Creating digital gauges

I've been looking through ETK files to try and understand how digital gauges are done, but I'm stuck. I know how to create an HTML gauge cluster and do the js, but I don't know how to map it as a material. How would I do that?

 

Hi @SushiPro ,
I think this process lives in BeamNG.drive\lua\vehicle\material.lua:updateGFX(). This function fetches the electric values and first checks which values have been changed and wich not (ll.229-244).After that it checks how high the value is and determine which material should be used (newMat = va.on or newMat = va.on_intense) (ll.244-274). If a material was found it applies the new material (ll.274-285).I think the real interesting lines are 280 and 282. With these commands you should can replace your material in you own script. The first parameter for the switchMaterial-function is I assume a numeric id (I´m not 100% where the id is coming from) and the second parameter is the material name. You may also have a look into the function switchMaterial(msc, matname) declared in line 32.
Example: ETK I 2400ti TTSport Evolution -> VehicleLua: obj:switchMaterial(2,"etki_lights_on") switches one of the booster lights to white.
I hope that helps you .
