Doom with PBR materials

How do these look ingame? I don't know what these PBR materials are, do they reflect, does lighting show on them as if they aren't flat or what?

[therektafire]

I assume you can add more advanced materials to your textures now like normal maps and specular/reflection maps to make the textures look more realistic... or well at least as realistic as a doom texture is going to look

[Stealth Frag]

PBR allows you to achieve physically compatible materials based on scanned values like IOR, roughness/glossiness, specular reflection. So this is exactly what we see in modern game engines like UE4 o CE5. And yep - this is now working with Doom xD

Sounds cool.  Is it similar to when working on 3D texturing when using "procedural textures" vs image textures?

[Stealth Frag]

Nah, that's a different cup of tea. In PBR you can use scanned surfaces or make all maps by hand, so it's nothing procedural here. Take a look at small example how it works in GZDoom: 

 

and not PBR, but also normal/spec using:

Woooo that is Doom?1?1?1 ;)

[KVELLER]

This is insanely cool :D I'm looking forward to see what people do with this in the future.

Now someone can create Doom 5 in GZDoom.

I would like to see this with unfiltered, low-res textures.

Some guy already did it https://www.facebook.com/chris.legasse/videos/10155591753028892/

That looks way better. I just don't get this HD aesthetic, it doesn't work with Doom.

[Deleted_Account]

This looks incredible! 

[Pegg]

Any mirror for that facebook link? says it doesn't exist to me for some reason.

[Stealth Frag]

@Pegg sorry - probably it's visible only for group members.

Anyway - new star material:

I would like to see a little proof of concept map for this new stuff :D

[Liberation]

This is all total madness, in a good way!

 

While I'm not sure it works for doom itself, if you wanted to make a very nice looking FPS PC game then that point is irrelevant, surely time for the first (recent) commercial game based on the doom engine?

[ZZYZX]

As for a proof of concept map, there's this actual project by some Russian ppl going on that has heavy use of the new material system in GZDoom, called Doom Slayer Chronicles:

 

 

From what I understand it's still in alpha/beta state, so all bugs and weird English seen in the video will probably get fixed in the release :P

 

(btw: Doomworld fix font sizes when? Had to scale page down to 70%...)

That looks interesting, we're gonna see some cool shit coming out. That viewbob though, jeeeesus...

[CaptainManiac]

That is UNREAL

[Stealth Frag]

A small example how it looks when all you have is barely diffuse+normal map. So, now imagine how it would look like with roughness, metallic, ao and spec.

We only need 3d monsters now.

[hoover1979]

I just wish I knew how to make normal maps for my textures. 

[therektafire]

I *think* there are programs that can generate them for you, I've heard xNormal and CrazyBump are pretty good for generating material maps but i haven't tried them myself personally

3D monsters look bad. I think we need to have really really smooth animations and randomised animations, too. Like a Smooth Doom Deluxe.

 

And voxelised items and switches, things like the awesome weapon pickups that Blood has (floating and rotating)

[Tea Monster]

3D monsters, properly done, do not look bad. They just don't look like sprites, which they shouldn't do. 

 

What model format does GZDoom use? If it's still the horrifically deprecated MD2/MD3 format, then, as someone once said, "This will be a real short trip" as far as monster models using PBR textures are concerned. 

 

You can get an open-source bump creator app called AwesomeBump from here: https://github.com/kmkolasinski/AwesomeBump

You can feed in textures and it does a pretty good job of creating normal and displacement maps from 'flat' textures.

I wish I was able to use those cool PBR effects with low-res textures...

The model could look good, but the in-game animations would still look bad because sprites kind of hide how monsters instantly rotate and move always in the same eight directions.

 

To make 3D monsters look good in-game, you'd also need to rewrite their movement and animation routines. Which means the changes have to go beyond the purely aesthetic.

Can ZScript be used for custom monster AI? I guess some minor changes, to act similar to newer games like Quake, can be done without changing the game radically.

Little update of startan3 model and material in my first post.
