What are you talking about the first on looks like someones spilt Domestos(bleach) on the carpet the second one is using proper lighting and I think it looks cool? If people realy think that the additive blend looks better then I'll use that though.

Muu · February 2002

Improved the additive render some more

The second shot on the 3rd page is most convincing, but only because the edges of the illuminated areas are much more diffuse. you could probably get the very same effect by blurring the texture you are using for the additive map, so that the edges are no so defined. Also, You'll want the texture to be colored the same as your light source (ie: since the light is white above, the additive texture should be in the gray range with no coloration).

Nice work though! It's a really cool effect!

I dunno, I kinda like the first on the third page, and the first on this page. The sharp edged lights may not be realistic, but they sure do look cool. <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

I really like that effect Mu. Great work.

Relic25 · February 2002

Here's a little test room using the same effect, but offset a little and using a 'fuzzier' luminosity texture. I love this effect Mu_! I wish I had thought of it, or had heard about in time to use it somewhere. <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

While Relic's shot is much more realistic and gritty feeling, and therefor would probably suit NS better, I really like the stylish look of Mu's 1st shot on this (4th) page.

Oh man now Ive got competition <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> That shot looks sweet but I think it looks wrong(but cool) because the additive blend is just adding white to the underleing texture. Thus the effect looks more like spray paint than the texture reflexting light(Im not very good at explaining things). What ive been doing is incorperating the texture into the additive layer(this isnt easy) so that is a pixel is red in the texture it gets addother red pixel added to it making it look brighter, also by adding colouring your light mask you can add more blue or whatever to the final additive layer.

This does was developed with gama but its looks fine with out. Also I havent tryed to get the shadow cone effect right like relic has (but I will and then he'll be sorry) I hope this is of some use to other mappers - note that this effect will not light the player! and thus may look a little strange and requires a lot of time to get right.

mr_Nebel · February 2002

Yeah that definately looks good, whats the 'shadow cone' BTW?
TO clarify i thought the original first shot looked better because the second one was TOO blurry

Relic25 · February 2002

I agree with you 100% Mu_. If you're only using that effect in 1 or 2 spots, then your way is definitely the way to go. The way I did things is only a cheat for those who can't afford to make a custom texture set for each luminosity effect (because the light is falling on different textures).

Muu · February 2002

Shadow cone - I probably mean light cone or something, but the sides of the banisters and under the banister should have some light because its not going straight down it spreads in a cone shape, it would be a very hard thing to work out because it needs to be done by eye or with a prefad which fits inside the patches of light at the top and you expand at the bottom to fit the bottom patches then see where it intersects the world brushes and draw the additive texture from that.... to much work i think <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

4 meg texture limit.

Biomechanoid · February 2002

Holy crap. Those last few shots I didn't think the HL engine was capable of rendering with shadows and such.... and yet there's the NSTR2 logo slapped in the pic. I'd love to see these effects in game.

*off topic*
anyone know of a good program to layout a level on besides MS paint or using paper and pencil?

HanzGruber · February 2002

that's the way.....take alllllll the glory Mu_ <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/wink.gif" border="0" valign="absmiddle" alt=';)'>

anyway....

realityisdead · February 2002

Those last shots are amazing Mu. I am in awe. Half-Life's lighting engine may not be able to produce that on it's own like the newer engines, but wow... you really proved me wrong about not being able to make something similar looking. Thank you (seriously). <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>

And Hanz, Thank you so much for posting this topic in the first place... you have seen the results. Just awesome.

I too have started something <i>inspired</i> by the shadows in those blue shots with the computer, etc. It looks nothing like it, no fine shadows and all, but it is something I'm quite pleased with and I probably wouldn't have done it if I wasn't trying to prove myself wrong about the Half-Life/Kreed thing. Thanks <img src="http://www.natural-selection.org/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'>
