Hello, I created a Hexagon Map, but it has really weird Shaddows.

I Created it with the Procedural Mesh Compoment, with Vertecies and Triangles (I left UV, Normals and Tangents empty, cause i first wanted to get my Mesh working. Also i don’t really know how i’d compute them / if they are even neccesary).

I’ll link some Images where you can see what i mean.

I wonder what i’m missing/doing wrong so if anyone could give me a helping hand about what i could change in the Settings / Code to make it look good/work I’d be greatfull.

Have a nice Day!
