I'd rather a fully functional rend2 before adding other stuff in. There's still issues with ghoul2 models amongst other things. I wouldn't expect it anytime soon.

What are the current list of issues (Ghoul2, etc.)?

I'm a long way off adding anything new at the moment. I want to get the performance up to an acceptable level before adding new features.

So do you have any issues list? (Ghoul2 issues, etc.) Perhaps some of the experienced coders could help you knock some of them out (@smiletheory, @@redsaurus, @@eezstreet, @@ensiform)?

Messing around with varying the specular and gloss values! The black spheres have maximum gloss and specular - they should be full mirrors but they're not for some reason so I'm debugging that. Going left, the specular is decreasing so you see the specular lobe expand out until it's no longer visible. Going away from the camera, the gloss is increasing, so reflections should become clearer (but cubemaps aren't working :()

Does…

Cube Map = Environment Map

 

???

 

Reverse the effects so that the ball closest to camera shows the Max Gloss & Spec (...and thus player and environment reflections).

Cubemapping in ioquake3 rend2:

Dedicated a whole wall to the cubemapping. There is also a hint of cubemapping on the floor. It works with the normal/parallax map so it looks nice.

 

And here's the exact same map (shaders, textures, etc) in openjk rend2:

Found the problem with cubemaps, so I can show what the map should look like :)

 

This shows what kind of effect you get with differing specularity and glossiness.

And then a close up from max gloss/reflectance, with glossiness decreasing as you go from left to right.

There's a lot to be said about this which I'll try and post later, but for now here's some pretty pictures :P

 

BONUS SCREENSHOT! So the only thing I've changed in this screenshot is the sky shader. I've not recompiled the map

And for those curious, all the spheres have shaders that look like this:

 

models/map_objects/rend2/sphere_100_100
{
  {
    map $whiteimage
    rgbGen lightingDiffuse
    specularReflectance 1.0
    gloss 1.0
  }
}

Nice, I'll update the code tomorrow and give it a whirl with my map. Imagine cube mapping on my ep7 trooper armor....only a hint though but damn, that with normal maps...holy shit lol.

 

Also, what do you think could be wrong with rend2 making my map a lot darker and have next to no specular compared to ioq3?

r_overbrightBits and r_mapOverbrightBits are different between Q3/JA, r_intensity can compensate sometimes.

I think ioq3 rend2 has a gamma correction option too, somewhere.

 

Perhaps if it's using sun shadows etc?

It could also be something I've changed in the specular code. I've removed the different specular algorithms and am settling on only one. I think r_specularMapping 3 in ioq3 corresponds to the specular mapping used in our rend2.

 

Btw, here's the test map that I used in the screenshot:

I intend to update this test map and make new test maps as a learning resource.

So this is what I can manage to do for Kyle's saber with my poor programmer art. Left is my re-shadered version and retextured version, right is vanilla shader.

If you're interested in trying it out, here's the latest rend2 DLL:

https://dl.dropboxusercontent.com/u/874909/rd-rend2_x86.zip

 

Make sure to grab latest OpenJK version as well:

http://builds.openjk.org

 

And also here's the test map I'm using (minus the sabers):

Is that new shadow?

The lighting will look better in rend2 because it's calculated on a per pixel basis instead of a per vertex basis as in the default renderer. The point of the screenshot was to show I had fixed a bug where some triangles on Luke's face weren't drawn properly!

 

@@AshuraDX if you could do that I'd very much appreciate it! Thanks :)
