Hi!
I'm working on a tram that has passenger lighting like this:
What I don't really know is what's the "best" method for adding lights like this. On my previous vehicles I simply added this many point sources, but that's not very performance efficient, and even with a few lights I got light flickering bug.
There are about 40 lightbulbs, in two sections (one can be turned off when the other is on, and of course they are separated in a zig-zag pattern), so adding all as individual point sources is quite bad. But if I give invisible bar lights (one for each department) with varying intensitiy (according to the number of sections ON), the zig-zag pattern is lost (though not like it was visible really in LOTUS). Should I use this very basic lighting with maybe some effect on the ceiling texture (like in OMSI with the baked lights)?
