Parents and textures
A parent such as cube_all or cube_column supplies standard geometry. Texture variables point that parent to your namespaced PNG assets.

Minecraft Block Model Generator
Starter Java block-model JSON using common vanilla parents. You still need a matching blockstate file to wire it to a block.
Model
Pack location
assets/<namespace>/models/block/custom_block.json
This only writes the model. Add a blockstate JSON under assets/<namespace>/blockstates/ so the game knows when to use it. Textures must exist under assets/<namespace>/textures/... matching the paths above.
Generated custom_block.json
{
"parent": "minecraft:block/cube_all",
"ambientocclusion": true,
"textures": {
"all": "my_pack:block/custom_block",
"particle": "my_pack:block/custom_block"

Minecraft Block Model JSON Generator
Create a basic Java block model using common vanilla parents and texture references. Download the JSON and place it in your resource-pack models/block folder.
Blockstates still matter
A model alone does not connect itself to an in-game block. Add a matching blockstate JSON that selects this model for the required properties and variants.
Quick questions
Can it build arbitrary cuboids?
This first version focuses on reliable vanilla parent models rather than a full 3D element editor.
Does it create blockstate JSON?
Not yet. The page explains the additional file needed.

If something feels wrong, a Minecraft version is missing, the wording is confusing, or you have a better workflow idea, send it over. Real player feedback is how these tools get sharper.
