Baking position

Check your model’s positon

When you bake the position texture, it’s important the model is in the same position as it’ll be in-game, as many generators and effects use those maps to react, and the result will be wrongly driven by that Texture map. If you bake the low-res model in a bad rotation position you’ll need to repositionate your model, re-import into Substance, then re-bake the Position maps.
