Skatter objects on invisible layers

Im wondering what the best method is for when you use a model which isnt created by skatter. For a example bush where the inner part the is the “Host” for the instances is on a different layer. Ive noticed that the parts not created by skatter dont get rendered than.

I’m not sure I undestand your question, can you give me an example?

Maybe a sketch to go along with the question

I think i got it figured out. I was some sort of “mis” -modelling. A part of the model base wasnt set to 0level so by hidding the layer would also cause the base mesh to hide.
