Hello William, Thanks for your interest in using Chrono for your project.
My suggestion is to figure out problem of error "cannot import name '_sensor' from 'pychrono'" and not reinvent the wheel to write your own ray tracing engine. This error likely is because the package installation sequence or CUDA installation has problem, if you want to share the error, system setup, and steps you installed pychrono package, we can help you with it (check carefully the version and sequence of installation listed here: https://api.projectchrono.org/pychrono_installation.html).
