Cannot compile ZED Unity LiveLink Fusion sample – BODY_70 / BODY_70_BONES undefined

Software
1

Context

I’m integrating multi‑camera body‑tracking into a Unity project.
Hardware: two ZED 2i cameras.
I’m following the ZED Live Link for Unity sample.

Steps already taken

  • Unzipped SenderTools.zip
  • Ran fresh out‑of‑source build
rmdir /s /q build
mkdir build & cd build
cmake .. -G "Visual Studio 17 2022" -A x64
cmake --build . --config Release
  • CMake finds CUDA 12.2 and the SDK in
    C:\Program Files (x86)\ZED SDK
    config & generate succeed.
  • Compile fails in GLViewer.cpp with BODY_70 errors (full snippet below).

Hi,

It seems like you are using an old version of the live link sender which contains deprecated features.

Can you try again with the latest version available on github? Release v4.2.0 · stereolabs/zed-unity-livelink · GitHub
