[1.16.5] Help updating entity model code? Or is there a JSON alternative?

[SapphireSky]

I'm trying to make a custom model for a piece of armour, but am having trouble.

The code that Blockbench exports either uses old mappings, the unofficial (or unofficial?) mappings (my project is using whatever is default), or both. I can't tell.

.

I tried updating the exported code to what I assume is the proper equivalent in my case, but ModelRenderer::setRotationPoint(x,y,z) doesn't seem to have any alternative.

The closest thing I can see that affects rotations at all is ModelRenderer::translateAndRotate(matrixstack), but I can't figure out how to use that, much less if that's even the right option to use.

.

This is the exported code vs my attempt at fixing it, in case I did something else wrong as well, I'm going off older tutorials and Google here..:

Exported model class with wrong mappings:

I don't suppose there's any way to make this so much less work and just use standard JSON item models as armour instead...?

If you're translating individual files, there's not much you can do about it. You could use the updateMappings gradlew task, but that's better for large batches of code. As for JSON item models, that is a much more complicated issue that involves layers and custom transform types. While still possible, the tradeoff isn't really worth it.
