What is K-Cycles Flares and Post FX?
- K-Cycles Flares is the only Cycles lens flare implementation in the viewport.
- Lens flare types include glare, anamorphic and ghosts effects.
- Flares are physically based on light brightness, size and color.
- K-Cycles Flares have many artistic controls to create all types of amazing flare effects.
- Animation ready with all the settings fully keyable and with previews on the viewport.
- Works with Cycles "Sky Texture” like Nishita and others, commercial sky addons, HDRI’s, or real and emission lights.
- EASY to use and design to give great results without the need of Photoshop or compositor.
Plus the 2x or more performance improvements for Cycles. K-Cycles with Cycles-X is in development and will be a free upgrade.
