Hi, I'm new to this forum and I'm looking forward to getting better at using Blender. I've been modeling the Airbus A320 and I just got the windscreen modeled. In the viewport, it looks fine, but with rendering, there is some strange artifacting with the lighting. Adding to this, I have an issue with the curves in the windscreen at the edges which cause Ngons which I've learned cannot be used in games which I intend to use this model for, any tips on what to do for these would be appreciated.
Thank you in advance for the help!
Here is what my render looks like. I just joined the community so I couldn’t upload both into the same post

yepp… you might think about adding some support loops and also not having concave polygonson the outer edges:
Also maybe your polygons have opposing normals (check with Viewport overlays → Face Orientaion) ?? And all are smoothed shaded ??
