Error with expert compiling. "Can't create logfile ..."
Yeah, this is stupid. I am going for final compile with my map by using expert compiler to get better shadows, but this "Can't create logfile ..." error ruins everything.

I'm going with "Full compile - HDR only" configuration and all settings are default expet "$light_exe" commands parameters I changed to these:
"-textureshadows -hdr -StaticPropLighting -StaticPropPolys -game $gamedir $path$file"
Any ideas how do I fix this? Because time is running short. 
Hm. So it looks like VBSP is running out of memory. How much RAM do you have on your computer?
4GB
Not sure if this could cause it, but do you have lots of named lights? I know that takes up lots of memory. But, then again, its VBSP that is running out of memory, not VRAD. Is it a really big map?
Wrong. Naming lights will only increase compile time and BSP size. It will not throw that error, because that would be under the "Too many light styles on a face" error. It's a BSP problem.
It's a good thing to tie brushes to func_detail, but there is such a thing as TOO MUCH. Try removing as much func_details as you can, or convert them back to world geometry.

I have none of func_detail I could remove, otherwise visleaves would kill me. And also, I sent my map .vmf to my friend and he compiled it with exact same compile settings and it worked for him. Is it possible that I have something wrong with Hammer? 
Try validating Hammer.
Do you have lots of (large) surfaces with a low light map scale? That may be responsible for the "drastic memory overflow" error. Make a backup copy of your VMF and try setting all light maps to 16 or 32.
What I usually do as one of the final editing steps for a map, is set all of the light maps to 32, and then selectively lower the number on surfaces where the lighting looks odd or where there's lots of shadow detail.

^ yea, because it's generally a rule of thumb to optimize lighting *last* in the mapping process
Hi,
Think I can see what is wrong from your log.
I recon there is a 'Carriage-Return' on the end of your $light_exe parameters. You must have pressed return on the end or copy-pasted it in when you changed it.
If you select the parameters when on light_exe, see if the cursor goes onto the 2nd line if you cursor to the end of the parameters... and then press delete once.
You can see in the log on the last line, that it looks like there is a CR between the log filename and the '.log' that gets added. Thats what made me guess it...
That should fix it I recon...
Rob.
