tex/SubnetInput
Brings one of the enclosing texture subnet's inputs inside it.
Network
Inside a tex/Subnet, this shows the image wired into the subnet's input at the given index. Wire filters after it to work on an image the subnet is given from outside, rather than on a fixed source.
Inside a tex/Solver, input 0 is the picture as it is now: the solver's first input before the first step, then the result of the step before. Inputs 1 to 3 are the solver's other inputs, unchanged.
With nothing wired into the subnet's input, this node shows nothing, and a node reading it reports an error. Turn on fallback to make the input optional: it then shows a picture of one pixel of fallbackColor, for example white for a mask that hides nothing.
Parameters
| Name | Type | What it does |
|---|---|---|
| input | UInt8 | Which of the subnet's inputs this node stands for, counting from 0. |
| fallback | Bool | What this node shows when nothing is wired into the subnet's input. Off: nothing, and a node reading it reports an error. On: a picture of one pixel of fallbackColor. |
| fallbackColor | Color4 | The colour shown when fallback is on and nothing is wired into the subnet's input, read as it is (linear light), 8 bits per channel: pick the value that changes nothing, such as white for a mask or black for an amount to add. |
