UDIMTextureImporter3

Import UDIM displacement(sculpt using maps in Mudbox), color, and mask textures.

NOTE: Windows only

Resculpted mesh vs the orignal: If everything(mesh, UVs, Smooth options, map settings, etc) are all correct and consistent, then the result should be pretty close to the original, still you may have some lines around the UV borders.

Install

Windows10/11 & ZBrush2022

1. Go to release page, download the latest and extract it.
2. Move tiff.dll, zlib.dll, and deflate.dll to the same directory as ZBrush.exe. (For example. C:\Program Files\Pixologic\ZBrush 2022\tiff.dll)
3. Move UDIMTextureImporter3_2022.zsc to ZPlugs64 folder.
4. Move UDIMTextureImporter3Data folder to ZPlugs64 folder.

So they should be placed like this

└── ZBrush 2022/
    ├── ZBrush.exe
    ├── tiff.dll
    ├── zlib.dll
    ├── deflate.dll
    └── ZStartup/
        └── ZPlugs64/
            ├── UDIMTextureImporter3_2022.zsc
            └── UDIMTextureImporter3Data/
                ├── UDIMTextureImporter3.dll
                └── ZFileUtils/
                    └── ZFileUtils64.dll

Usage

Go to ZPlugin -> UDIMTextureImporter3.

Make sure textures are in UDIM naming convention (eg. filename.1001.tif, filename.1002.exr, etc),

Supported image format

Vector/Normal Displacement

Images need to be exported from ZBrush/Mudbox.

• 32 bit tif/tiff (compression: None, and Deflate, LZW with zlib and deflate lib)
• 16 bit FP exr
• For tangent space vector displacement, textures need to be exported in the following settings.
  • Mid value 0.0
  • ZBrush: FlipAndSwitch and TangentFlipAndSwitch: 25
  • Mudbox: Absolute tangent

Color

Color import doesn't work if layer recording is turned on. Make sure it's turned off.

• 8/16 bit tiff/exr

Mask

• 8/16 bit tiff/exr

Build

Requirements

• VS 2015 or higher
• C++20
• Eigen
• libtiff
• zlib required for libtiff
• deflate required for libtiff
• tinyexr
• miniz required for tinyexr
• GoZ_SDK
• ZFileUtils

Build instruction

1. Build zlib and deflate, then build libtiff with the first two libraries.

2. Download third party libraries.

   1. Download miniz.c and miniz.h and move to src directory.
   2. Download tinyexr.h and move to src directory.
   3. Download GoZ_SDK, and move all files to sdk directory.
   4. Download Eigen and move to the src directory.

3. So the project directory should be like this.

   └── UDIMTextureImporter3/
       ├── CMakeLists.txt
       ├── build/
       └── src/
           ├── main.cpp
           ├── main.hpp
           ├── texture.cpp
           ├── texture.hpp
           ├── miniz.c
           ├── miniz.h
           ├── tinyexr.h
           ├── sdk/
           │   ├── GoZ_Mesh.cpp
           │   ├── GoZ_***
           │   └── ...
           └── Eigen/
               ├── Core
               ├── Dense
               └── ...
   

4. build

mkdir build
cd build
cmake ../
cmake --build . --config Release --target install

UDIMTextureImporter3.dll file should be generated under the project root.
