Summary[edit]
The Switch POP lets you choose one of the inputs, and outputs the input unchanged. The number of points, vertices and primitives of all of the inputs can be different.
It uses a numeric parameter, Index, to choose the input, with 0 referring to the first input. If Index is fractional - a non-integer, it can blend two inputs: If the inputs have the same number of points, vertices and primitives, they can be blended, two adjacent inputs at a time.
Tip: Since it blends only adjacent inputs (input N with input N+1 or N-1), to blend from the last input to the first input, attach the first input again as the last input, and use CHOPs to loop from 0 to number-of-inputs snap back to 0 when Index reaches number-of-inputs.
If Index is out of range, it clamps.
See the Blend POP to blend arbitrary combinations of inputs.
The Switch POP's architecture for handling multiple inputs is similar to the Attribute Combine POP.

Parameter Color Space
parmcolorspace - ⊞ - Controls how all color parameters on this node are interpreted. The color values as treated as being in the selected color space, and are converted to the Working Color Space before they are used as part of the node's operation. Note that this does not change the color space of the node itself, as that is always in the Working Color Space.
- sRGB
srgb- sRGB color space, with sRGB transfer function. Considered an SDR color space with respect to Reference White.
- sRGB - Linear
srgblinear- sRGB color space, with linear transfer function. Considered an SDR color space with respect to Reference White.
- Rec.601 (NTSC)
rec601ntsc- Rec.601 with NTSC primaries color space, with Rec.601 transfer function. Considered an SDR color space with respect to Reference White.
- Rec.709
rec709- Rec.709 color space, with Rec.709 (same as Rec.2020) transfer function. Considered an SDR color space with respect to Reference White.
- Rec.2020
rec2020- Rec.2020 color space, with Rec.2020 (same as Rec.709) transfer function. Considered an HDR color space with respect to Reference White.
- DCI-P3
dcip3- DCI-P3 color space, with D65 white point and 2.6 gamma transfer function. Considered an HDR color space with respect to Reference White.
- DCI-P3 (D60)
dcip3d60- DCI-P3 "D60 sim" color space, with D60 white point, and 2.6 gamma transfer function. Considered an HDR color space with respect to Reference White.
- Display-P3 (D65)
displayp3d65- Display-P3 color space, with D65 white point, and sRGB gamma transfer function. Considered an HDR color space with respect to Reference White.
- ACES2065-1
aces2065-1- ACES 2065-1 (also known as ACES AP0) color space, with a linear gamma transfer function. Considered an HDR color space with respect to Reference White.
- ACEScg
acescg- ACEScg (also known as ACES AP1) color space, with a linear gamma transfer function. Considered an HDR color space with respect to Reference White.
- Passthrough
passthrough- When selected, the color values will be used as-is in the operation, without any modification or attempt to convert them into the Working Color Space.
Parameter Reference White
parmreferencewhite - ⊞ - When converting a parameter color value to the Working Color Space, this controls how it should be treated with respect to Reference White. If the Working Color Space is the same Reference White, then no adjustment is done. If they are different, then the Reference White level (brightness) of this color will be adjusted to the range expected by the Working Color Space. For example if the project is set to have a SDR Reference White of 120 nits, and the HDR Reference White is 80 nits, then a color of (1, 1, 1), which is 120 nits in the SDR color space, will be converted to be (1.5, 1.5, 1.5), which is 120 nits still in the HDR Working Color Space.
- Default For Color Space
default- Will use either the SDR or the HDR Reference White, based on the color space selected.
- Standard (SDR)
sdr- Will treat the Parameter Color Space as SDR for it's reference white value.
- High (HDR)
hdr- Will treat the Parameter Color Space as HDR for it's reference white value.
