LumiFlow – Smart Lighting Add‑on for Blender

LumiFlow – Smart Lighting Add‑on for Blender (Pay What You Want)

LumiFlow is a smart lighting add‑on for Blender that helps you build professional product and cinematic lighting setups in minutes instead of hours. It combines intelligent light placement, ready‑made templates, and intuitive viewport controls so you can focus on art and storytelling, not wrestling with light objects.

You always get the full addon even if you pay $0. Paying more is simply a way to sponsor the project and keep LumiFlow improving for everyone.

If LumiFlow becomes part of your daily workflow and you can afford it, supporting the project here on Gumroad makes a huge difference.

What is LumiFlow?

LumiFlow is a free, open‑source lighting assistant for Blender 4.2+.

It gives you:

• Smart light placement directly under your cursor
• One‑click studio, commercial, and cinematic templates
• Interactive controls for distance, power, size, angle, temperature, and more
• Camera‑aware lighting that follows your active shot

Instead of manually adding and tweaking dozens of lights, LumiFlow helps you build clean, professional setups in just a few gestures.

Who is LumiFlow For?

• 3D artists who need fast, consistent lighting for products, stills, and animations
• Freelancers and studios who want repeatable, professional setups without building everything from scratch
• Blender users who find lighting confusing or time‑consuming and want smart defaults that “just work”

Whether you’re lighting jewelry, gadgets, cosmetics, or cinematic keyframes, LumiFlow is designed to get you to a solid starting point in seconds.
