Rotation Error

So I imported a model from blender, and as blenderer’s know up is on the z axis. However unity has y as up axis. So now I have a model where up is z and forward is y. So is there any way to fix this issue? Or is it possible to change it in blender so that up is y?

What are you exporting the model as? Are you importing the .blend, a .fbx, etc? The .fbx exporter lets you change the axes on export.

You could also just rotate it in unity, and either parent it to an empty or vice versa to suit your needs.

If all else fails, just rotate it in blender, save, and re-import it.
