RenderType endPortal does not render Custom Block with End Portal shader

[Guest]

I was wondering if all you needed to create a block that looked like the end portal (without functionality) was this line of code: 

ItemBlockRenderTypes.setRenderLayer(ThingamajigsBlocks.END_PORTAL_DECO.get(), RenderType.endPortal());

 

This line of code was in the setupClient() method with every other block's renderType setup.

 

This is the line of code for the custom block in the Block Registry class:

public static final RegistryObject<Block> END_PORTAL_DECO = registerBlock("end_portal_deco", () -> new Block(BlockBehaviour.Properties.of(Material.STONE).strength(10f,100f).requiresCorrectToolForDrops().sound(SoundType.STONE)), ThingamajigsCreativeTab.ALL_ITEMS_TAB);

 

But it was just an invisible block, everything else about it worked however (model, item, recipe, loot_table).

I looked at vanilla code and it didn't seem like I was missing a step. Did I forget a crucial step somewhere to make the block render like the end portal?
