ComfyUI Depth Anything V3

Custom nodes for Depth Anything V3 integration with ComfyUI.

Simple workflow:

Advanced workflow:

Single image to 3d:

Multiple image to 3d:

Single image to mesh:

Use multi attention node for smooth video depth!

Demo Videos

You can use the multi-view node to use the cross attention feature of the main class of models. This is done to have a more consistent depth across frames of a video.

You can reconstruct 3D point clouds!

Even from multiple views, with the option to either match them (with icp) or leave them to use the predicted camera positions. You also have a field on the point cloud to show you which view each point came from.

Nodes

Model Loading

Download And Load Depth Anything V3 Model - Downloads and loads model from HuggingFace

• Inputs: model (variant), precision (auto/fp16/fp32/bf16)
• Output: da3_model
• Models auto-download to ComfyUI/models/depthanything3/

DA3 Enable Tiled Processing - Configure model for high-resolution images

• Inputs: da3_model, tile_size, overlap
• Output: da3_model (with tiled config)
• Use for 4K+ images to avoid OOM errors

Inference Nodes

Depth Anything V3 - Unified depth estimation with multiple normalization modes

• Inputs: da3_model, images, normalization_mode, camera_params (optional), resize_method, invert_depth, keep_model_size
• Outputs: depth, confidence, ray_origin, ray_direction, extrinsics, intrinsics, sky_mask
• Normalization Modes:
  • Standard: Original V3 min-max normalization (0-1 range, includes sky in normalization)
  • V2-Style (default): Disparity-based with content-aware contrast - best for ControlNet workflows
    • Sky appears BLACK (like Depth Anything V2)
    • Content-only normalization excludes sky from range calculation
    • Percentile-based contrast enhancement (1st-99th percentile)
    • Enhanced depth gradations via contrast boost
    • Subtle edge anti-aliasing for natural transitions
    • Contribution by Ltamann (TBG)
  • Raw: No normalization, outputs metric depth values for 3D reconstruction/point clouds

Note: The unified node always outputs all available data. Connect only the outputs you need - unused outputs are simply ignored.

Depth Anything V3 (Multi-View) - Process multiple images with cross-view attention

• Inputs: da3_model, images (batch), normalization_mode, resize_method, invert_depth
• Outputs: depth, confidence, ray_origin, ray_direction, extrinsics, intrinsics, sky_mask
• Normalization modes: Standard, V2-Style (default), Raw
• Use for video frames or multiple angles of same scene
• Normalizes depth across all views together for temporal/spatial consistency

3D Processing

DA3 to Point Cloud - Convert depth to point cloud using geometric unprojection

• Inputs: depth_raw, confidence, sky_mask (optional but recommended), intrinsics (optional), source_image (optional)
• Output: pointcloud
• Sky filtering: When sky_mask is connected, sky pixels are automatically excluded from the point cloud
• Input validation: Automatically detects and rejects normalized depth inputs (requires Raw mode)

DA3 to Point Cloud (Multi view) - Convert depth to point cloud using geometric unprojection

DA3 Save Point Cloud - Export to PLY format

DA3 to 3D Gaussians - Extract 3D Gaussian splats (placeholder)

DA3 Save 3D Gaussians - Export Gaussians to PLY

Camera Utilities

DA3 Create Camera Parameters - Create camera conditioning input

DA3 Parse Camera Pose - Parse camera parameters from JSON

Model Variants

Model	Size	Features
DA3-Small	80M	Fast, good quality
DA3-Base	220M	Balanced quality and speed
DA3-Large	350M	High quality, balanced
DA3-Giant	1.15B	Best quality, slower
DA3Mono-Large	350M	Optimized for monocular depth
DA3Metric-Large	350M	Metric depth estimation
DA3Nested-Giant-Large	1.4B	Combined model with metric scaling

Model Capabilities

Different models support different features:

Feature	Small/Base/Large/Giant	Mono-Large	Metric-Large	Nested
Sky Segmentation	❌	✅	✅	✅
Camera Conditioning	✅	❌	❌	✅
Multi-View Attention	✅	⚠️	⚠️	✅
3D Gaussians	✅*	❌	❌	✅*
Ray Maps	✅	❌	❌	✅

• ✅ = Fully supported
• ❌ = Not available (returns zeros/ignored)
• ⚠️ = Works but no cross-view attention benefit (images processed independently)
• ✅* = Requires fine-tuned model weights (placeholder in current release)

Choose your model based on needs:

• Need sky masks? → Use Mono/Metric/Nested (required for V2-Style normalization)
• Need camera conditioning? → Use Main series or Nested
• Processing video/multi-view? → Use Main series or Nested for consistency
• Single images only? → Any model works

Workflow Tips

For ControlNet Depth Workflows

1. Use Mono or Metric models (they provide sky segmentation)
2. Set normalization_mode to V2-Style (default)
3. Connect the depth output to your ControlNet node
4. Enjoy clean depth maps with proper sky handling!

For 3D Reconstruction (Point Clouds)

1. Use any model (Mono/Metric recommended for sky filtering)
2. Set normalization_mode to Raw
3. Connect depth → depth_raw, confidence → confidence, sky_mask → sky_mask to DA3 to Point Cloud
4. Sky pixels will be automatically excluded if sky_mask is connected
5. Important: Point cloud nodes validate input and will raise an error if normalized depth is detected (prevents incorrect 3D output)
