Installation.

Download the shaders and OGE plugin from the links above. In the plugin archive, the DepthTest.dll goes in your "data/obse/plugins" folder. The shaders, both in the plugin archive and the ones you download seperately, go in your "data/shaders" folder.

The next step is to open up the "shaderlist.txt" in your "data/shaders" folder. Remove its contents, as these are example plugins that do not produce playable effects. Then add the names of the shader files you have installed and wish to see the effects of into the file. Make sure to spell them exactly, and include the .fx extension. There is a specific order required for the file names added, as listed below.

To see the effects in game, you must open up your console and enter "ShowTestShader". To disable the effects, again open the console, but this time enter "ShowTestShader 0".

Proper shader load order.

As pertaining to MGE, this should be the order of your shader list with the current release of shaders.

-SSAO
-DepthOfField
-Godrays
-Edge detection shader
-Any other shaders available

*FAQ*

*Is this a RELz? Should I download this?
OGE, like MGE, will be a growing project with many new applications added on with each feature. So far we only have a few test plugins and shaders but we encourage all to try them out.

*Does this require OBSE? If so any specific version?
Yes it does require OBSE. As for the version, currently we are not sure. Best to just keep the http://obse.silverlock.org/beta/obse_0018_beta_6.zip.

*Does OGE require any specific hardware to run?
The shaders are compatible with both ATI and NVIDIA graphics cards, although both the Godrays and Depth Of Field shaders require a Shader Model 3 compliant graphics card to run. Any NVIDIA graphics card that is GeForce 6 Series (released 2004) or newer supports Shader Model 3.0. Any ATI graphics card that is Radeon X1000 Series (released 2005) or newer supports Shader Model 3.0.

*Can I add to this project?
Yes feel free to add as many things as you want.

Creating shader effects requires knowledge of programming in HLSL or ASM, while helping Scanti with the OBSE plugin requires knowledge of C, DirectX core functionality and the OBSE plugin system. For those who are not programming-capable, contribution is more limited, though we welcome support and whatever else you can bring to the project. Especially cake or ice cream.

*I found a bug...
Good for you. If you find a bug, please list the error in-detail here. We can help you more when you explain the problem better

*My Godrays is just a searchlight in clear weather.
First off, Godrays is best displayed on cloudy weather types, in the morning from 6 to 8am and 7 to 9pm. But if you get the searchlight effect, you have to edit the shader FOV for Godrays to match your ingame FOV for oblivion. Example would be if your playing Oblivion on a 95 FOV, you have to edit your Godrays to a 95 FOV. The shader line should be "DefineFOV" near the top of the code.

*Which version of OGE do I use?
So far, any version is confirmed to work. We haven't really fully tested them yet but its safe to just use Scanti's updates (as they are needed to run shaders.)

*How do I reduce over bright kill and whiteout in the sky when I stare at the sun with Godrays Enabled?
Use http://dl.dropbox.com/u/519253/NoGlare.7z texture fix for sunglare and disable HDR. You can optionally enable bloom to keep some white effect and brightness of the sun.

*Why do objects in the distant have weird black stuff on them when fog weather is active?
That is from the test SSAO. The author stated that it had some fog bugs. Until it's fixed, they will be there.

*I get blue light rays during the day time.
Go in the godray.fx file and reduced the "static const float saturate = 0.540f;" from 540 to 040, this will decrease the saturation values to prevent your screen from turning blue.

*Once I got Godrays to work, my AA disappeared? WHY?!?
The method used to expose the information used to create the shader effects is incompatible with Anti-Aliasing. This is reported to be the case on both ATI and NVIDIA graphics cards. No confirmed solution is available at this time.

*My screen is all blue?
Blue Screening can result from a number of problems, mostly with related to your graphics card. Make sure you atleast have a PS 3.0 graphics card and have the required DirectX in the OP download. Also make sure you spelled each and every shader named EXACTLY as they should be spelled, adding the (.fx) as well.

*SSAO demolishes my FPS; any ideas?
http://www.gamesas.com/bgsforums/index.php?showtopic=1060479&st=160&p=15476196&#entry15476196 provided by BDBB is worth a shot, it's helped quite a few people.

*What is the most recent version of this project?
As of sunday, 01/09/10 at 11:17 PM, Scanti's Latest Test http://dl.dropbox.com/u/519253/OBGEv2.dll - USE AT YOUR OWN RISK.
"Showtestshader" command is not fully implemented. To load shaders, simply use the LoadShader "" command in the console menu. (also allows for use of selective shaders, instead of all at once)

This project is in a Test Alpha Phase. Expect bugs when using newly created shaders, or when using/tweaking the shaders on your own.

Introduction has stayed constant, with some minor edits by myself; last posted by http://www.gamesas.com/bgsforums/index.php?showuser=334151.

Thank you Snow_EP for opening a new thread :foodndrink:

Cheers for the new thread. Could the red font colour be changed for something a bit more readable though?

Regarding current state of OGE/DepthTest/OBGEv2: (excerpt from a discussion, quotes are ABO and myself)




For easier recall.

Hey guys

Fantastic work here everyone! Im loving the extended graphics! =P

Currently I have Godrays working great, although sometimes it seems when I see them through trees, the rays seem pixilated or something? If someone doesnt understand, Ill post a screenshot.

I love the effect of SSAO, but It DESTROYS my fps. Ive tried setting the samples to 1 and the area to 9.2 like that, but it didnt really help that much... Any other suggestions? I'll keep playing with it... I can get system specs if needed.

Done and done; the OP is also edited for more streamlined use. And if you could please attempt to implement that clouds shader, it would be wonderful, I don't really care if they don't line up with the clouds in the sky.

