Method #

This node generates an image of a QR code from a given string. A QR code is simply an encoded string of text, and so are ideal as a quick link to a URL. The generated QR code is adaptive, and so will expand and contract based on the length of text added as it needs to.

Although most QR codes are predominately black and white, they do not have to be. A QR code can be any colour and can even include more than 2 different colours. The key takeaway is that the QR scanner is able to distinguish between foreground and background modules (the squares) in order to detect the pattern and decode the string contained within it.

This node can be connected to any node which accepts an image input.

Parameters

These properties control the 3D transforms of the node. Transforms will generally be inherited by child nodes, although they can be ignored through the Inherit Transform Channels attributes.

ParameterDetails
Position XMove along the local x-axis.
Position YMove along the local y-axis.
Position ZMove along the local z-axis.
Rotation HeadingRotate around the local y-axis.
Rotation PitchRotate around the local x-axis.
Rotation BankRotate around the local z-axis.
Scale XScale along the local x-axis.
Scale YScale along the local y-axis.
Scale ZScale along the local z-axis.

Toggle which transform channels should be inherited from the parent node. By default, all transforms will be inherited.

ParameterDetails
Position XToggle inheritance of the X Position from the parent.
Position YToggle inheritance of the Y Position from the parent.
Position ZToggle inheritance of the Z Position from the parent.
Rotation HeadingToggle inheritance of the Rotation Heading from the parent.
Rotation PitchToggle inheritance of the Rotation Pitch from the parent.
Rotation BankToggle inheritance of the Rotation Bank from the parent.
Scale XToggle inheritance of the X Scale from the parent.
Scale YToggle inheritance of the Y Scale from the parent.
Scale ZToggle inheritance of the Z Scale from the parent.
World Position OnlyInherit the world position from the parent only, rotation and scale will be ignored. Overrides above properties.
Inherit TimeToggle inheritance of time from the parent.

These properties control the core behaviours of the node.

ParameterDetails
ActiveEnables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Preview In ViewportPreview the effect blended with alpha in the viewport.
Preview RGB In ViewportPreview the colour values in the viewport.
Preview Alpha In ViewportPreview the alpha values in the viewport.
WidthThe resolution of the effect along its width.
HeightThe resolution of the effect along its height.
Update Time ModeHow the generator updates with relation to the timecode.
  • Locked To Timecode : The generator animations are locked to the timecode and the same time will always yield the same result.
  • Running / Loopable : The generator animations are disconnected from the timecode and will loop seamlessly at the end of the layer.
Static Image (Process Only Once)Only process the image once, making a more efficient scene. Animated Post-FX nodes will not function with this enabled.
Text StringThe string of text to encode in the QR code.
Error Correction LevelThe error correction level. A higher ECC level will yield a barcode that tolerates more damaged parts while preserving the payload data.
  • Low : A low error correction level. The QR Code can tolerate about 7% erroneous codewords.
  • Medium : A medium error correction level. The QR Code can tolerate about 15% erroneous codewords.
  • Quartile : A quartile correction level. The QR Code can tolerate about 25% erroneous codewords.
  • High : A high error correction level. The QR Code can tolerate about 30% erroneous codewords.
Version Range MinThe minimum version range. Different versions have a different amount of modules. Eg. Version 1 has 21x21 modules and version 40 has 177x177 modules.
Version Range MaxThe maximum version range. Different versions have a different amount of modules. Eg. Version 1 has 21x21 modules and version 40 has 177x177 modules.
Border (in Modules)The size of the border around the modules within the QR code.

These properties control how the generators are coloured and blended with other images.

ParameterDetails
ColourChange the colour of the generated image.
Blend AmountThe amount the generator is blended with the output.
Blend ModeChoose how the image blends with the scene. See Blend Modes for details.
  • Solid : The generator is solid, with a filled alpha channel.
  • Blend : The generator RGBA values have matching alpha channels.
  • Pre-Mul Blend : The RGB values are solid white, and the generator colours are stored in the alpha channel alpha. Usually gives the best results for colour blending.
