Strange color puzzle machine. Textures in PBR 2048, separate models in FBX and Blend format. Can you make up riddles?

I used these models to invent a riddle, You can invent it too.

“Machine that shoots a laser through crystals. Using the color of the 5 lenses, you choose the color of the layzer and the direction in which the layzer goes. I had to draw a star for something to happen.”
