How to pixelate vertex color blend?

[Klausbdl]

I’m making a shader that allows to vertex paint another texture using vertex color and polybrush. I have this code that is pluged into the T argument of a Lerp between the two textures.

Over there in the Tiling and Offset node, there is a “pixelated uv” code that pixelates the Simple Noise.

When I paint in the red channel, the texture shows up as normal, but there is this weird line cutting the pixels at the border and I don’t know how to avoid it. Does anyone knows any solutions to this?

Not really possible to fix for the same reason as in the previous thread. You have to use a texture instead of vertex painting.

There’s no good way to pixelate per vertex interpolated values.

That’s unfortunate. Thank you.

The Quest for Efficient Per-Texel Lighting

Hello Unity community! I am writing a 3D, first person game that makes use of low res, low color, unfiltered textures and I looking for a way to light the game that doesn't spoil the charming retro look of the art. My plan was to light the scene conventionally, using unity lights and the unity standard shader, then create a posterization post-process effect. That was relatively easy. I created a function to map any RGB value to its nearest perceptual match in the game's palette and the results…
