Define a visual goal, break the scene into background, midground, and foreground layers, then list every shader in the stack. Plan a camera choreography and a second-by-second animation timeline before writing any code.

Group shaders by role: surface materials, environmental effects like fog and sky, VFX such as particles and portals, and post-processing passes like bloom and color grading. Compose them per scene layer so each system has a clear responsibility.

GSAP timelines, Theatre.js, Motion One, and the built-in Three.js AnimationMixer all drive camera and object animation. Spline paths and scroll-driven rigs are common patterns for fly-throughs and orbit shots.

Yes, but shader complexity must be budgeted. Estimate GPU cost as low, medium, high, or extreme, then provide a reduced mobile-safe version alongside desktop and premium variants with fewer particles and simpler post-processing.

Apply bloom, depth of field, motion blur, chromatic aberration, or film grain after the core scene renders to add cinematic polish. Each pass adds GPU cost, so include them in the performance budget and disable heavy passes on mobile.
