I have a model of a light pole (2 materials, 9 meshes).
Some time ago, I made it into a prefab and attached some physics and scripts to it. Today I noticed that my draw calls for these electric poles weren't being batched.
First, I removed all the components from the prefab -- still not batching.
Next, I put just the model into the scene (without a prefab) -- it was batching. This is the same exact model referenced from my prefab, yet now it's batching.
These poles aren't referenced in any scripts. There are no lights in the scene.
So finally, I created an empty scene with my prefab light poles. This time, everything was batching properly, including my prefab. Does anyone know why this is happening?
