Hi!

Could anyone tell me how I can use Blender models as models for entities? (in this case a custom minecart)
Around I find only old tutorials for 1.10 or earlier.

What format is the model in?

The file has .obj as extension, extracted from blender

Then if you don't expect any animation, you can just use the model loader system. Supply it in some location and create a json model with the loader forge:obj, then you would specify the model location and material. You can look at the omnibus for an example. Next, you'll want to go into the ModelRegistryEvent and call ModelLoader#addSpecialModel. You can then just render the baked model at a specific location similar to how BlockModelRenderer or ItemRenderer does it, adjust it for places such as needing a double for the location or just use the MatrixStack to offset the value.

 

If you want animation, then you are using the wrong export type. You'll probably need to make the model loader for that on your own.
