So I've had this on many maps, and I was always under the impression it was (mostly) caused by a patch with bad LMAP, since once I fixed the offending patch, it went away, but in a recent project I am working on it seems to be persistent.

I'm really curious of several things:

1. What tf causes it?
2. Can I ignore it?
3. Is it possible to fix it?

I've created several maps with nothing but worldspawn KVPs and without the KVPs for worldspawn it goes away, and with, it stays, so I'm not sure what is causing it.

On Garage I never had it, on Kenaven it happen once but read above, and on these new maps I'm creating it's happening when the sundirection kvp is entered.

Here's what I'm talking about:



EDIT: I also should note on any of these maps as I move away from 0,0,0 in Radiant it goes away too....

i had the same, never figured it out

Lighting directions?

Lighting directions?

I've tried 5 sets of stock settings + setting it to 0,0,0.

Nya, no idea 

I've had this before and never found a fix. I actually always used to get this on the setup map from ugx script placer.

I'm having it aswell in my mansion atm .

Pretty sure it can be safely ignored.

i have had this, its never caused problems for me
