It would be nice to have a config option to change rendering from 2D planes to 1 unit thick cubes. This would look like items you hold in your hand and people who liked the look of the old tails mod or who want to look at their character from the side would like this switch probably, as it is up to the player to decide how they want the skins to render. This would also fit well with the Skin Layers mod, which updates the 2nd layer to render in 3d.

There would be a intensive amount of work to accomplish this probably, but it would also be liked by many probably.

Extrusion has been planned for a while, but requires a fairly significant overhaul to the render system.

Maybe, if it's easier, you could just make it work with 3D Skin Layers.

That's not how graphics programming works. Even if it was, I don't want a dependency on a mod only available for a few of Ears' supported platforms.

agree + there are some things equally or even more important rn. Like for example maybe a website to graphically design body parts added by ears without requiring a external program.
