly on macOS. To get around this, the ST2 add-on provides an "export" mechanism that will create a new object for every frame of your animation, and then show that instance on the appropriate frame only.)
Using a Blender version 3.0 or later, grab the latest release from the releases page, download the zip, then open Blender, open the Blender preferences, head to "Add-ons," then hit "Install..." in the top-bar and navigate to the ST2 zip you download and hit "Install Add-on" — this should bring up ST2 in the Add-ons view (if it doesn't, try searching for "ST2"); once you see it listed with a checkbox, enable the extension by hitting the checkbox.
N.B. On Windows, the first time you use the ST2 addon, you’ll need to run Blender as administrator (i.e. right-click and Run as Administrator).
Make a file config.py at the root of this directory, with one line setting a BLENDER variable to the specific Blender app/version you'd like to use for development, i.e.:
BLENDER = "~/Desktop/Blenders/Blender3.2.1.app"Then you can run the install script:
python3.10 scripts/install.py
That should place a symlink to ST2 in the correct addons folder.
