Vrad.exe keeps crashing when compiling. - Developers

I'm trying to compile my map and it always crashes on the first . after the 2 on the visleafs part. I believe it also is stopping any light updates because my map is on full bright in game even though I have a light_environment. My map has no errors and has no leaks so I have no idea whats going on.

Increase lightmap scales on faces that don't require as much lighting detail.

Its a build map so I basically made all the brushes have a lightmap of 25, is that a good number?

If VRAD doesn't crash.

It made it to 9 this time. :( I don't have to do this to the skybox walls right?

I'm having the exact same problem as you, with the exact same suggestions. Alongside with wondering if I should change the lightmap scale on skybox walls like you asked, does anyone have suggestions for what lightmap scales should be used where? Because I pretty much use 4 on everything except for large open spaces ( like roads, parking lots, etc ) which are 8, and for distant func_detail buildings I use 32.

I just changed them to 35 and it worked! thanks terrenteller.

Low lightmap scales should be used on surfaces that require detailed lighting. High lightmap scales should be used on surfaces that are evenly lit.
