Utils

Small helpers that keep a workflow tidy: a node with five sliders, an on/off switch that can drive many places at once, and a pair of nodes that carries up to ten wires as one. Find them under NH-Nodes → Utils in the node menu; Pack Universal (NH) and Unpack Universal (NH) are under NH-Nodes → Utils → Pipe.

On this page

Node	Use it to
Multi-Slider (FLOAT)	Set up to five decimal numbers from one node
Multi-Slider (INT)	Set up to five whole numbers from one node
Boolean Switch (NH)	Flip one on/off switch that can drive many places
Pack Universal (NH)	Bundle up to ten values into one wire
Unpack Universal (NH)	Take one value out of that wire
Universal Slider Builder (NH)	Deprecated: use the Multi-Sliders instead

In the tables, * means any data type.

Multi-Slider (FLOAT)

Five float sliders in one node, each with its own output.

Use it when you tune several numbers, such as LoRA strengths or a denoise value, and want them on one compact panel instead of five separate nodes.

Input	Type	Default	Description
float_1 … float_5	FLOAT	0.0	Five sliders, each from -1.0 to 1.0 in steps of 0.01.

Output	Type	Description
Float 1 … Float 5	FLOAT	The value of the slider with the same number.

Example — one panel for a LoRA and the sampler

Multi-Slider (FLOAT) → Load LoRA Model Index (NH) / KSampler

Wire Float 1 into strength_model of the LoRA loader and Float 2 into denoise of KSampler. You now change both from one node.

Tip: The range is -1.0 to 1.0. For larger whole numbers use Multi-Slider (INT), or type the value into the target node.

---

Multi-Slider (INT)

Five integer sliders in one node, each with its own output.

Use it when you set several whole numbers, such as slot numbers or counts, from one panel.

Input	Type	Default	Description
int_1 … int_5	INT	0	Five sliders, each from -100 to 100 in steps of 1.

Output	Type	Description
Int 1 … Int 5	INT	The value of the slider with the same number.

Example — choose a LoRA and a VAE with two sliders

Multi-Slider (INT) → Load LoRA Model Index (NH) [index]
Multi-Slider (INT) → Load VAE Index (NH) [index]

Wire Int 1 into the index of the LoRA loader and Int 2 into the index of the VAE loader. Slots count from 1, and the sliders start at 0, so move them to 1 or higher before you run. A value below 1 selects nothing and blocks the loader (see Loaders).

---

Boolean Switch (NH)

One on/off switch that outputs a BOOLEAN.

Use it when one setting should control several places at once, for example the condition of If/Else (NH), the enabled input of Gate Switch (NH), or the reset of Counter (NH).

Input	Type	Default	Description
boolean_switch	BOOLEAN	true	The switch. It reads On (True) or Off (False).

Output	Type	Description
boolean	BOOLEAN	The state of the switch.

Example — fast or quality, from one switch

Boolean Switch (NH) → If/Else (NH)

Wire boolean into condition. Put the fast branch on if_true and the quality branch on if_false. Only the chosen branch runs. See Logic.

---

Pack Universal (NH)

Bundles up to ten values of any type into one wire, an NH_UNIVERSAL_PIPE.

Use it when many wires (model, CLIP, VAE, prompts, numbers) travel to the same distant part of a workflow and one wire would keep the canvas tidy.

Input	Type	Default	Description
input_0 … input_9	*	not connected	Optional. A value to store. Each one is stored at the position with the same number.

Output	Type	Description
package	NH_UNIVERSAL_PIPE	The pipe holding all the values.

How it works

• The pipe always has 10 positions, numbered 0 to 9. input_N goes to position N.
• A position you did not connect stays empty. It never shifts the others: if you connect only input_1 and input_3, they stay at positions 1 and 3.
• There are no type checks. Pack accepts any type, and Unpack Universal (NH) outputs any type.

---

Unpack Universal (NH)

Takes one value out of a pipe by its position number.

Use it when you have a pipe from Pack Universal (NH) and need one of its values.

Input	Type	Default	Description
index	INT	0	The position to read, 0 to 9. Use the number of the input_N you filled on Pack.
package	NH_UNIVERSAL_PIPE	—	Optional. The pipe to read.
pipe	NH_UNIVERSAL_PIPE	—	Optional. A second pipe input. It is used only when package is not connected.

Output	Type	Description
item	*	The value at that position.

How it works

• item is empty (None) when the position holds nothing, when index is outside 0 to 9, or when no pipe is connected. A node that needs a real value will usually stop with an error, so check the number first.
• One Unpack Universal (NH) returns one value. Add one per value you need.

Example — send a model set through one wire

Load Checkpoint → Pack Universal (NH) → Unpack Universal (NH) → KSampler

Plan the positions once, and use the same numbers on both sides:

On Pack	Carries	On Unpack (index)
input_0	MODEL	0
input_1	CLIP	1
input_2	VAE	2
input_3	positive prompt (STRING)	3

Tip: Give each Pack and Unpack pair a clear title, and keep the plan above in a note next to them.

---

Universal Slider Builder (NH)

Deprecated. This node is hidden from the node search and is kept only so that old workflows that contain it still load. It never produced outputs, so it cannot do anything useful. Replace it with Multi-Slider (FLOAT) or Multi-Slider (INT).

Input	Type	Default	Description
config	STRING	two example lines	A multiline text box. Each line was meant to define one slider (name, type, default, min, max, step), but the node never produced outputs, so the text has no effect on the workflow.
