please forgive me as i am not the person doing the art. so my question might be phased a little wrong. however the artist i am working with is creating a model. the model has 9 sub objects in it. however it has close to 30 bones. what i am noticing is that all the bones are creating a game object when i import the model. so there are on the order of 40 game objects in this one model. is this normal for blender exporting? any tips i can give to my artist to reduce the count? does the count effect my performance at all?
you need to merge all the objects together in blender, so that they are one:
Select all the objects that make up the model, and press Ctrl+J (blender will join them all into the last selected object/active object)
They will then be separate meshes within a single object, which Unity will read as one draw count.
this shouldn’t affect any of the bone weighting.
As for the count affecting the performance…I can’t really say, but I believe I did read a while back that there is a limit to how many objects can be driven by bones on mobile…
but on PC builds I don’t think you will notice a difference in performance.
