I'm new to 3D, when I try to render my first model it shows some grey polygons throughout the body of the character. Face Orientation is all correct. I'm using Cycles... Eevee makes the render a little better, but still shows some polys greyed-out.
For context: Before I started making this project(it has only 508 Tris), I changed the render settings according to Ponte Ryuurui's Hard Surface tutorial. Also this was my first time actually pressing the button to render something.
