This project shows how to implement Ratchet & Clank™ pixelizer weapon fx in Unity3D.
Please watch the following video to have a better understanding of how it works : https://youtu.be/b16JFKrGrFE
Ratchet & Clank is a trademark of SONY INTERACTIVE ENTERTAINMENT LLC in the U.S. and/or other countries.
This effect is implemented using a secondary camera to render the character to a tiny texture (TextureSize parameter on the PixelizerRenderer component).
The PixelizerRenderer renders the voxels of the texture every frame using the Pixelated material & shader.
The Pixelizer prefab contains all the needed elements to pixelate a 3d object. You just have to set the parameter Target on the PixelizerRenderer and adjust the TextureSize and VoxelSize so it can contain the character/object.
