I wanted to share something that helped me when I started creating custom blocks and items.
A lot of new modders get stuck because of tiny JSON syntax mistakes in blockstate or model files.

A few simple tips:

• Always validate your JSON using an online validator

• Make sure your paths match exactly (Forge is case-sensitive)

• Check that all textures are referenced from the correct namespace

• If your model is invisible, 90% of the time it’s a missing comma or wrong folder name

Hopefully this helps someone avoid an hour of debugging like it did for me.

It takes some setting up and figuring out, but using data generators will ensure there are no json errors.
