yeah, if you do the classic 1:4 2:4 3:3 4:2 4:1 cylinders, you will have some angles that you can't perfectly line up the textures on with whole degrees. Not noticeable until you have a long enough surface with the same angle 

I'm getting this error with my map:

light: /home/benny/Downloads/tyrutils-ericw-ericw-v0.15.5/light/light.cc:656: void CalcualateVertexNormals(const bsp2_t*): Assertion `smoothedNormals.find(v) != smoothedNormals.end()' failed.

As well as a bunch of: WARNING: couldn't nudge light in solid at -1586.848267 174.062302 507.337677

Which I assume is because some of the surface light textures cover the entire brush and some are against other solids.

This same map didn't give me errors with an earlier version. Running ubuntu 16.04.

Also, isit possible to have phong shading on non func_details, I have a func_illusionary or two I'd like to use it on.

Thanks in advance! 

Mind emailing me the .map+.bsp+.texinfo?

phong shading on any func_ should work. You have to run a full qbsp to update the .texinfo file though.

btw hoping to make a new release pretty soon 

the new version compiled and works a treat.

also the "-gamma" command is amazing, saved me having to decrease all my light values after adding -bounce 

Liquid surfaces should be completely ignored when dirtmapping, but they aren't. Here's an E1M2 screenshot.

Ideally, lit liquids shouldn't receive or emit dirtmaps. 

I've taken that screenshot with the water fully transparent, and the map was compiled with these parameters:

$bsp_exe -nopercent -splitspecial $bspdir/$file

$light_exe -extra4 -dirt -dirtmode 1 -dirtgain 0.875 -dirtscale 1.5 $bspdir/$file 

 

"_dirt" "n"
For brush models, -1 prevents dirtmapping on the brush model. Useful it the bmodel touches or sticks into the world, and you want to those ares from turning black. Default 0.
Maybe it will work with water brush too? 

I've just tried it, and _dirt -1 doesn't work on func_detail. 

Well, actually _dirt -1 sort of works on func_detail. The water isn't dirtmapped now, but it still casts dirtmapping in the rest of the world model. 

Thanks for the report, I will fix it properly.
Probably I'm checking for TEX_SPECIAL and skipping casting/receiving dirt if that is set, need to also check if the texture starts with
"*" or "sky" in case splitspecial is used. 

Thanks.

A little feature request: Can you add individual options for -splitliquids and -splitsky? This would be more optimal than -splitspecial, since there's usually no reason to allow sky surfaces to be lit. 

It should be there already, just called -splitturb instead of -splitliquids 

It is; I've tried it out, and it worked.

Thanks, I've updated my compiler parameters. 

Gosh I had no idea lit liquids were even supported in this tool. Any chance someone could give those quakespasm cheps a bit of a nudge?

Not really any new features, but lots of performance improvements. It's something like 2-4x faster depending on the map.

Also fixed the regression with bmodels touching the world that Kinn reported.

minlight no longer bounces

I can't even begin to imagine how that worked or looked. 

V0.15.7 isn't compiling at all here.

** Executing...
** Command: C:\Dev\Tools\tyrutils\bin\qbsp.exe
** Parameters: -nopercent -splitturb C:\Projects\QuakeDev\Game\Quake\_QDebug_\maps\E1M2

It was the 64 bits version. The 32 bits version is compiling fine. However, I'm on Win 7 64-bit. 

Maybe try installing the 64-bit version of the msvc 2013 runtime (vcredist_x64.exe)? 

 

I'll try it.

In the meantime, I've confirmed that the worst part of the dirtmapping bug is now fixed; liquids won't cast dirtmaps on the world anymore.

They still receive dirtmaps, but at least this problem can be worked around by func_detailing them with _dirt -1: screenshot. 

Wow, 0.15.7 is incredibly fast! I don't have specific times, but it speeds up light on my map by a huge amount. No idea what kind of wizardry was performed for this, but it's really cut down on the iteration time for my map. Thanks so much! 

Pritchard - awesome :)

got some bugs reported and fixed already (to be in the next release):
- the "unmatched" target warning was broken
- skip-textured func_'s with "_shadow" "1" were broken (for making invisible shadow casters)

This one was tricky due to how I migrated light away from using the BSP for raytracing. The workaround I implemented has a limitation that the entire bmodel has to be textured with "skip", otherwise the skip textured bits don't cast shadows. Hopefully this covers the common use cases for that trick, though. 

That looks pretty damn cool. How did you get the water to draw shadows like that?
