Smart HDRI Sync – Addon that fully automates

the interaction between HDRI and light sources.  

No more struggling with manual adjustments—achieve 

perfect lighting 

in seconds!

Clean UI experience.

Say goodbye to complicated node-based HDRI setups. With Smart HDRI Sync’s interactive buttons you can adjust HDRI positioning, rotation and lighting directly in the viewport making HDRI lighting adjustments, faster and more intuitive than ever.

HDRI Snapping to Light Source

Easily snap your HDRI with scene’s lighting. Let your environment automatically follows the selected light source ensuring perfect shading, and illumination consistency. No more guesswork—just focus on creativity.

Rotate Light to HDRI

Achieve accurate HDRI lighting in Blender by automatically detecting the main light source in your HDRI and aligning the scene’s lamp to ensure perfectly matched illumination and shadow casting This eliminates common HDRI lighting inconsistencies making your scene look more natural.

Rotate HDRI to Light 

If your scene lighting is set up but the environment doesn’t. Smart HDRI Sync allows you to rotate the HDRI to match the scene’s lights with a single click. No more manual HDRI rotations or imprecise adjustments—your environment will seamlessly fit your existing lighting setup.

Automatic Light Color Matching 

To maintain a consistent and realistic lighting balance the addon automatically adapts the lamp’s color based on the HDRI’s dominant light source. This ensures your artificial light blends seamlessly with the environment 

Drag to Rotate Along Light Source Normal 

Adjust your HDRI in real time along the light's normal vector bypassing the tedious awkward mapping node rotations. This tool offers intuitive control making it effortless to dial in the perfect lighting angle for your composition.

Above Horizon Filter 

This function automatically excludes everything below the horizon line from HDRI analysis By focusing solely on the sky relevant part of the environment-it ensures that the lamp’s orientation and color synchronization are based on the most accurate lighting data. This is especially useful for HDRI setups where ground elements might reflect or create unwanted lighting effects.

Instant HDRI Rotation Reset 

Quickly undo all rotations, alignments and snapping adjustments applied through the addon This ensures a clean slate allowing you to experiment freely without manually resetting each setting Perfect for refining your lighting workflow with precision and flexibility.
