Custom Shadows Hlrad Hack

hullu · December 2003

<div class="IPBDescription">Changing color of light for some areas..</div> Well I did this hack year ago and it was going to be in MHLT 1.7.1 but it didn't get released. This hlrad hack allows you to change color of light before it hits wall by placing color changing BSP entity(s) between wall(s) and lightsource(s).

here's download link to new hlrad.exe:

And here you can see what you can do with customshadows (example map sources included):

I can make maps in the style of Mondrian!

you may want to see if cagey will ship you a copy of his p13 source so you can add this there. I don't know how much use this would see in NS specifically, but people from all kinds of mods are using those tools and it would make a nice addition for some other mods.

I guess it would fit in with a funmap or circus mode, nice coding by the way.

BlackPanther · December 2003

Very nice!
Makes it way more realistic imho.

Isn't this the same as the custom shadow params in zhlt? <img src='http://www.unknownworlds.com/forums/html/emoticons/tounge.gif' border='0' style='vertical-align:middle' alt='tounge.gif'>
It looks very nice and i hope to see a good use of this <img src='http://www.unknownworlds.com/forums/html/emoticons/biggrin.gif' border='0' style='vertical-align:middle' alt='biggrin.gif'>

I'm no mapper, nor am I experienced with this stuff. But after taking a look at the pics, the whole thing is looking quite promising. <img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'>

It a very surprising light effect,could you explain it a bit more ? (without being too supertechnical plz) <img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'>

Vahn_Paktu · December 2003

I think a window has some parameter. Set it to a color. Then when the light goes through it, the light changes to that color.

Cagey · December 2003

Is this a refinement of the custom shadows in the HLRAD source distribution of 1.7?

I haven't looked at your source, but it seems like Merl had already placed some of your colored shadow code in what he made available to the public:

</span><table border='0' align='center' width='95%' cellpadding='3' cellspacing='1'><tr><td><b>QUOTE</b> </td></tr><tr><td id='QUOTE'>
#ifdef HLRAD_HULLU
// Check for colored transparency/custom shadows
VectorFill(d_transparency, 1.0);
b_transparency = false;

if (*(s = ValueForKey(ent, "zhlt_customshadow")))</td></tr></table><span class='postcolor'>

If there's additional functionality that's been added, I'll roll it into p13. Either way, it's a neat addition to the tools and you deserve the recognition <img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'>

I have a question. Would it be possible to make a hack that causes light to pass through the blue part of func_walls set to "Solid" rendermode? So like, if there was a railing, it would cast a shadow more or less kinda shaped like the railing texture? I guess you'd have to hella reduce the -chop value to make it look any good, but is it at least possible, in theory? Seems like it should be, but I could be wrong.

BigD · December 2003

Hmmm...

That would certainly be fun to play with. Some nice lighting effects could be made with that.

Reese · December 2003

Warpzone: I think the code actually applies light values to the face as a whole, then the game engine strips out anything 255 0 0 on a properly set entity. So, I don't really think it's possible. (that said, I don't know the half life source all that well, but the way I mentioned here seems like the cheapest one processing-wise) It might be better if we could get a rendermode-shadow setting that would render everything that was all blue as 255 0 0, and everything else as all black with light values applied. Then you could fake it at the cost of an additional entity using the same texture 1 unit from the floor/wall/whatever you are casting a shadow on.

That would be awesome but i think it would be quite CPU expensive. First it needs to find out the scale of the texture and stuff like alignement and then check if this is a blue spot and then send light through it <img src='http://www.unknownworlds.com/forums/html/emoticons/smile.gif' border='0' style='vertical-align:middle' alt='smile.gif'>

This latest version was going to be included in never released mhlt 1.7.1.
1.7 has old version of this, new version is 1000-10000 times faster than old code and has RGB bounce light.

I'll update p13 to the new version.

its sweet!!!
the window: each "shadow" needs a seperated brush, right? uhoh *thinks about maxnumber of entities*

BlackPanther · December 2003

The "light only through the blue parts" has been done before in a now dead mod called UNCROSSABLE PARALLEL... iirc... cuz i damn well remember a pic

Belgarion · December 2003

*nod nod* this is indeed cool.
now if you can get rad to let light go through those and the resulting light on the wall to be colored as the texture.... i'll be real impressed then

separate brush? no.

You can group brushes to one entity normally (multibrush blue glass that is one single entity making for example).
