### Integer Setting
|
||||
### Integer Settings
|
||||
This node is designed to give output as a raw value of 1 or 2 integers. Enable = 2, Disable = 1.
|
||||
|
||||
Use case: This can be set up before a two-way switch, allowing workflow logical control to flow in one or the other direction. As of now, it only controls two logical flows. In the future, we will upgrade the node to support three or more logical switch flows.
|
||||
|
||||
|
||||
|
||||
### Integer Settings Advanced
|
||||
This node is designed to give output as a raw value of 1, 2 or 3 integers. Only one integer output can be enabled at a time. Connect this node with the new Switch (Three Way) for logical control.
|
||||
|
||||
|
||||
|
||||
### Switch (Two Way) / Switch (Three Way)
|
||||
Unlike traditional switches, which accept only one type of input, these switches will accept multiple input types and pass through those inputs if connected to the correct output. Now seamlessly connect Switch (Two Way) with the Integer Settings and the Switch (Three Way) with the Integer Settings Advanced Nodes.
|
||||
|
||||
|
||||
|
||||
### Choose Upscale Model
|
||||
A simple node that can be connected with a boolean logic. A true response will use upscale model 1, and a false response will use upscale model 2.
|
||||
|
||||
|
||||
|
||||
|
||||
### Perturbation Texture Node
|
||||
This node adds realistic texture overlays to images using advanced noise generation techniques. This node is particularly useful for enhancing portraits, adding film grain effects, or creating natural surface textures. This is an advanced version of the Noise Plus Blend Node. The node generates multi-channel noise patterns that respect the original image's color distribution, creating realistic textures that enhance rather than overpower the source material. Can be used pre/post upscale (pixel-to-pixel).
|
||||
|
||||
**Settings:**<br>
|
||||
noise_scale: 0.25 - 0.50.<br>
|
||||
texture_strength: 10-50.<br>
|
||||
perturbation_factor: 0.10-0.25.
|
||||
|
||||
Node can be used with or without a mask.
|
||||
|
||||
|
||||
|
||||
|
||||
**Texture Type:**<br>
|
||||
Natural: Balanced, organic texture — ideal for stylized portraits or general image enhancement without overwhelming details.<br>
|
||||
Film Grain: Adds cinematic noise — great for final renders or creative film looks.<br>
|
||||
Skin Pore: Subtle realism — best for **close-ups** or portraits needing natural facial texture.<br>
|
||||
Fine Details: Emphasizes high-frequency textures — perfect for mechanical, fabric, or intricate object renders.

||||

HiDream supports hard-coded resolutions, similar to SDXL, and is very different from the pixel-based resolution supported by Flux.

### Text Bridge
|
||||
Utility node that provides flexible text input/output management with manual editing capabilities. This node serves as a text processing hub, accepting text from other nodes while allowing for manual overrides and edits.
|
||||
|
||||
**Passthrough Mode:** When connected to another node and the text input field is empty, the incoming text is passed through unchanged.<br>
|
||||
**Manual Override:** When text is entered in the text input field, it uses that text instead of any passthrough input.<br>
|
||||
**Standalone Mode:** Functions as a simple text input node when no passthrough connection is made.
