Recommended resolution is 1080p

This is not real-time, It can quickly get very slow at higher resolutions.

Supported versions: 4.2

This may work on previous blender versions with CPU rendering but it is EXTREMELY slow, at 1080p you are waiting 5+ minutes per frame to run the node setup and there are many bugs.

Node execution time (RTX 4070ti): ~8 seconds @1080p

IMPORTANT:

For lens flares to be generated correctly in CYCLES or EEVEE, you need to turn off light clamping by setting it to 0 or by using a high number like 500.

Otherwise, flares will be dim or unnoticeable when the light source is shown through reflections and translucent materials.

Known Issues:

• When the light source becomes extremely small, some flickering can occur.

• These flares are screenspace, they will fade out when out of frame.
