Hi Everybody,

I've made numerous adjustments to my night lighting that worked out just fine, but I am having an issue adjusting older lights. 

Is there an easy way to reduce the light spill from both landing and Taxi lighting via script?

Hi,

I'd ask on their discord channel, but their ottobot has turned that site into a joke for anyone looking for serious help!!

Well, I don't know which version you mean, but I would search for ‘lights’ in the DataRefs (DataRefEditor) and then maybe for strobe etc. or similar values – and give it a try! 

The sections that are above are what is being used, I just can't figure out how to reduce the spill.

I'd read https://developer.x-plane.com/article/lights-txt-file-format/ and start playing with the spill related parameters.

And you should maybe ask on XP.org as well, because of greater developer traffic.

Two options depending on what you're after.

Per-aircraft: Find the OBJ file and look for LIGHT_PARAM lines referencing airplane_landing_sp / airplane_taxi_sp. The SIZE and WIDTH values there are what you want to dial down.

Global (lights.txt): In those SPILL_SW lines, reduce WIDTH to narrow the cone. For the bloom, the flare BILLBOARD_SW lines with -28.57 / -27.574 are the big ones.  Pull those closer to zero and the flare shrinks way down.

Thanks GoranM, I'll have a look!

The obj file is the one I'm looking for, that worked out just fine.

Thanks again!
