Bloom in Saint Lucia

Dram · October 27, 2008

Not sure if anyone knows this, but bloom already exists in the SL build (off by default).

Do note that it can be quite taxing on performance, depending on settings.

EDIT: Apparently some files required for bloom were not included in the release, causing a black screen if bloom was turned on. If this is the case for you, then download this pk4 and place it in your doom3/saintlucia/ folder. It contains the two material files required for bloom to function correctly.

http://72.8.59.188/TheDarkMod/files/TDMBloom.pk4

Here are 4 variations of settings I use - low to ultra:

LOW:

r_bloom = 1

r_bloom_contrast_min = 0.6

r_bloom_contrast_mult = 1

r_bloom_buffer = 3

r_bloom_blur_mult = 0.9

MEDIUM:

r_bloom = 1

r_bloom_contrast_min = 0.75

r_bloom_contrast_mult = 1.15

r_bloom_buffer = 4

r_bloom_blur_mult = 1.05

HIGH: (Best IMO)

r_bloom = 1

r_bloom_contrast_min = 0.9

r_bloom_contrast_mult = 1.3

r_bloom_buffer = 5

r_bloom_blur_mult = 1.2

ULTRA:

r_bloom = 1

r_bloom_contrast_min = 1.3

r_bloom_contrast_mult = 2

r_bloom_buffer = 6

r_bloom_blur_mult = 1.5

The also an extra bloom control for turning on or off blooming of the HUD (off by default):

r_bloom_hud = 1

Different Settings for Bloom

Also, there is another wonderful little shader effect which you can turn on, making the game look like a noir cartoon (quite awesome actually. Again, off by default):

g_rotoscope = 1

This effect's performance impact is negligible, as no FPS drop could be seen.

Rotoscope Compare shot 1

Rotoscope Compare shot 2

Dram · October 27, 2008

Added screenies...

Please note these wonderful effect shaders were donated to us by:

Hellborg - For his Rotoscope (Noir cartoon-like) shader

maha_x - For his bloom shader and source

Just thought they deserved a mention

Also it is possible to use either of these shaders in in-game cutscenes via map script. You would do this by executing the following script command within a function in your map script:

sys.setcvar( "g_rotoscope", 1 );

So if you wanted to (for example) have the map start off with the rotoscope shader you would just add that command to the void main() function in the map script. For example if we wanted this in Saint Lucia:

Change this in the map script in the .PK4 from:

void main()
{
	// key starts out hidden so that we can grab the cap before frobbing it
	$room2_key.hide();

	m_hatkey_hat_frobbed = 0;
}

To:

void main()
{
	sys.setcvar( "g_rotoscope", 1 );
	// key starts out hidden so that we can grab the cap before frobbing it
	$room2_key.hide();

	m_hatkey_hat_frobbed = 0;
}

This would mean that Saint Lucia would start out with the rotoscope shader on. You should not forget to set this to off however in a later function, or else it will stay on for the next map etc and the player would have to turn it off himself via console.

Hope that leads to some awesome cutscenes

AluminumHaste · October 27, 2008

Awesome thanks man, I knew about this stuff but never really bothered, I might just turn bloom on from now on.

Dram · October 27, 2008

No probs, I posted this because I noticed that in an interview with OMGPCGames.com he asked whether we were planning on implementing bloom or not, and it has been in TDM for quite some time now. I believe even in Thief's Den - same settings.

The interview I'm talking about is here.

STiFU · October 27, 2008

I asked about the bloom in another thread too, because I am having a problem with it. When I enable it the screen turns black. The console says that textures are missing e.g. blurx1024, blury512. I patched Doom 3 to 1.3.1 number 1304. So everything should be fine. How come the textures are missing on my installation?

Dram · October 27, 2008

Hmm, please check this:

Go into your saintlucia/ folder and find the materials/ folder, then check if within it there is a file named tdm_bloom.mtr

If it is not there, then copy an existing .mtr file, rename it to tdm_bloom.mtr. Then, open it, erase its content and paste the following into it:

Then save it, and try bloom again. If that fails, then there must be another problem. What vid card do you have btw, and what operating system are you using?

Dram · October 27, 2008

Thinking about it more, could be that you are missing the shader files themselves. Check your saintlucia/glprogs/ folder and look if you have the following files:

blurx.vfp

blury.vfp

blurx0064.vfp

...etc up to...

blury1024.vfp

If not, then let me know and I will package them up into a pk4 that you can plop into your saintlucia/ folder.

STiFU · October 27, 2008

Still a black screen, but at least he finds those two textures I mentioned earlier. My Pc is still not finding the following files in the textures/afx folder: afxweight, afxmodulate, afxadd . I am running WinXP SP2 with a Geforce 8800 GTS here. I also had Bloom running on my previous install of doom 3 and in thief's den (I think).

