 ## Todo
 
+* Fix the item model lol, broke it with the new system (might need a ModelLoadingRegistry registerVariantProvider as a last resort)
 * Re-generalize the model system (I removed a layer of indirection while rewriting it, so it's just slopes now)
-* See what I can do about using the vanilla rotation system (`ModelBakeSettings.getRotation`) instead of manually rotating the `Mesh`
+* Upside-down slopes would be nice...
-  * A simplification of the mesh system would *definitely* reduce the friction of adding new meshes (see all the `paintXxx` stuff in `SlopeMeshTransformer`, it's fairly ugly)
+* Pass UVs as part of the mesh and retexture them at runtime too
-  * Upside-down slopes would be nice...
-* (if i may): Packages-ish "retexturing" of json blockmodels
 
 ## Notes for addon developers
 
 To create your block, instantiate or extend `TemplateBlock`. Pass your `Block.Settings` through `TemplateBlock.configureSettings` to wire up the "click for glowstone" feature. Create an `ItemBlock` as normal, and create a `BlockEntityType` by instantiating or extending `TemplateEntity`.
 
-Next, wire up the custom model. im going to refactor this in like 5 seconds so im not documenting it >:).
+Next, wire up the custom model todo document this, it's easy
