Developing and Debugging BlendLuxCore
BlendLuxCore (BLC) is in two parts:
- Python module
- Underlying pyluxcore library, brought by a Python wheel
In normal life, Blender loads the BLC Python module that has been regularly installed, which in turn loads the wheel from PyPi.
However, when developing BLC, we typically need to:
- Have Blender load a development version of BLC
- And optionally have BLC load a development version of the wheel
Those goals can be achieved via 2 environment variables:
BLC_DEV_PATH: path to the development version of BlendLuxCoreBLC_WHEEL_PATH: path to a development version of the wheel
We'll see the use of those variables through several scenarios.
Prerequisites
We assume you have set a development environment on your local computer with:
- a cloned version of BlendLuxCore
- and optionally a cloned version of LuxCore
We also assume you know how to build an installable package for BlendLuxCore:
cmake -S . -B out -DCMAKE_BUILD_TYPE=Release cmake --build out
Scenario #1: Working on BLC, using the standard wheel
In the environment where you run Blender, set BLC_DEV_PATH to the path of your dev repository:
export BLC_DEV_PATH=/path/to/BlendLuxCore.
Run Blender.
