I just finished rigging my character from scratch in blender 2.8.75 and imported it into Unity and I get the following message:

Can't calculate tangents because mesh "..." doesn't contain normals.

This error is relating to all 76 of my touch bones in my blender character. I applied the location, rotation, and scale in blender, but I don't know why I'm getting this particular error when I import it into Unity. I'm a newbie at all this. After I finished with the bones on my Blender character and imported it into Unity, everything worked up until that point. But now that the rigging is all finished, I get this error.

Does anyone have any ideas, or would I be better off submitting this to the Unity forum? Not sure since it related to both Blender and Unity. Thanks in advance.
