q3map2 light process optimization

[wedge2211]

So I go to compile my tal Erulanei map...and the light phase takes 3 1/2 hours. Yuck. I'm wondering if there are some light options I can play around with to speed this up? This map in particular is composed mainly of patches, which are crazy to light. I used this q3map2 command:

 

C:/Games/JEDIOU~1/GameData/Tools/GTKRAD~1/q3map2 -v -game jk2 -light -fast -patchshadows -filter "C:/Games/Jedi Outcast/GameData/base/maps/tal.map"

 

And this is the light process as it came out:

Any thoughts?

Try to make the virtual memory bigger

Are you almost done with your map? If so, I'd say: suck it up, fire off your compile.bat right about bedtime, and let that puppy run overnight.

 

I would offer to help you out by doing a "-threads 4" compile for you, but you wouldn't really save any time, what with having to waste time emailing files back and forth.

 

Have you expirimented with the "-cheap" flag? It, apparently, "stops Q3Map from calculating light on a sample after it exceeds (255, 255, 255)." Perhaps that might speed things up for you?

 

Sorry, don't really have any more to offer... :^\

Wow...I posted that over a month ago. And I solved the issue. And now it comes back up.

oh, oops... I didn't even see the original post date. I just noticed it on the front page of topics, I guess since Darth replied to it. In any case, I'm glad it has been resolved ;^)
