Yes, i know...
In above image, lower row, are tests for Corona AA filters. To show there's nothing similar going on here.
Please, don't answer with assumptions, speculations or ignorance.
In use is Corona Material shader with Diffuse (RGB 204, 80%) and procedural Cinema Tile Shader in Bumpmapping channel (sampling is always disabled for procedural textures!).
On Upper row you see 8bit png image texture for shaders in diffuse & mapping channels. And here again:
Scene:
Ground Plane=1sq.km.; (Number of UV tiles: A&B=50, C=30, D=20)
Corona Material Shader:
- Diffuse: RGB=204 / Brightness=80%
- Bumpmapping: Strength=1 / Texture=2k, Grayscale PNG 8bit
Cam.H=10m; Pitch= -30°
Poles H=10m (50x50cm), Distance between=10m
Below are different Sampling examples for Bitmap Shader.
