I want to get the model out of the json file and render it, I could do a single block for each part of the model, but that's not comfortable.

private ModelResourceLocation modellocation = new ModelResourceLocation("allyouneed:splinklertop","inventory");
    private IBakedModel model = Minecraft.getInstance().getModelManager().getModel(modellocation).getBakedModel();

I kind of figured out how to get it, but how to render it? 

Hi

Have a look at this example project

https://github.com/TheGreyGhost/MinecraftByExample

mbe04 does something similar

 

Where do you want to render it?  In a TileEntityRenderer, or an Entity, or somewhere else?

 

Cheers

Check net.minecraft.client.renderer.tileentity.PistonTileEntityRenderer 

It should help

I am render TileEntity. Everything you wrote, it takes the model from the block, not directly from JSON.
