For a simple block, I use "formact_version" 1.19.10 and don't add geometry, just texture. In "resource_packs/blocks.json you add the texture.
An example from my files:
block.json↓
{
"format_version": "1.19.10",
"minecraft:block": {
"description": {
"identifier": "t3:araucoplanks"
},
"components": {
"tag:wood": {},
"minecraft:display_name": "araucoplanks",
"minecraft:flammable": {
"burn_odds": 20,
"flame_odds": 5
},
"minecraft:creative_category": {
"category": "construction",
"group": "itemGroup.name.planks"
},
"minecraft:loot": "loot_tables/blocks/arauco/araucoplanks.json",
"minecraft:destroy_time": 1,
"minecraft:light_dampening": 0,
"minecraft:material_instances": {
"*": {
"render_method": "opaque",
"texture": "araucoplanks",
"ambient_occlusion": false,
"face_dimming": true
}
}
},
"events": {}
}
}
resource_packs/blocks.json↓
"t3:araucoplanks": {
"sound": "wood",
"textures": "araucoplanks"
},
resource_packs/textures/terrain_texture↓
"araucoplanks": {
"textures": {
"variations": [
{ "path": "textures/blocks/araucoplanks" },
{ "path": "textures/blocks/araucoplanks2" },
{ "path": "textures/blocks/araucoplanks3" },
{ "path": "textures/blocks/araucoplanks4"}
]}},
Hope I helped.
