BlinkScript
BlinkScript: runs a Blink kernel (Nuke BlinkScript) on the GPU.
BlinkScript: runs a Blink kernel (Nuke BlinkScript) on the GPU. Edit the kernel source, press Recompile (Ctrl+Enter); params become knobs, images become inputs. Scatter writes, reduction / rolling / particle kernels are not supported (docs/notes/blinkscript.md). Specify Output Format sets the output size; otherwise it follows the first input.

Nuke equivalent
Imports from and exports to Nuke's BlinkScript.
Nuke knobs not in this list import as a knob of the same name, or are kept unchanged for export. See .nk import.

- BlinkScript kernel (
examples/blink/blinkscript_saturation.oink): The default BlinkScript kernel (a saturation kernel written in Nuke's Blink language) running on the GPU through Oink's Blink-to-GLSL translator. Edit the kernel source in the properties and recompile.
