Node Library

MOD ships 130+ processing nodes (and growing) spanning image, texture, 3D/photogrammetry, video, audio, AI, and architecture/engineering/construction (AEC) workloads. Drag them onto the Workflow Builder canvas, or discover and run them over the API.

How a node works​

Every node is a containerized capability with:

  • Input / output / configuration schemas — what it consumes, produces, and the knobs it exposes (visible in the node's panel and via GET /node_definitions/{id}).
  • A credit cost (cost_in_credits) — typically 0–3 credits per run depending on the node.
  • Hardware variants (gpu_variants) — many nodes ship CUDA / ROCm / Intel / NPU / CPU builds, and MOD routes the run to matching hardware; CPU-only nodes run anywhere.
  • Batch mode — most processing nodes accept a folder and fan out across its files.

Inputs​

Every workflow starts with an input node that points at one of your files:

  • Image Input, Video Input, Audio Input, Mesh Input, Text Input
  • NeRF Input, Texture Set Input, Resource Input, Script Input

Image processing​

  • Resize Image — scale to target dimensions
  • Blur Detection — detect and score image blur
  • Blur Cleanup — AI-powered deblurring
  • Blur Image — CPU, GPU, and OpenCV variants
  • Background Extraction — remove backgrounds via ML segmentation
  • Transparent Background — alpha-matte cutout
  • Exposure Balance — normalize exposure across image sets
  • HDR Converter — tone-map / convert HDR imagery
  • Inpainting — fill masked regions (incl. depth-guided iterative inpaint)

Texture generation (PBR)​

Generate PBR material maps from photos — many have a fast classical path and an ML path:

  • Albedo (+ AlbedoML) — base color
  • Normal — normal maps
  • Roughness, Metalness, Specular
  • Ambient Occlusion (+ AmbientOcclusionML)
  • Cavity (+ CavityML) — fine surface detail
  • Height — height/displacement maps

3D & photogrammetry​

  • Colmap — structure-from-motion / dense reconstruction
  • DepthAnything — monocular depth estimation
  • Gaussian splatting — Instant Splat, Open Splat, SuperSplat, gaussian-pro
  • Radiance fields / NeRF — rad-foam, sparse-craft, and related splat/NeRF nodes
  • Mesh Converter — convert between OBJ, FBX, GLB, PLY, USD
  • Decimation — reduce polygon count while preserving shape
  • Place Mesh on Depth, SLDPRT / IFC / USD converters

Video​

  • Video Converter — transcode between MP4, MOV, AVI (FFmpeg CPU/GPU)
  • Video Split — split into frames or segments
  • Video Object Remover / Video Painter — inpaint moving objects

Audio & speech​

  • Audio Converter — MP3 / WAV / FLAC
  • ChatterboxTTS, OpenVoice — text-to-speech / voice

AI & ML​

  • Claude AI Process — LLM-assisted analysis
  • Chatbot — conversational node
  • CNN Image Classifier — image classification
  • SAM2 Mask — Segment Anything 2 masking
  • Anomalib — visual anomaly detection
  • Comic suite — description / LLM extract / pricing

AEC (architecture, engineering, construction)​

A domain pack for built-environment data:

  • IFC to GLB Converter — BIM model conversion
  • Excel Parser, Reference Table Loader, Multi-Source Reconciliation
  • Compliance Window Check, Labor Variance Check
  • Exception Report Generator, Provenance Stamp

Export & utilities​

  • Unity Export, Unreal Export, USD Converter, GLB Combine
  • Zip Download / Zip Folder — package outputs
  • Blender Script — run Blender Python
  • Script Input — run a custom script
  • Accelerator Benchmark — CPU/NPU/CUDA/ROCm/Intel compute benchmark
