Renderer Settings
The Renderer Settings dialog sets the render frame rate and the gradient color space. A lower frame rate trades smoothness for lower GPU and network load.
Open the dialog from Edit > Renderer Settings. It has two controls: the render frame rate and the gradient color space.
FPS
Spectralite renders at the FPS set here, from 1 to 60. The default is 60 FPS, which most fixtures accept without banding. A lower value reduces GPU and network load, but fast-moving effects look less smooth.
Two reasons to lower it:
- The machine runs hot enough that its fans are audible during a show.
- You send large pixel counts over Art-Net, and the network is the bottleneck. If 60 FPS drops packets, see Hardware Troubleshooting for buffer-size tuning.
Changes apply immediately and save with the project.
Gradient color space
This setting picks the color space in which Spectralite blends between two gradient stops. The choice affects every gradient swatch and the light sent to fixtures.
- Oklch (default): perceptually even. The hue travels around the wheel, so a red-to-blue fade stays saturated through purple.
- Oklab: perceptually even. It blends straight across the wheel, so the same fade passes through a muted middle.
- Okhsv: perceptually even. It holds the strongest channel through a hue rotation.
- Linear sRGB: blends the light itself, which is what two real lights crossfading do. A red-to-blue fade dims through gray in the middle.
- Gamma-corrected linear RGB: the same light blend, re-encoded to sRGB.
- HSL and HSV: classic hue-angle blends.
For xyY and Temp gradients, Okhsv, HSL, and HSV blend the same way as Oklch. They differ only on Channels gradients. A Temp gradient between two whites sweeps in even steps of warmth, whatever the space. When you switch spaces, every gradient re-renders at once, and you can undo the change.
