godot_openvr: Unable to see VR controller in godot_openvr demo

Running Ubuntu 19.04 + nvidia 418.56 + godot on the 3.1 branch, I compiled godot_openvr via

git clone --branch master --recursive https://github.com/GodotVR/godot_openvr.git godot_openvr
cd godot_openvr
cd godot-cpp
scons platform=linux target=release generate_bindings=yes bits=64
cd ..
scons platform=linux target=release

and launched the demo via

cd demo
godot
# godot -e # I also tried launching the demo via the editor

The demo looks like this:

but I am not able to use HTC Vive controllers. FWIW I also see a constant stream of

ERROR: find_by_type_and_id: Condition ' p_tracker_id == 0 ' is true. returned: __null
   At: servers/arvr_server.cpp:305.

in the console. If I try to run the demo again (running pkill godot first), the demo launches the same except not in my HMD (I only see it in “pancake mode” in the window):

sometimes followed by a popup

Note that I only see the table in front of me in pancake mode, not in the actual VR demo.

Yeah that looks like the crash that was present during the rewrite to godot-cpp, and was later solved, as far as I know.

I suspect either the index of the material is wrong or the material is not loaded yet - or correctly. Let me see if I can reproduce this somehow (I did update my branches to current master + what godot-cpp version was linked there on Monday).
