How to make interior lights work for your custom car
To make interior lights work, you first need to create the light boundary/shape which will contain the interior light. This is defined in an entLightChannelComponent in your vehicle's ent
For eg in the porsche 911 .ent:
To create this shape, first we need to create a "cutout" of the interior mesh. Load your car's interior in a Blender project and join them all into a single mesh
Then you can create a cutout mesh by overlaying an Icosphere over your car's interior mesh and then using a Shrinkwrap modifier as shown:
Ensure the final cutout isn't high poly. Realistically, you don't need more than a few hundred vertices at maximum. High poly cutout may cause game crashes
Once you have your cutout mesh, use this script to generate the indices and vertices for wolvenkit: https://gist.github.com/misterchedda/aa730fab5bc0aa0f1bd905f617c84e6d
You'll need to convert the .ent to JSON in wolvenkit, replace the indices and vertices array with the output of that script
Then you can convert the JSON back to .ent in wolvenkit
That's it! Like other light stuff (such as brake lights or headlights covered in other pages) - ensure you have an entLightChannelComponent in your .app parented to the interior.mesh (or whichever mesh has the interior light mesh + vehicle_lightsmaterial + vertex colors assigned )
