I’ll tell you—first I map the source, then I find the exact angle where the light catches the glass just enough to split, and then I layer a thin film over it so it doesn’t bleed into the rest of the room. A little trick: a small, warm diffuser in the corner pulls the glare out of the viewer’s eye, making the flare feel intentional instead of accidental. That’s the secret.

Got it, I’ll keep the film tight and the glow consistent. If it drifts, I’ll tweak the angle until it stays in rhythm.
