Flat shaded mesh, strange triangle colors

Questions & Answers
1

Hi guys.
I wrote a script, which manually generates a mesh using perlin noise, and then I use flat shading technique, where I make all vertices unique. I triple checked how I create uvs, triangles and vertices and assign white color to all of them.
After mesh is created, I call mesh.RecalculateNormals();

The problem can be observed on the video below.
Rotating the directional light causes smooth color change, that’s OK, that’s what I would expect, but when rotation reaches some value, some of the triangles go immediately to black without any colortransition.
What can be the problem? Or is that normal?

Fixed as set the Material’s shader to Legacy/Diffuce Fast from Vertex Color

Hey Could you please send me your code i’ve been trying to make a script that would generate a map using perlin noise but it keeps being smooth instead of being lowpoly like yours :frowning: can you please send me your scripts or full project i would really appreciate that :wink:
