[1.12.2] Change texture for block at runtime

[MSpace-Dev]

I have a custom tile entity that can switch between 2 states, simply with bool = !bool

 

When this switch happens, I would like to change one of the texture references in the model.JSON to switch to another texture. How can I achieve this.
(There are multiple textures in the single model)

 

I noticed the furnace DOES NOT use blockstates for this. So, interested in how that was done. If not, I will end up using blockstates.

 

Thanks

Yes, I saw it's using 2 entirely different blocks.

 

Is that a recommended way to do it? Would I have to create a new Block class for every block where I want its texture to change at runtime?

Ah, alright, got it! Will stick to blockstates then
