rd-rend2 (old thread)

[Tempust85]

So how much more does rend2 need to be finished minus performance tweaks? I wouldn't mind starting to produce rend2 content.

[Xycaleth]

At the moment I'm just going around and fixing minor things up. It's kind of disappointing that nobody (at least not that I've seen) has created any content for ioq3's rend2 so I'll take the leap of faith and say it's "usable" and that you can start producing rend2 content.

 

I'm still not sure how backwards compatibility will work but we'll see

[Circa]

Well DT and Ashura have been itching to create content for rend2, so I'm sure you'll get something within the week.

...and I hope to be ready for wrinkle maps within the next few months-- apologies for my lack of progress.

[Scerendo]

Oh man super excited for this, everyone working on it is doing a great job.

 

Just a quick question and apologies if its been posted already (its such a big topic I'v probably missed it : ( )

 

Was wondering if anyone has got an example for a shader that incorporates normal, specular and gloss maps, compiled?

[Boothand]

Just out of curiosity, a lightmap is still required for these to work?

 

As always, great watching more progress! Love it.

[Xycaleth]

Here's an example of a shader which uses diffuse, normal, specular and gloss:

textures/rend2/example
{
  {
    stage diffuseMap
    map textures/rend2/example_d
  }
  {
    stage normalMap
    map textures/rend2/example_n
  }
  {
    stage specularMap
    map textures/rend2/example_s // This actually holds both specular and gloss (in the alpha channel)
  }
}

I can upload example textures as well when I get home.

 

I really want to condense this down to something more concise though. Something like this perhaps:

 

textures/rend2/example {
  diffuseMap textures/rend2/example_d
  normalMap textures/rend2/example_n
  specularMap textures/rend2/example_s
}

[Tempust85]

Awesome news! I'll be doing the EP7 stormtrooper as my first piece. Just need those ghoul2 black spots removed though please.

@@AshuraDX I think set up a shader for the AT-ST so that it should use all the same maps came out of substance designer but I'm not 100% on that.

[AshuraDX]

@@minilogoguy18 I have that somewhere, yeah - needs to be altered a little to use the gloss though

will get some test models packaged up and sent your way tomorrow evening @@Xycaleth

[minilogoguy18]

Another thing, @@Psyk0Sith, do you have any displacement maps that you used to render Kain? If so I'd like to have them to see if any shader could be set up. I know, I know, I never released the model, I ran into some LOD and weight issues. Got lazy and didn't wanna release it until it was fixed but I swear once I have the time I'm gonna fix then release it lol.

Well no, since it was not baked from a high poly model, it could be faked with something like crazybump but doesn't always produce good results.

[AshuraDX]

@@Psyk0Sith instead of using crazy bump I'd trace the important features in substance painter - effectively "paint-sculpting" a normal map on the lowpoly mesh

@@Xycaleth about the rend2 gloss maps - common setup ? white is glossy, black is dull ?

[Xycaleth]

@@AshuraDX Yep, white is glossy.

[AshuraDX]

@@Xycaleth : here you go https://www.dropbox.com/s/fqz72sdesxej7ch/HUGEDL44.pk3?dl=0 as of now it's still uploading since the textures are all in 2k and uncompressed 24 bit TGAs

 

did not get the at-st ready yet  but I got the humansize DL44 done

 

includes :

DL44_rend2_d.tga - diffuse with Transparency in Alpha

DL44_rend2_s.tga - Specular with Gloss in Alpha

DL44_rend2_n.tga - Normal with height/displacement/Parallax in Alpha

I usually prefer to do real sculpts instead. Painting is better suited for surface details.

usually - yes but in this case you allready have a textured lowpoly mesh and getting details to match between a new sculpt and that lowpoly is a pain in the ass

[Xycaleth]

The DLL44 looks quite shiny. I expect it's not meant to be that shiny

 

 

 

 

 

 

But soon after I toned the values down a bit (probably not correct to do this, but as a quick hack). I expect it's because Surface Designer (I think that's what @@AshuraDX used for the textures?) uses a different lighting model from rend2...

 

 

 

So there are some extra changes I can make so it looks more correct, but it would make existing JKA assets look wrong. I need a way to make both work...

[AshuraDX]

this was textured using the Quixel DDO legacy version and should look like this

 

I usually work in Allegorithmics substance suite nowadays

 

EDIT : I also jsut remembered that the DL44 normal map has no parallax in Alpha

[Tempust85]

Parallax doesn't work on models anyways. When not using parallax, just add stage normalmap instead of stage normalparallaxmap to your shader.

Is there a way to have glow/self illum textures in the rend2 shader?

[AshuraDX]

@@Xycaleth - @@DT85 just noticed that my spec texture did not contain the gloss map in alpha, aswell as the diffuse texture came without Transparency, saved my tgas wrong as I barely use them ^^U

here are the fixed textures https://www.dropbox.com/s/igttcwkp8we5mo9/overwrite.zip?dl=0

DT is a bit excited I see.

 

[Raz0r]

Do you mean an area light surface?
