Yea that does look usable indeed! Sign me up for that :) 

In the words of Daz, "you are a fuck". 

Aye that's the biscuits, nice one :) 

awesome! 

"and presumably quadruple the face count, but i'm guessing no-one cares?"

I guess it depends on the end result. If it looks good enough, it might be worth it. 

i've got this error
what gives?
dp engine http://quaketastic.com/files/screen_shots/dp_error.png 

Does it work in a normal Quake engine without mods? 

i guess it's somewhat related to an fte compiler, with its all optimization turned on

i'm just wondering what the hell is vm_vlen 0/1 

basically, when i'm running quake/mod via fitz(for example) it runs fine
when i'm running quake via dp it runs fine,

and when i'm trying to run the mod using DP, it crushes (vm_vlemn) 

qc bug.
vm_vlen is DP's internal name for the vlen builtin. the error is complaining about:
foo = vlen();
when the qc should have done something like:
foo = vlen(somevectorhere);
any modern qc compiler will generate a warning for that, so stop ignoring warnings and actually fix that stuff!.. whoever's qc mod that is... 

It should be fun playing with that, can't wait to see how it will affect future quake maps. 

Hell, any older map as well. You can always re-light any .bsp. You just can't change the individual lights, but anything usable in the light.exe command line is fair game. 

Here's the experimental build of tyrutils light with the -dirty option hacked in! The light.txt explains all of the new flags.

There is macos trash inside the zip 

Holy crap ... this is awesome! Looks great. Now I want to recompile all my maps and re-release them...

Thanks Eric!

That's with the -dirtydebug flag only. No lighting. LOVE THIS. 

You are a god :)

I just ran a pass on my jam3 level and it works great. I need to play with some of the options as the effect seems very subtle by default, although jam3_daz is a pretty dark map so maybe that is it.

More testing required! But I would say it's ready for everyone to use right now. 

DaZ - Abandon all subtlety. :)

-dirtscale 2.0 (or higher!) 

Would spotlights on critical points + decent minlight + AO pass be good enough? 

Well slap my salamander - that's an incredible effect 

I understand "dirty" is a not-really-AO version of AO - how exactly does it differ? Because it sure looks like AO to me. 

 

Yes sorry I got confused with the q3map3 "-dark" feature, which was the half-arsed version, not this one.

Good good. Just a silly name for it then. 

Source-code not included though? Or am I missing something. 

hogsy, it is a diff against a git revision.

Are the original id1 wad files somewhere? I wanted to re-compile all the maps to try this but got a lot of missing textures when I used wads from my collection.
