This material study was inspired by the Bifrost ("Bifröst") bridge seen in Marvel's Thor Ragnarok and was requested by a YouTube subscriber.
It is all based on noise textures (=100% procedural) and by adding several layers of detail and animating the texture coordinates we can quickly create a cool looking rainbow bridge!
You can get the .blend file of the final animation for Blender 2.81 over at my Patreon.
