Make 3D assets generation in ComfyUI good and convenient as it generates image/video!
This is an extensive node suite that enables ComfyUI to process 3D inputs (Mesh & UV Texture, etc.) using cutting edge algorithms (3DGS, NeRF, etc.) and models (InstantMesh, CRM, TripoSR, etc.)

Can be installed directly from ComfyUI-Manager🚀

• Pre-builds are available for:
  • Windows 10/11, Ubuntu 22.04
  • Python 3.10/3.11/3.12
  • CUDA 12.1/11.8
  • torch 2.3.0+cu121/cu118, torchvision 0.18.0+cu121/cu118
• install.py will download & install Pre-builds automatically according to your runtime environment, if it couldn't find corresponding Pre-builds, then build script will start automatically, if automatic build doesn't work for you, then please check out Semi-Automatic Build Guide
• If you have any missing node in any open Comfy3D workflow, try simply click Install Missing Custom Nodes in ComfyUI-Manager
• If for some reason your comfy3d can't download pre-trained models automatically, you can always download them manually and put them in to correct folder under Checkpoints directory, but please DON'T overwrite any exist .json files
• Docker install please check DOCKER_INSTRUCTIONS.md
• Note: at this moment, you'll still need to install Visual Studio Build Tools for windows and install gcc g++ for Linux in order for InstantNGP & Convert 3DGS to Mesh with NeRF and Marching_Cubes nodes to work, since those two nodes used JIT torch cpp extension that builds in runtime, but I plan to replace those nodes soon

• For use cases please check out Example Workflows. [Last update: 01/August/2024]

  • Note: you need to put Example Inputs Files & Folders under ComfyUI Root Directory\ComfyUI\input folder before you can run the example workflow

• Stack Orbit Camera Poses: Automatically generate all range of camera pose combinations

  • You can use it to conditioning the StableZero123 (You need to Download the checkpoint first), with full range of camera poses in one prompt pass

  • You can use it to generate the orbit camera poses and directly input to other 3D process node (e.g. GaussianSplatting and BakeTextureToMesh)

  • Example usage:

    
    

  • Coordinate system:

    • Azimuth: In top view, from angle 0 rotate 360 degree with step -90 you get (0, -90, -180/180, 90, 0), in this case camera rotates clock-wise, vice versa.
    • Elevation: 0 when camera points horizontally forward, pointing down to the ground is negitive angle, vice versa.

• FlexiCubes: nv-tlabs/FlexiCubes

  • Multi-View depth & mask (optional normal maps) as inputs
  • Export to 3D Mesh
  • Usage guide:
    • voxel_grids_resolution: determine mesh resolution/quality
    • depth_min_distance depth_max_distance : distance from object to camera, object parts in the render that is closer(futher) to camera than depth_min_distance(depth_max_distance) will be rendered with pure white(black) RGB value 1, 1, 1(0, 0, 0)
    • mask_loss_weight: Control the silhouette of reconstrocted 3D mesh
    • depth_loss_weight: Control the shape of reconstrocted 3D mesh, this loss will also affect the mesh deform detail on the surface, so results depends on quality of the depth map
    • normal_loss_weight: Optional. Use to refine the mesh deform detail on the surface
    • sdf_regularizer_weight: Helps to remove floaters in areas of the shape that are not supervised by the application objective, such as internal faces when using image supervision only
    • remove_floaters_weight: This can be increased if you observe artifacts in flat areas
    • cube_stabilizer_weight: This does not have a significant impact during the optimization of a single shape, however it helps to stabilizing training in somecases
