It's hard to say without more details, but a couple guesses: 1. Have you adjusted to cage to make sure the floaters fit inside it? 2. Are the floaters in their own bake group? If so they won't have any low poly meshes to bake onto, they need to be in the bake group with the respective areas that they're associated with
hi, the cage has been set to cover the new floaters, and i attached them to the current hi poly substance painter has given me the error "mesh bitangents are invalid" i dont know what that means or if it effects marmoset too?
