I am wondering if there is a difference in performance. I am working on a WebGL project. I have a room with chairs. Should I model 1 chair export is as an .fbx and duplicate it in Unity or duplicate it in Blender and export 1 fbx with all the objects.
Is there a performance difference?
the difference would be so little, that if working with only 1 fbx is harder I would export them as independant fbx. But yes, having multiple gameobjects for the stairs means that they will have, for example, multiple transforms, that would use extra memory. Also take into account that if they are a single gameobject, you wont be able to start loading components of the scene at runtime (you would need to load all the stairs at once)
