rd-rend2 (old thread)

[Tempust85]

Yeah it is broken. I'll have a browse in the code to see if I can find the area where it does specular.

 

About that parallax thing, the normal map itself could be too strong. I suggest playing around with the levels.

[Boothand]

Making the normal map hardly visible removes the issue, but at the same removes the effect of having a normal map. As long as it has an effect, it causes the above posted to happen.

 

Here's another issue. A texture with a normalparallax map makes a sudden sharp transition. It feels a bit in the same category.

 

 

 

 

 

 

 

[Tempust85]

Ok, put the normal map back how you had it originally and invert the green channel of your normal map. I can't test this myself as the parallax image isn't showing up in this thread anymore.

[Boothand]

Haha, yeah it's the normal map then. I just wonder if this would only happen in rend2, or if my normal map is generally not good. I've had quite many approaches to making this normal map. Ended up just generating it in Crazybump.

 

Inverted green channel:

 

 

 

 

 

 

PS. The parallax image is back, my bad

 

And if you wanted to test it yourself, here's the diffuse.

[Xycaleth]

Try turning off texture compression? Should be an option in the regular video menu.

[Boothand]

Hmm which option would that be? Didn't find the cvar either.

 

 

 

 

 

 

 

PS. It happens with other textures too. Check the wooden wall: https://dl.dropboxusercontent.com/u/58757568/normalshadewoodenwall.jpg

[Tempust85]

The parallax texture is now showing up in the thread, i'll muck around with this tomorrow and see what if I can't find what's going on.

[Raz0r]

Hmm which option would that be? Didn't find the cvar either.

Could be r_ext_compress_textures 0. It requires a vid_restart

[Boothand]

That doesn't seem to be what's causing it. It was already on 0, the default.

This is what I get with your normal map + parallax + white diffuse + r_forcesun 1:

 

 

I had to modify your shader a bit:

textures/bricks/bricks3
{ 
	qer_editorimage textures/bricks/bricks3 
	{  
		map textures/bricks/bricks3
		rgbGen vertexLit 
	} 
	{  
		stage normalparallaxmap  
		map textures/bricks/bricks3_nmap 
	}
}

Don't fall Kyle, that glass might break

[Tempust85]

That kyle is a normal map test which I painted an X on his back, ignore it.

 

I had a good muck around and rend2's specular is broken. The problem doesn't lie with an incorrect shader, because that exact shader shows specular in ioquake3 rend2.

[Archangel35757]

So are normal maps for characters fully implemented now using rend2?

[Boothand]

Hmm what sun elevation did you use? I'm still having the issue using vertexLit. It seems to be on that general area. Doesn't happen on one other of my walls, which is a bigger surface. And thanks a million for the r_forcesun 1 command! It made rend2 about 10 times more rewarding for me  Only wish it worked on surfacelights as well.

[Tempust85]

The sky I used is hevil (base JKA shader), using r_forcesun 1 (r_forcesun 2 is a moving light source).

 

r_forcesun should only be used for testing, you should always make a proper rend2 compatible sky shader.

 

@@Archangel35757

 

I think so. Won't really know for sure if it's 100% working until someone like @@Almightygir puts a model ingame. My test subjects suck because they are either really basic or are model ports.

[Boothand]

Hmm. Forcesun 2 is very impressive, although it crashes with the lightmap. Also, was that compile done with -light? I think the issue only arises with the lightmap.

 

But will a *proper rend2 compatible shader* do the same magic as r_forcesun 1? It doesn't seem to affect FPS that much. It adds a lot of nice detail to my map..!

[Xycaleth]

The force sun stuff is mainly for debugging purposes. There's a way to do the same thing using sky lights but I can't remember how.

[Tempust85]

@@Boothand

 

It will do the same thing, yes.

 

I compiled my test map with -light. Here's my other test map sky shader which is rend2 ready:

textures/skies/testsky

	qer_editorimage textures/skies/sky.tga

You don't need q3map_sun(Ext) and q3gl2_sun, one of them (hopefully the latter) will be used always.  And trying to plug said shader itself into vanilla will break on q3gl2_sun and q3gl2_tonemap anyway.

[eezstreet]

Not quite, since vanilla doesn't load .mtr files.

[ensiform]

Exactly.

[Tempust85]

SunExt is the vanilla renderer sun IF you plan on having both renderer compatibility. It also only works if it's a .shader. Having gl2_sun & tone map doesn't break anything in vanilla on all of my tests.

 

Rend2 manual mentions this, have a look.

[ensiform]

The vanilla renderer never actually checked it before OpenJK.  It only looks for the first 6 numbers anyway.  The extra information to ext is only for q3map2.

 

You missed the point, though DT85, you wouldn't use BOTH in the .mtr file as vanilla can't load it.

[Tempust85]

That's right, which is why I said it would only work if you used a .shader.

[Tempust85]

I'll just drop this Ghoul2 Maul head right here:

 

 

Diffuse Map + Normal Map + Specular Map + specularReflectance & specularExponent in the shader.
