Topic category: Feature requests and ideas for MCreator
What about, alongside have an option to create a 'Block', also have an option to create a 'Special Block'? You'd be presented with a list of different block types, and then you'll be asked to add the amount of textures asked for and the size of the texture.
This would support block types such as:
Slabs, Stairs, Glass Panes/Iron Bars, Doors, Trap Doors, Fences, Fence Gates, and Walls.
They would act exactly like their vanilla counterparts, just with different textures. All or most combatible of the configs available when creating a normal block would be available here as well.
I'm not an expert, but I don't see how it would be so difficult to use code that is already in the game.
