I am creating a "Super Mario Invincibility Star" for my son. I've been working with resin now for roughly 5 years and have yet to see anyone create glowing resin with diffraction grating. I want to avoid more wasted time, money, product, patience, sanity, etc.
I have made holographic resin, and I have made glowing photo-luminescent resin. But I can't seem to pull off creating the two effects combined. My go-to resin so far has been Total Boat Tabletop 1/1 ratio. I have LIT extra fine glow powder pigment for the luminescence. And I did use diffraction grating sheets which I formed holographic silicone transfers, using Smooth-on Platinum 15 silicone mix.
Also, my man has 3D printed a model of the star with glow-in-the-dark filament, in hope that I could use it somehow in the creation of this star.
This is what I'm working with so far. But, I can't seem to put the puzzle together of what the best process would be. Any helpful suggestions would be appreciated.
