This is intended in 01.c , it's just so something moves at all as there is nothing in the scene wink

Have a look at the end of main() and you'll see this, which will increase HDR brightness.
Or do you mean something else 3run?

Code:
while(1) {
	sc_screen_default.settings.hdr.intensity += time_step*0.01;
	if( sc_screen_default.settings.hdr.intensity > 1) sc_screen_default.settings.hdr.intensity = 0;
	
	wait(1);
}
