Enjoying UE's Texture Variation node to break up tiling UVs. Works well with a single texture read where the UV island edges aren't too visible but adding displacement causes ugly artifacts at those edges. Temporal dithering was worse so I extracted a blending weight to blend height or all textures.

Abandon pixels and retro like it's 1982.
Decided to tackle the Vectrex's graphical styling in #UE5. I did not want to use any post process edge filters or fake grid materials. Just straight up edges and vertex shader math.
