My Kaiju mod problem. Do model Attachments in entities have a node limit too?

So I have this massive overly detailed Kaiju model. It surpassed the 255 node limit. So Clever me tried to split the models instead into multiple parts and use attachments and a single anim file to bypass this. however I think I ran into a problem.

So now when I try to make it the arms aren't complete and the arms are less than 255 node limit so I pondered if the attachment node for models have an even lesser limit? Is there still hope to bypass the 255 node limit by other clever ways?
