Very cool! Looks like you made the right call with 16 ppm in that style. The pixel art foundation still comes through nice and clear. :)

32 pixels per meter. I tried to maintain that pretty consistently for this kit. With these metrics, I could get a 4m run in a 128x128 atlas, and 4 variations of that in a 256x256. That way you can mix things up enough in 4m increments that it doesn't get overly repetitious.

Every vertex is initialized to a default color, which is tunable. If there is no data saved for the vertex's position, it will use that instead. The default color is analogous to ambient environment color in normal lighting pipelines.

It's the latter. Whenever you apply vertex colors, the component iterates through each mesh vertex and looks up its color by position, then sets the array value at that index correspondingly. So the shader is agnostic to vertex positions - all it cares about is a single Vector4[].

My bad! I didn't realize I had my settings this way... If you try again it should work now. :p

Sure, feel free to send a DM!

The modular set used here is based on a study I did on the high-detail pixel art style used in Vagrant Story. If the atmosphere feels familiar, it is probably that. :)

You could think of it as using two Photoshop-like "layers" - a base color which you set across the scene, and a raw vertex color set by the paint tool. The final vertex color lerps between the two based on the alpha of the latter.

The vertex data is saved by (approximate) position relative to the mesh origin, rather than vert index, so it's resilient to re-exporting after changes. This was pretty important, since it would be unusable long-term if the vert color data broke whenever you re-exported.

I wanted to support a modular workflow, but this is difficult for vertex colors since those are normally set directly in the mesh. Instead, I wrote a component that sets a MaterialPropertyBlock on the mesh, which is populated with an array of vertex colors. The shader then references the array.

Thank you for the kind words! Unfortunately, the game is on pause right now, as I wasn't able to find other developers to help see it through. But I would love to return to it someday, and I'll continue to post more legacy screenshots from its development!

Thank you! That style is very near and dear to my heart, so they're a lot of fun to do.
