Realistic Particle Mobile Background Animation

I need a subtle yet engaging particle background for my mobile app. The animation must look realistic—think gentle dust motes or soft light particles floating in space—and run smoothly on both iOS and Android without draining battery or memory. A seamless loop is essential so the user never notices a jump.

I’m flexible on the production workflow: After Effects, Blender, or even a real-time solution such as Lottie JSON is fine, as long as the final asset arrives lightweight and ready to drop behind the UI. I’ll share brand colors once we start so you can tint the particles to match the app’s palette.

Deliverables
• 10–15 s seamless loop in a mobile-friendly format (.mov with alpha, .mp4, or Lottie)
• Source project file for future color tweaks
• Quick preview (GIF or MP4) for sign-off before final export

If you’ve created realistic particle backgrounds before, a brief show-and-tell link will help me choose quickly.
