Renderer Settings
FPS, render controls, and gradient color space
Renderer Settings
Open from Edit > Renderer Settings. The dialog exposes two controls: render frame rate and gradient color space.
FPS
Rendering targets the FPS set here. Valid values range from 1 to 60. The default is 60 FPS, which most fixtures accept without banding. Lower values reduce GPU and network load at the cost of visible smoothness on fast-moving effects.
Two reasons to lower it:
- Running on a thermally constrained machine where the fans are audible during a show.
- Sending large pixel counts over Art-Net where the network is the bottleneck. See Hardware Troubleshooting for buffer-size tuning if 60 FPS is dropping packets.
Changes apply immediately and save with the project.
Gradient color space
Selects the color space used when interpolating between gradient stops. The choice affects every gradient swatch and the rendered output sent to fixtures. Available options:
- Oklab (default): perceptually uniform; smooth lightness transitions.
- Oklch: perceptually uniform with hue-angle interpolation.
- Okhsv: perceptually uniform; preserves peak channel through hue rotations.
- Linear sRGB: per-channel; matches pre-2026 behavior.
- Gamma-corrected linear RGB: per-channel in linear-light, re-encoded to sRGB.
- HSL: classic HSL; hue-angle interpolation.
- HSV: classic HSV; hue-angle interpolation.
Switching spaces recomputes every gradient lookup table. The change is undoable.
