[SOLVED] [1.16.1] Block texture visible in hand / inventory, but missing when placed in world.

[RubyNaxela]

Hello,
I've decided to update my old mod to 1.16.1 (actually I'm rewriting many things completely due to major changes in code in both Minecraft and Forge). But during the work, I encountered a really stupid problem. Like I said in the title, texture of every block is visible in any item slot, as well as in my hand. However when I place it down, the purple-black checker shows up. What can cause the problem?
 

Code details

The block is registered like this:

public static final RegistryObject<Block> SYLVITE_BLOCK = BLOCKS.register("sylvite_block", SylviteBlock::new);
public static final RegistryObject<Item> SYLVITE_BLOCK_ITEM = ITEMS.register("sylvite_block", () -> new BlockItem(SYLVITE_BLOCK.get()));

in registers:

public static final DeferredRegister<Item> ITEMS = DeferredRegister.create(ForgeRegistries.ITEMS, MoleculeForce.MODID);
public static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, MoleculeForce.MODID);

// Executed from main class
public static void init() {
  ITEMS.register(FMLJavaModLoadingContext.get().getModEventBus());
  BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus());
}

 

models/block/sylvite_block.json

{
  "parent": "block/cube_all",
  "textures": {
    "all": "[modid]:blocks/sylvite_block"
  }
}

models/item/sylvite_block.json

{
  "parent": "[modid]:block/sylvite_block"
}

blockstates/sylvite_block.json

{
  "variants": {
    "normal": { "model": "[modid]:sylvite_block" }
  }
}

* exists and is valid if it works for blockitem *

Thanks in advance!

@diesieben07 danke schön. I think you help the best way possible. You don't serve ready solution but make me do some research on my own with a brief couple of words. I appreciate that.
But anyway, back to the topic. The problem was indeed with loading the model, but not with the model itself. My blockstate file looked like this:

{
  "variants": {
    "normal": { "model": "[modid]:sylvite_block" }
  }
}

"normal" is not a recognized blockstate anymore and has to be empty. Furthermore, I addressed the model file wrongly. After corrections, it looks like this:

{
  "variants": {
    "": { "model": "[modid]:block/sylvite_block" }
  }
}

And now it works correctly.
