Notes
- ¹ Use GeckoLib to run Blockbench animations in Minecraft mods
- ² Experimental feature
- ³ Only exports item display settings json (to control how items look in guis and hand)
- ⁴ Models that don't support unlimited cube sizes are restricted to only integers for cube sizes i.e. 0 1 2 etc.
- ⁵ Limited to multiples of 22.5° before 1.21.6
- ⁶ Optifine entities support expression based animations. Requires the CEM Template Loader Plugin to be able to edit and preview inside Blockbench. Documentation
