Added support for Phong on world materials. See Train for examples of such materials.

http://www.reddit.com/r/GlobalOffens…date_for_42815/

Just wanted to let you guys know.

EDIT: here's the VMT from the modified texture in Train.

Code

"LightmappedGeneric"
{
	"$basetexture" "metal/hr_metal/metal_grated_d"
	"$bumpmap"  "metal/hr_metal/metal_grated_d_normals"
	"$surfaceprop" "Metal"
	


			    "$phong" "1"
                "$phongexponent" "105.0"
                "$phongMaskContrastBrightness" "[.5 8]"
                "$phongAmount" "[4 4 4 1.0]"


		"$normalmapalphaenvmapmask" "1"
	




	//"$envmap" "env_cubemap"
	//"$envmaptint" 		"[.3 .3 .3]"	
	"$detail" 				"detaildetailconcrete001a"
	"$detailscale" 			"[4 4 4]"
	"$detailblendfactor" 	"1"


}

I have no idea what "phongAmount" or "phongMaskContrastBrightness" stands for. Hopefully we'll get some doc soon.

Hell yeah, that's great!

LATTEH · April 29, 2015 at 2:33 AM

This is something I've been wanting for a long time!

Edit: aww you can't use world reflections (env map) with phong.

leplubodeslapin · April 29, 2015 at 3:52 AM

That's so great !!!

So at first i tried to use their texture in a very simple test map with 1 light.

It didn't work : screenshot

Then i tried to add a sun light, just like in de_train :

It worked : screenshot 1, screenshot 2

Then i tried with a custom texture of my friend Wenceslas :

it's pretty nice : screenshot 1, screenshot 2

I noticed that the alpha mask that was in the normalmap was used for the phong, the marble reflected more than the wood which is pretty nice.

After that, i tried to use it on a displacement :

Yeah it works ! screenshot

Then i tried to add the world reflections with cubemaps and it works great as well for me

screenshot

So i don't know what's not working with you LATTEH, can you explain me a bit more ?

And finaly the most crazy test : displacement with a texture with transparency, phong, normalmap and specular

With $translucent : http://i.imgur.com/5AjUwVz.jpg

With $alphatest : http://i.imgur.com/KxEMVks.jpg(even better since you have the shadows and the edges are sharper, more defined than with $translucent)

I'll try the other parameters tomorow, i have to go to bed it's late here

Thank you valve guys

New test:

1 bumpmap

2 Bumpmap

http://images.akamai.steamusercontent.com/ugc/7141620562…9618099EA632BD/

2 Bumpmap Lowered the second scale

did some tests

just a warning, phong and blend textures along with blendmodulade don't like eachother

Vaya · April 29, 2015 at 2:45 PM

That looks amazing!

EddieLTU · April 29, 2015 at 3:46 PM

did a test with a dust 2 tile texture

How did you get CSGO's tools mode working? I thought it has been broken since release

TheGuma · April 29, 2015 at 4:06 PM

Been messing around as well

Could do it a bit more subtle, just showing off what a single brush an a texture can do.

add -nop4 before -tools -console

and in console, type "toolload vmt"

3 years after release, they are still broken

But as nico said, you can load all the tools with "toolload" and unload them with "toolunload" (toolload vmt for material editor, toolload pet for particle editor and so on)

Thanks everyone who took the time to test this nice feature and post results, much appreciated

How does phong exactly work and could you give a Noob explanation

https://developer.valvesoftware.com/wiki/Phong_materials

https://en.wikipedia.org/wiki/Phong_reflection_model

To put it simply, envmap reflect world, while phong reflect lights. You don't need cubemaps to use phong, so there's no artifacts related to cubemap resolution. The reflection is pixel perfect. I know world is essentialy light and lights are actually rendered in cubemaps, but I think you get the point.

There's a bit more to it, phong shading is per-pixel lighting, goureaud is per-vertex, and flat is per-triangle.

I'm not sure how source handle models lighting. I guess phong is used if you put $phong in the VMT, otherwise goureaud is set by default. World surfaces are not lit per-pixel, or even per-vertex, because they use lightmaps. Only the reflections matters here.

Correct me if I'm wrong, but I think the world lights are rendered in lightmaps?

Of course! They just happen to be rendered in cubemaps as well.

At least, that's how I think it is. When you build cubemaps you can see some glows where lights should be, and you can actually see lights in some reflections in-game. It wasn't like that in previous version of the engine by the way.

leplubodeslapin · April 29, 2015 at 7:02 PM

Yes, what you can do by the way to see the glows, is lowering your screen resolution (for example 1280x720) and choose a cubemap resolution in your map that is too high (256 x 256 for example should be too much). It won't be able to build the cubemaps and there will be an error message in the console. But still, the glows will then be visible ingame.

It's a bit useless but yea, whatever. I'd like to be able to change the scale of this glow in order to make big blurred reflections with cubemaps but i don't think you can do that.

TheGuma · April 29, 2015 at 7:10 PM

So lets sum this up, Phong looks BETTER on large surfaces in my opinion.

It looks smoother, shinier. But what about performance? Is this method more performance efficient than cubemap reflections? Should I use it sparingly?

I'm very curious, as this could radically increase my map's graphical fidelity.

I'm actually expecting 3kliskphilip to do an analysis on phong

TheGuma · April 29, 2015 at 7:33 PM

It's quite weird, we were talking about this in the chat 2 weeks before this update came out.

We were looking for ways to make a texture reflect light on a world brush rather than a model.

Two weeks later, Valve out of nowhere

Do we have an undercover Valve employee here?
