couldn't find a spawn point

yeah, also http://q3a.ath.cx/ warning me about it, so I replaced all CTF_xxxspawn with CTF_xxxplayer, it should work now in vanilla q3 as well
and now it's here http://q3a.ath.cx/map/xttower/

Hey everyone. I joined this forum pretty much so I could partake in the challenge. I love contests where resources are limited.

[obsidian]

Welcome, hope you stick around after the contest too.

Is there anything against making a separate botmap for generating a workable aas? (such as described by Simon here: http://www.simonoc.com/pages/design/mp/pom_bots.htm ) This would put me over the brush limit if the brushes used to make this aas map are counted.

The bots hate my map (or Q3 just hates my aas, whichever you prefer)

[cityy]

I reckon the custom texture rule applys for skyboxes as well?!

[Eraser]

I've built something that's got 15 brushes or so, and it's great that I still got 5 brushes to spare, but during construction it is alarming to see how tiny changes can end up in the brush count exploding. This is harder than I thought. It's a shame Q3 can't do concave brushes, that would make this so much easier

[obsidian]

Add 5 crates, DONE!

cityy: I think so, it's not too hard to create cloud layer shaders or other sky effects if a cube map is hard to do.

[Eraser]

If you're going for a space vibe, look up some PS tutorials for creating planets and stars. There's a bazillion of them and most of the time they are applicable in programs like GIMP or Paint.NET as well

caulk brushes count? cause i used one to fix vis problems and i exceeded the brush limit

[edit]
"Special invisible tool brushes (origin, trigger, hints, nodraw, clips, caulk, etc.) are free and does not add to the 20 brush limit."
somehow i miss that

[obsidian]

Nope, you're good. It's mentioned in the rules.

[fKd]

might scale it down a little, just play testing right now...

[cityy]

Good boy

[j3st3r]

Would a func_button made from the trigger texture count towards the final count?

[fKd]

It's simple, if ya can't see it it don't count...

[CZghost]

It's simple, if ya can't see it it don't count...

If it doesn't add tris to BSP tree, it doesn't count (like invisible may count, because this texture adds to BSP tree some tris with additive texture, the pure black color - invisible, but solid texture making tris, if you set r_showtris 1, then you'll see triangles on this invisible surface: it's normal visible texture, but you can see trough it, because it's pure black with blendfunc add).

I'm starting to fear that I won't be done in time for the deadline

Hi,
I need a bit of shader advice.
My island map (shown above) uses the same shaders as yadnar's shaderlab_1337 test map. There are a couple of issues I am not sure how to get round.
By placing the lightmap stage first I get perfect blending of the rocks into the pinky-orange skybox floor. But the trade off is I don't get the smoothing I get with the lightmap stage at the end of the script. Is there anyway around this? The second and perhaps most critical question is the shot above was taken with r_overbrightbits set to 0. When set to 1 my blended textures are bright like a lightbulb. How can I control this? Can I control overbrightbits via the shader or is there a blendFunc I should be using?
Am done with my map apart from this. I discovered the shader issue in fiinal testing.
Help appreciated

Early shot, I started looking into making some textures, haven't really come far though.

@donkey: Where can I find the shader you are talking about? :O

[dONKEY]

OK I semi-solved my problems, but could still do with some advice.
Apologies I should have posted the scripts before, but my little girl broke her arm yesterday and I have not had much time for this.
After playing about with various blends in the texture stages I have my shaders looking the same with overbrightbits on 0 or 1.
What I can't yet work out how to do is to enable phong shading with the lightmap stage where it is now.
I basically have four shaders.
This one is for unblended rock:

Code: Select all

textures/dk_q3w20b/g4_p
{
		qer_editorimage textures/dk_q3w20b/ed1.tga
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0
		surfaceparm nomarks

	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}

	{
		map textures/dk_q3w20b/g4.tga
		rgbGen identity

	}
	
}

This one is for the pink colour the rock blends into:

Code: Select all

textures/dk_q3w20b/pink_p
{
		qer_editorimage textures/dk_q3w20b/ed1.tga
		 
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0
		surfaceparm nomarks

	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}

	{
		map textures/dk_q3w20b/pinksky/20b_bk.tga
		rgbGen identityLighting
	}

}

rbg identityLighting tones down the blend just fine.

Then I have two blending scripts:

Code: Select all

textures/dk_q3w20b/g4tor2a
{
		qer_editorimage textures/dk_q3w20b/ed4.tga
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0
		surfaceparm nomarks

	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}

	{
		map textures/dk_q3w20b/g4.tga
		rgbGen identity
	}
	{
		map textures/dk_q3w20b/r2a.tga
		blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
		rgbGen identity
		alphaGen oneMinusVertex
	}
}

and

Code: Select all

textures/dk_q3w20b/r2btofog
{
		qer_editorimage textures/dk_q3w20b/ed6.tga
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0
		surfaceparm nomarks

	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}

	{
		map textures/dk_q3w20b/r2b.tga
		rgbGen identity
	}
	{
		map textures/dk_q3w20b/pinksky/20b_up.tga
		blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
		rgbGen identityLighting
		alphaGen oneMinusVertex
	}
}

Again in the second script rgbGen identityLighting darkens the blend when running overbrightbits.

My usual phong and blend shader looks like this:

Code: Select all

textures/dk_mymap/g1topath
{
		qer_editorimage textures/dk_mymap/ed_path.tga
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0

	{
		map textures/dk_mymap/g1.tga
		rgbGen identity
	}
	{
		map textures/dk_mymap/path.tga
		blendFunc GL_SRC_ALPHA GL_ONE_MINUS_SRC_ALPHA
		rgbGen identity
		alphaGen oneMinusVertex
	}
	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}
}

and my normal phong only shader like this:

Code: Select all

textures/dk_mymap/path_p
{
		qer_editorimage textures/dk_mymap/ed_path.tga
		q3map_nonplanar 
		q3map_shadeAngle 179
		q3map_lightmapSampleOffset 8.0
	{
		map textures/dk_mymap/path.tga
		rgbGen identity
	}
	{
		map $lightmap
		blendFunc GL_DST_COLOR GL_ZERO
		rgbGen identity
	}
}

Using my normal script, the rocks look fine but do not seamless blend into the bottom of the skybox. The set up at the beginning of this post achieves that but I have no smoothing and over bright washed out textures.

nice! digging the atmosphere.

[cityy]

@donkey: I know you fixed it already but the sky shader is made to be compiled with -gamma and -compensate; you could also lower the intensity value of q3map_sunext.

I'm almost done now; just gotta make a skybox and light it up. Though I'm out of quota @ cgtextures for today. :/

[Shrimp Scampie]

Still need to get the aas file to not stack overflow (and the bots to not be idiots) but that shouldn't be hard... (...final last words...)
