Adding Sample WASM Gauge to custom aircraft (loaded but black)

Hi there,
I’m trying to get the sample attitude.cpp wasm gauge into my custom aircraft. Right now the screen gauge stays black.

I know the actual material is linking (mouse collision is detected) but the gauge stays black although I am just using the compiled SampleModule.wasm inside the panel folder. The panel.cfg should also be correctly setup so is there something I can check?

Additionally, the wasm debug window shows that the module is loaded and active.

Also the panel.cfg documentation mentions 2 different types of gauges
htmlgauge00
gauge00
but I only see htmlgaugeXX used in examples even though the docs mention that gaugeXX is for WASM gauges. This seems contradictory to me.

For the record, I tried both and the screen stays black.

Nevermind, fixed turns out the material emission has to be white
