Security Hologram Sticker I'd like to know how to create a holographic material using nodes/texture maps to replicate a security hologram like this:


I cannot seem to find any information regarding this anywhere. I have tried myself numerous times to replicate this effect using gradient/metallic nodes and texture maps to make the reflection look convincing but I cannot seem to get a good result. Any advice would be greatly appreciated!
Thank you.
If you want to make a shiny, iridescent material, it is very simple.  All you need to do is follow my node setup, which I have provided below:
once that is done, you should have a very iridescent material (see image below).

If you want  to make a security hologram-like sticker in your question, you can simply texture paint an image of a sticker onto a mesh, then add a mix shader and mix your iridescent shader with the image texture (see image below)

hope this helped!  If you encounter further problems, let me know and I'll be happy to help. : )
(PS, you might need to enlarge the images to see the node setup.   sorry about how small they are)