I just tried to enable it in base-doom3 and was pretty suprised to find out, that the command r_bloom didn't exist. I am going to download the patch your linking to and check out if the patch I had on my hdd is somehow corrupted.

Bloom was a community addon, not a default doom 3 setting.

Yeah, as NH said, it was a community addon which the developer allowed us to use.

As for those missing files, check your materials folder again, and look for tdm_bloom_afx.mtr. If you do not have it, again create a text file etc and paste this into it:

//################ Maha_x's materials ##########################
//	Modified by Clone JCDenton to work with Use_less bloom 
//########################################

textures/AFX/AFXweight 
{

{	
	vertexProgram 	afxweight.vfp
	fragmentProgram	afxweight.vfp

	fragmentMap 0 _currentRender
	fragmentMap 1 _afxweight
}
}

textures/AFX/AFXmodulate
{
noshadows
noimpact
sort	postProcess
{	
	rgba 1
	vertexProgram 	afxmodulate.vfp
	vertexParm		0 parm0
	vertexParm		1 parm1
	fragmentProgram	afxmodulate.vfp

	fragmentMap 0 _fsfx_input
	fragmentMap 1 _afxweight
}
}

textures/AFX/AFXmodulate2
{
noshadows
noimpact
sort	postProcess
{	
	rgba 1
	vertexProgram 	afxmodulate2.vfp
	fragmentProgram	afxmodulate2.vfp

	fragmentMap 0 _fsfx_input
	fragmentMap 1 _afxweight
}
}

textures/AFX/AFXadd
{
noshadows
noimpact
sort	postProcess

{	
	rgba 1
	vertexProgram 	afxadd.vfp
	vertexParm		0 parm0
	vertexParm		1 parm1
	fragmentProgram	afxadd.vfp

	fragmentMap 0 _currentRender 
	fragmentMap 1 _fsfx_input
}

}

Hopefully that should make it work. Again, if it doesn't then check your glprogs folder and look for these files:

afxadd.vfp

afxblend2.vfp

afxblend.vfp

afxmodulate.vfp

afxweight.vfp

STiFU · October 27, 2008

Oh yeah, sorry, I am a little out of it today, but now I remember. It was a feature of the Maximum Graphic Mod. (Which looks astonishing by the way)

The .vfp files are in place and the patch was correct too. I assume there's another .mtr file missing which defines the afx shaders.

Edit: Darn, why do I always see your posts too late... The other .mtr files didn't exist indeed and it works now. I guess you should provide a seperate download for these files or alter the SaintLucia.exe . r_bloom was actually the first thing I tried, when launching the demo.

Thanks for your help!

hehe

In any case, should work now. Let me know the results

Dram · October 27, 2008

Cheers for the heads up STiFU, I've updated the main post with a download-able pk4 for bloom to work.

STiFU · October 27, 2008

I have just been playing around with the bloom settings a little to find a setup suited for my sophisticated eyes. :laugh: I found that lowering the r_gamma setting and raising the r_bloom_src_mult instead results in a better/different contrast. (I used values of 1 and 1.7) This of course is just a question of taste. The world is rendered a little bit more fable-like with this adjustment, but I think it really fits into the overall atmosphere.

**Springheel** · October 27, 2008

The world is rendered a little bit more fable-like with this adjustment, but I think it really fits into the overall atmosphere.

That's exactly why we don't officially support it...the TDM universe is supposed to be (and look) gritty and realistic. But as you say, personal taste.

Hi new guy here.

Now I'm having a problem with the bloom effect, anytime i enable it the game becomes upside down like i'm walking on my head. :z

I have a ATI 3870 card and i did everything Dram said. Please help.

Weird, could you post a screenshot please? Also, when it is upside down, is it perfectly sharp, or is the bloom being applied? It'll help narrow it down with a screenie.

Here is the screenshot, i hope you find what is the problem.

That's..........fucked up yet cool at the same time, sorry that's all I can say at the moment, I really have no idea.

**Springheel** · October 29, 2008

I saw that problem once upon a time on D3W, but I can't remember what caused it. It's a D3 issue, though, not specifically a TDM one.

Dram · October 29, 2008

That is truly strange. It seems it is flipping the render image of the world and applying the blurred bloom image correctly.

BTW, did you create the two material files or did you just download the pk4 I posted above?

HMart · October 30, 2008

I downloaded the pk4 and created manually all the files that you said if missing to create.

STiFU · October 30, 2008

Well the files are actually in the pk4, so you didn't need to create them manually again. But that still shouldn't cause the problem...

HMart · October 30, 2008

But that still shouldn't cause the problem...

Yes, i deleted the PK4 and the problem still remains. But one thing is certain, the bloom shader is causing this so something on it is making the engine go crazy on my end.

Can it be GPU driver related? I'm using the new 8.10 ones.

Dram · November 1, 2008

Hmm, one thing you can try is switch to older drivers and see if it happens there, otherwise, I don't really know what could be going wrong, so it must be driver incompatibility.
