3D Pixel Art Shader
A three part shader package for making pixel art games in Unreal Engine. There is a cel shaded material you can use in conjunction with this, or else where, as well as the outline shader. Add the other material instance to blendables first before adding the pixel art material instance, that way the pixel shader will pixelate and posterize the outlines as well.
To add to your project, make sure your project is not open. Click and drag the files into your content folder. When you open your project again, they will be there.
