The Final Result

Of the 47 people who submitted for this one, I alone apparently went straight for the worst case scenario: what DOES a hotel toilet reveal under blacklight.

No regrets.

It was also a good excuse to play with image textures and shaders.

🎓Lessons Learned🎓

UV light combo

UV Light Approximation

Glow Colour

Transparency masks

The shader is really simple. Where the ink splatter is white, we use the original material. Where the ink splatter is black, we use our radioactive-looking emissive material. On some pngs, I used the alpha channel rather than black and white (color channel).

From there, it was just about adjusting the uv’s.
