Nice, now I'm going to spend the next few hours figuring out how to do it myself haha
I found the line to enable antennas
For every camera, there is this line:
<Parameter name="highResInterior" type="bool" value="true" />
If you change it to
<Parameter name="highResInterior" type="bool" value="false" />
You should get antennas back. I tested it with the Red Bull t-cam, it works. I don't know any adverse effects with disabling highresinterior, I'll check it out. I couldn't have found it without Amfion's tips, thank you very much
