Building usdtweak

Requirements

The project is almost self contained and only needs:

  • cmake installed (version > 3.14)
  • a C++17 compiler installed: MSVC 19 or 17, g++ or clang++.
  • a build of Universal Scene Description version >= 20.11. In theory the USD libraries provided with mayausd should work but they are not tested, let me know if you manage to compile with them.

To compile usdtweak you normally need to provide cmake with only 1 required variables:

  • pxr_DIR pointing to the USD installation directory containing the file pxrConfig.cmake

Unfortunately if you have compiled USD >= 22.08 with MaterialX you will also need to provide:

  • MaterialX_DIR pointing to the MaterialX installation directory containing the file MaterialXConfig.cmake.

Compiling on linux

On linux it should compile with:

git clone https://github.com/cpichard/usdtweak
cd usdtweak
git checkout develop
mkdir build
cd build
cmake -Dpxr_DIR=/path/to/usd-24.08 ..
make

If you have USD >= 22.08 compiled with MaterialX, cmake becomes:

cmake -Dpxr_DIR=/path/to/usd-24.08 -DMaterialX_DIR=/path/to/usd-24.08/lib/cmake/MaterialX ..

Compiling on MacOs

It compiles on MacOS Monterey. The viewport is now enabled for versions of USD superior or equal to 22.08, otherwise it is deactivated as the OpenGL version is not supported on MacOS for those versions.

git clone https://github.com/cpichard/usdtweak
cd usdtweak
git checkout develop
mkdir build
cd build
cmake -Dpxr_DIR=/path/to/usd-24.08 ..
make

If you have USD >= 22.08 compiled with MaterialX, cmake becomes:

cmake -Dpxr_DIR=/path/to/usd-24.08 -DMaterialX_DIR=/path/to/usd-24.08/lib/cmake/MaterialX ..

Compiling on Windows

It should compile successfully on Windows 10 with MSVC 19 or 17 using the RelWithDbInfo config. Make sure you open/use the x64 Native Tools commands prompt before typing the following commands:

git clone https://github.com/cpichard/usdtweak
cd usdtweak
git checkout develop
mkdir build
cd build
cmake  -G "Visual Studio 16 2019" -A x64 -Dpxr_DIR=C:\path\to\usd-24.08 ..
cmake --build . --config RelWithDebInfo

If you have USD >= 22.08 compiled with MaterialX, you have to add an additional MaterialX_DIR variable to the cmake command, pointing to the MaterialX directory:

cmake  -G "Visual Studio 16 2019" -A x64 -Dpxr_DIR=C:\path\to\usd-22.08 -DMaterialX_DIR=C:\path\to\usd-22.08\lib\cmake\MaterialX ..

Using NVidia's USD build (experimental)

NVidia provides a USD build here if you don't want to compile USD yourself. We tested 2 versions, 22.11 and 24.08.

USD 24.08

This was tested on windows with MSVC2019. Unfortunatelly the configuration coming with the nvidia libraries doesn't have the correct python directories, so the cmake command is a bit more involved than with 22.11. Make sure you type the following commands in a x64 Native Tools commands prompt and replace C:\path\to\nvidia-usd-24.08 by the actual path containing the nvidia usd libraries.

git clone https://github.com/cpichard/usdtweak
cd usdtweak
git checkout develop
mkdir build
cd build
cmake -G "Visual Studio 16 2019" -A x64 -Dpxr_DIR=C:\path\to\nvidia-usd-24.08 -DPython3_EXECUTABLE=C:\path\to\nvidia-usd-24.08\python\python.exe -DPython3_LIBRARY=C:\path\to\nvidia-usd-24.08\python\libs\python310.lib -DPython3_INCLUDE_DIR=C:\path\to\nvidia-usd-24.08\python\include -DPython3_VERSION="3.10.14" -DMaterialX_DIR=C:\path\to\nvidia-usd-24.08\lib\cmake\MaterialX -DImath_DIR=C:\path\to\nvidia-usd-24.08\lib\cmake\Imath ..

Then compile with:

cmake --build . --config RelWithDebInfo

The build will fail with the following error:

LINK : fatal error LNK1104: cannot open file 'C:\path\to\nvidia-usd-24.08\lib\osdGPU.lib' [C:\path\to\usdtweak\build-24.08-nvidia\usdtweak.vcxproj]

This is because the libraries osdGPU.lib and osdCPU.lib are not included in this nvidia release, but they are listed as dependencies in the configuration. To fix this problem you'll have to edit the file C:\path\to\nvidia-usd-24.08\cmake\pxrTargets.cmake and remove all occurence of ${_IMPORT_PREFIX}/lib/osdGPU.lib; and all occurence of ${_IMPORT_PREFIX}/lib/osdCPU.lib;. Once it's done you can recompile with

cmake --build . --config RelWithDebInfo

And you should get usdtweak.exe compiled in the RelWithDebInfo folder.

USD 22.11

It needs either VisualStudio 2017 or a more recent version (2019, 2022) with the "MSVC141 - C++ build tools x86/x64" installed. The cmake commands to build usdtweak differ, if you have a more recent version you'll need to specify the toolkit using -T v141. The Nvidia USD build also needs Python3.7, set the USE_PYTHON3 argument to force cmake to look after Python3, but you'll have to make sure Python3.7 is installed already.

cmake  -G "Visual Studio 16 2019" -T v141 -A x64 -Dpxr_DIR=C:\path\to\nvidia-usd-22.11 -DMaterialX_DIR=C:\path\to\nvidia-usd-22.11\lib\cmake\MaterialX -DUSE_PYTHON3=ON ..
cmake --build . --config Release

Using Houdini's USD build (experimental, only Houdini 20+ on Windows)

First make sure there is no USD and Python path in the environment variables. Open a houdini command line shell, inside the shell, create a build directory, like in the previous example then run the cmake command pointing pxr_DIR to the cmake\houdini subdirectory.

cmake -Dpxr_DIR=<USDTWEAK_DIR>\cmake\houdini ..
cmake --build . --config RelWithDebInfo

(Replace <USDTWEAK_DIR> with the directory pointing to the usdtweak project)

Installing on Windows

You can install usdtweak with its dependencies on windows, it copies the required files in a directory with the following command:

cmake --install . --prefix <where_you_want_to_install_usdtweak> --config RelWithDebInfo

Note that it is not really tested on anything else than my machine/setup so it might not work for you, feel free to get in touch if you have any issue.

Creating a Windows installer

There is an experimental packaging system using cpack/NSIS on windows to create an installer. You have to make sure the nsis application is available on your system, you can download it from here NSIS. The command to create the installer is then:

cmake --build . --target package --config RelWithDebInfo

Compiling with your version of glfw

usdtweak is using GLFW for its windowing system. cmake should normally download, compile and install glfw without any user intervention. However, if you already have a compiled version you want to use instead, and you'll need to disable the automatic build of glfw, by passing an additional cmake variable:

  • glfw3_DIR pointing to your GLFW installation directory and containing the file glfw3Config.cmake

A cmake command will then look like:

cmake  -G "Visual Studio 16 2019" -A x64 -Dpxr_DIR=C:\path\to\usd-24.08 -Dglfw3_DIR=C:\path\to\glfw3-3.4\lib\cmake\glfw3 ..
