Okay, you're probably right. The picture was so dark I couldn't really see anything other than the white and blue blobs, and I was too lazy to turn the gamma up. 

White and colored lights shouldn't have vastly different intensity / falloff, and if anything white will be brighter than colored as Rick was saying.. so something is wrong here.

Is the "_color" key set on the white lights (the dim ones on the right)?

The engine's brightness/contrast controls are blowing out the colors so it's hard to tell what's going on. Also assuming that is Darkplaces, you can view the lightmap only by entering "gl_lightmaps 1" in the console. 

It's clearly amplifying the light instead of reducing.

Somehow, it seems to be adding the color to the light instead of multiplying. 

It's Darkplaces. Only the color lights have "_color" key. I'm at work right now but AFAIR I didn't use any "_deviance".

If anyone wants to check it, I could take more screenshots with higher brightness or should I mess with any other parameters?

I'll check the same settings in FitzQuake and will let you know. 

Use floats, ie values between 0 and 1.
Values greater than 1 will either oversaturate or be divided by 255, depending on implementation (welcome to the wild west).

The lighting in that screenshot actually has nothing to do with tyrlight[-ericw], because the engine you're using is basically ignoring its output and making up its own thing based on the map entities.
set r_shadow_realtime_world 0 to get it to behave properly. This'll also boost framerates significantly, so a double win...


ericw, how about a feature to ignore/strip certain lights so you can more easily set up rtlights without damaging static lights? maybe 

Loathe as I am to suggest continually adding fudges to support all the different implementations custom engines expect - on the compile side, would it make sense to always normalise 0-255 values into 0-1 values when saved to the bsp? 

I've updated my FGD file for version v0.15.9 of Ericw tools so you can now set phong on brush models and projected textures on lights.

Tested with J.A.C.K steam release 

Spike, ah, rtlights explains it. Hmm maybe a key to omit an entity from the bsp could be handy, although in this case the mapper could just use colors values in 0-1.

I kind of hate to add hacks like scaling the "_color" values in the bsp to 0-1, although I suppose it improves compatibility with darkplaces "auto-rtlights" and should be pretty safe. 

Thank you Spike! As soon as I changed the values into floats, the light got rendered nicely.

Also, when I turned off rtworld, as suggested by EricW, the rendering was pretty close to how FitzQuake does it. Although, I do have to admit it, it's a bit bland this way.

If anyone wanted to check a poor presentation of the above, go to https://flic.kr/s/aHskVVmHss. 

Got this error when working on my map, after I made a brush that was way too finely curved for its own good. Is there any solution other than just having rough edges? :( 

Csg Split it into several smaller brushes? 

More than 64 verts will crash most Quake engines, since engines also contain code that assumes that the max verts in a face is 64. Example: https://github.com/id-Software/Quake/blob/master/WinQuake/gl_warp.c#L148

So you definitely want to keep the tools error and correct your brush instead. 

Can't the BSP compiler split such brushes automatically? 

New beta:
https://github.com/ericwa/tyrutils-ericw/releases/tag/ericw-v0.15.10-beta1

Has the .map conversion feature in qbsp, so you can do:
qbsp.exe -convert valve mymap.map
and it will write out a copy of the map in Valve 220 format to mymap-valve.map. It can also convert to "quake", "quake2", "bp" (quake 3 brush primitives).

I labelled it "beta" because it's not tested enough, light has a large change to how sample points are positioned. (so unexpected black faces should never happen any more, e.g. this) 

so unexpected black faces should never happen any more  

at least one of the causes is gone. 

I think you may have added in a cause:
0.15.9
0.15.10

Also, would it be possible to turn off the bouncing for styled lights with an option? It's causing a lot of "too many lightstyles" warnings on my map.

In more positive news, converting my map seems to have gone off without a hitch! :D 

So it's the black artifacts around the floor tiles? Was that shot with -extra4? I should be able to reproduce it.

re: bounce, good point, it should be opt-in, I guess. "_bounce_styled" "1" worldspawn key?

Thanks for testing and glad the .map conversion worked! It should be pretty trouble free because all the brush planes are passed through losslessly. 

No, no -extra4 or soft. I haven't been using those parameters as I test the map. If you like I can create a github issue with the .map and perhaps a compiled .bsp/.lit? I did just try splitting off the problem area into its own map but I couldn't even reproduce the exact lighting I have... 

Sure, or just emailing me the .bsp + .lit is fine too. I was just trying to reproduce it now. 

Also, interesting tidbit but nothing of any real issue: Converting the map to valve format through your tools seems to have reversed the order keys are listed in for TB2. Classnames are now at the bottom rather than the top. Not the case for newly created entities of course. 

thanks for noticing that, should be harmless but I'll fix it! 

Can sunlight be assigned a lightstyle? Thinking it could be cool to fade it in/out via QC. 

It's really easy to add though, i'll add it after fixing Pritchard's issue. 

Can sunlight be assigned a lightstyle?

Man that could open up some interesting visuals.