Unfortunately the SSAO shader is not the most optimized; and seeing as you've already applied the fix, you've basically done all you can do. At this I'd simply wait for a newer, more well optimized release.

sigh... okay thanks for the help...
:stare:
waits
:stare:

Glad I was able to help with that second post by being the one who needed correcting.

Request.

More shaders appearing and I think it would be keen if next to the download link of each there is a short description of what they do and maybe two screenshots (1st and 3rd person) that illustrates shader.

thanks for considering.

I think we should post only screens of a unmodded Oblivion, that only shows all the shaders at work. It would give new people a better idea of how stuff looks and works compared to a vanilla oblivion.

Before/after would be better.

In regards to the SSAO shader, I also had the fps issue so I dropped the samples to 1 and increased the area to 9.2, which worked great. Then i decide to mess around a bit, and I found that it didn't matter what I set the area size to. So i get the same effect with samples at 1 and area at the default 1.7. I didn't lose/gain any fps with the different areas either. idk if anyone else wants to try to see what the result is.

What is the Crysis Color Mood Shader all about? Any screenshots of that floating around?

How about we create a Nexus page for this? I've been thinking of it for a while, but since we've got a fair number of shaders on offer now, and a ton of screenshots, we can upload them all there, and have a central storage place for everything. Then, once the project gets organised, we can use it as the project page too, for downloading Scanti's stuff as well. For the moment though, I'm thinking just shaders and screenshots.

If we give all the shader writing people editing access, then they can update their shaders and related info on them as they want, no hassle.

I think thats a good ide wrinklyninja, beacuse I believe that many modders on tesnexus doesn't stop by bethesda forums very often :thumbsup:

Well, I think that's a bit premature seeing that all of these shaders are run using various dev./alpha builds of the actual plugin. It would be better to wait until we see a beta release from scanti before we go about on actively spreading the word around.

I've uploaded a new version of the edge detection shader (same link) that includes the edgeAA feature. Screenshots can be found in this http://s659.photobucket.com/albums/uu320/shademe/shader%20stuff/ (the newest 4 that look Oblivion-esque). It uses the blur code from the DoF shader, taps and all - I hope wrinklyninja doesn't mind.

Mood Color Difference -> http://i659.photobucket.com/albums/uu320/shademe/shader%20stuff/c1.jpg \ http://i659.photobucket.com/albums/uu320/shademe/shader%20stuff/c2.jpg | http://i659.photobucket.com/albums/uu320/shademe/shader%20stuff/c3.jpg \ http://i659.photobucket.com/albums/uu320/shademe/shader%20stuff/c4.jpg . The best usage scenario would be to write a mod using OGE's script functions to use the shader to dynamically change the filter color at runtime, depending upon environ, weather and suchlike.

PS : The OP calls the OGE source repository a "dump". While not far from the truth, I suggest that it be changed to clarify.

I wasn't meaning as a release, or to spread the word - it's just getting near the point where we'll have a lot of stuff spread all over the place, and it will get very messy, and harder to organise later. I'm sure if we put enough discouraging warnings, as well as notes saying there will be no support for any problems people encounter, then few people will download it thinking it's ok to use, without knowing what they're doing.

And feel free to use the blur. I'm pretty sure I ripped the blur weights off the SSAO shader myself.

A mod called (ScreenEffects v1.0) gives full in game colour adjustment options and it was even used in a weather mod called (All Natural) in the (Enhanced Seasons with ScreenEffects v1.0 Support). It is removed currently but it is planned to be rebuild.

ScreenEffects was good for simple effects control, and a handy way for the average modder to tap into shader effects. it's not a solution for what we're looking to do though, which is above and beyond it's scope. SE is basically what prompted me to learn shader programming, but once you know that, SE becomes unneeded, as it's middleware, but you can bypass it.

And I don't think SE is actually used in anything anymore. I'm pretty sure the only mods that used it were the Enhanced Seasons feature in EW and AN, and Ambient Dungeons. I rewrote both to directly apply shaders though.

I see. I'll inclined to agree with you about the organization bit though - The thread does tend to get cluttered. A Nexus page should look more presentable and easier to manage.


I know of it. The photo filter I posted can be seen as a slightly more refined version of SE's color manipulation feature. It should produce a more desirable effect than the latter's.

I really hope The (ScreenEffects v1.0) Mod will still be supported by the new OBGE.DDL versions. It is a really nice tool to manually adjust the in game visual settings. For as well game play as making really nice looking screenshots.

Scanti, are you any closer to finding the surface normals ? :angel:

@ Sjors Boomscors: If you look at the 2nd post, you'll see that the testing I did showed that mods made with OBGE (Timeslip) worked perfectly well with OBGEv2. This should also apply to ScreenEffects, though I haven't tested it.

If someone could remake ScreenEffects to work with OBGEv2 that would be optimal I think. For the "average" modder who can't write shaders themselves it is a pretty useful tool. The only reason that I haven't yet started to use ScreenEffects for my mod is that there is the possibility of a new version coming out for this. You said yourself that the SE shaders are simlpe and easy to write, so including them in OBGEv2 shouldn't be too hard right? Pwease?

Great work guys by the way!

What the ninja said in his last post. The mod itself won't be updated in the foreseeable future, as its author has basically left the modding scene. And to my knowledge, there isn't another working on an update for it.

I talked to him(qzilla) some time ago and got the rights to use his shader for Morrowind. But as stated, earlier version of OBGE is working with new OGE/OBGE perfectly. And the shader will work with only OGE too separately. The control from an ingame gui is another modder's job at the end, and I am sure those kind of functunality will be in new OGE's future. So there is absolutely no problem or conflicts to get screeneffects shader to work with new versions of OGE. In fact right now it should work right out of the box. Copy the fx file and load it, it will work, customization is similar with godrays shader.
