What are the options, if I want to pixelate some 3d models on the screen? Not the full screen, nor the texture of the model. I want the image of the model to be like it is pixel art, but with ability to change perspective, lighting etc in runtime.
After investigating, found out that it is possible with using the camera duplicate, which renders only objects in specified layer with pixelization. Pixelization can be done via render effect, like in mentioned “Retro Pixel”. The pixelated image can be merged with main camera image via another render effect (compare depth buffer of two images to decide what image is in front at a given pixel)
