Beautiful 8-bit Pixel Art Scenes Animated Through Color Cycling

Yes this is possible on 2D or 3D stuff in UE4. There are two different approaches, depending on what you’re trying to accomplish.

If you want to do something like team colors or possibly mega man / shovel knight sorts of things, you can use a mask texture to indicate where to colorize and use a vector parameter instead of the source texture in the areas the mask indicates. You can then animate that color and do whatever you want.

If you want to do straight up palletized textures, then use the source texture as an index into a palette texture (you’ll need to make the source texture uncompressed for this to have any realistic chance of looking good). You would do this by making the UV for the palette texture from say the G channel of the index texture. In order to do animations, you’d either make the palette texture dynamic and modify it each frame, or you can smear the texture across the other axis, turning it into a 2D texture where U is color and V is time. Keep the colors that don’t animate constant in a column, and rotate the colors that you do want to animate.

Awesome, thanks. Didn’t you do something similar in the second 2D side-scroller video with the projectile?
