The number of outputs of your shapediver model is defined as follows:
Number of ShapeDiverDisplayGeometry components X Size of the tree used in the Geometry parameter
Assuming you are using a low number of ShapeDiverDisplayGeometry components, the reason why you are exceeding the allowed limit is likely because you are inputting large trees, where each individual piece of geometry of your model is part of a different branch.
Unless you have a very specific reason to do so, then you can simply flatten your trees. Even better, if you are working with meshes (which is highly recommended), you can join them before outputting them, that way you will be down to a very low number of outputs.
Let me know if that helps. If the problem is different, I might need to have a look at your definition.
