How to achieve a specular speckle effect (see video below)? This effect is visible in various places such as car paints, plastic coatings on mobile phones, christmas ornaments, snow etc.

It can quite easily be achieved using the alShaders by Anders Langlands. In particular the alFlake shader is required. You need to connect it to the alSurface shader’s Specular Normal attribute.

You can download the shader here – Maya, C4D.
