Sorry for the late reply – the issue was that the MRT collision implementation was missing the any_platform macro that is needed to trigger device code generation (and unfortunately nvcc silentlly produces garbage instead of failing). I pushed an update to the release repository. In my tests aorta3d now works with MRT on GPUs.
