I'm trying to render out some game models I'm working on and I'm running into issues with shadows. It seems my normals are affecting the shadows in the render.
Here's the character's head in the viewport -

Then the render turns out like this -

But then if I add a normal node and set the cusp angle to zero, I get this -

Is there a way to get shadows like that last image but with my existing normals?
Thanks,
Pete
