INDG_CustomNodes

Custom ComfyUI nodes for the INDG Toolset.

Node reference

| Node | Class name | Category | Short description | |------|-----------|----------|-------------------| | INDG Flexible Image Batch | INDGFlexibleImageBatch | INDG/image | Batch 1–7 images into one tensor; optional slots silently skipped | | INDG Output Path | INDGOutputPath | INDG/utils | Combine base path / client / product / filename into one path string | | NBP RAM Cleanup | NBPRAMCleanup | INDG/utils | Aggressively free CPU RAM at the end of a workflow |

Nodes

INDG Flexible Image Batch (INDGFlexibleImageBatch)

Category: INDG/image

Accepts 1–7 images and concatenates them into a single batched IMAGE tensor. Unconnected optional slots are silently skipped — no dummy wiring needed. Images with mismatched dimensions are automatically resized to match image_1.

Designed to replace the dynamic BatchImagesNode pattern so that the RP Interface workflow builder can treat every input as a plain node_id → input_key → value patch, with no special backend logic required.

Inputs

  • image_1 (required)
  • image_2 … image_7 (optional)

Output

  • images — batched IMAGE tensor

INDG Output Path (INDGOutputPath)

Category: INDG/utils

Combines four path segments into a single output string — replacing the current pattern of multiple PrimitiveStringMultiline + concat nodes.

Connect the output directly to a MetaSaver filename_prefix input (or any node that expects a path string). Empty segments are silently skipped so you can leave optional parts blank without getting double slashes.

Inputs

  • client (required) — client name, e.g. "Deployed/HD"
  • product (required) — project/product name, e.g. "ProjectName"
  • filename (required) — filename prefix, e.g. "Shot001"
  • base_path (optional, default "ComfyUI") — root folder; leave blank to omit

Output

  • path — joined path string, e.g. "ComfyUI/Deployed/HD/ProjectName/Shot001"

NBP RAM Cleanup (NBPRAMCleanup)

Category: INDG/utils

Chain at the end of any workflow to aggressively free CPU RAM. Clears PromptExecutor node-output caches, unloads models from VRAM, runs Python GC, and returns freed pages to the OS via tcmalloc or libc.

Optional passthrough_image input lets you connect it inline without breaking the graph.

Installation

Clone into your ComfyUI custom_nodes directory:

cd /ComfyUI/custom_nodes
git clone https://github.com/SorenWeile/INDG_CustomNodes.git

No extra dependencies required beyond what ComfyUI already provides. psutil is optional — install it for RAM usage stats in the NBP RAM Cleanup node.
