| | | thx |
| This page is for:
| |
| | |
| *Tutorial/article requests.
| |
| *General material requests. Materials should be provided in a raw format, such as .vmf, so others can see how it was done. ''Be vague.'' General requests will be more helpful for the community.
| |
| *Questions towards the Valve team. This should keep their Talk pages clean, especially if the person to direct the question to may not be obvious.
| |
| *Answering questions posed here. Simply place the answer directly after the question, indented to be a clear difference. Further discussion should be kept to Talk pages to keep this page clear, if it does not clearly benefit the community.
| |
| *Posting requested materials. Upload them to your own webspace, and put the links here.
| |
| | |
| This page is '''not''' for:
| |
| | |
| *Editorializing. If you don't like someone's idea leave them alone.
| |
| *Mod recruiting. Create a page in the [[:Category:HL2 Third Party Mods|appropriate]] [[:Category:HL1 Third Party Mods|category]] and request help from there. Feel free to use the [[Template:Recruiting]] template. Check out an example [[Plastic Warfare|here]].
| |
| *Specific requests. Do not ask someone to create a player model for you, but you can ask for details about making your own.
| |
| | |
| This page will be split into more specific pages if it is needed.
| |
| | |
| ==Programming==
| |
| *A more in depth tutorial or sample of advanced material shaders would be nice. I am trying to implement dynamic lighting and dynamic environment reflections on an object, and am having some difficulty.
| |
| **Why are only 2 lights created in the common_vs_fxc.h file (cLightInfo[2]).
| |
| **Where do these lights get passed in (in the .cpp file?)?
| |
| **Can I have 5 render targets and render 5 passes of the world each frame (or at least to one view each frame, switching views each frame)?
| |
| **Can I manipulate the camera with my own transforms and remove the object (the one I want to have reflections) when I'm rendering the reflection render targets?
| |
| **Is there already functionality to do all or some of the features I'm trying to implement?
| |
| | |
| I'm already solid with the postprocessing effects pipeline, but the material shader system seems to function a bit differently. While I've been able to pass variables from the render to postprocessing shaders, I haven't been able to pass variables to material shaders. It would be really nice to have the TDD or some official docs for the shader system, but I know that's not possible, so if there is any way to answer some of these issues, I would greatly appreciate the help.

| Thanks!

| ==Level Design==
| |
| *A tutorial detailing the creation of the intro sequence of Half-Life 2, with specific focus placed upon the graphical effects used during the G-Man's speech (switching to black and white, warping the depth of field as you appear on the train, scenes from the citadel appearing overlayed on the G-Man's model, etc). I'm assuming these things are done with things already implemented in the code that can be summoned by the level designer at will. The source to this part of the intro level would also be a helpful addition to the SDK.
| |
| | |
| :: I thought the source to the intro level ''was'' included with the SDK. It's the first train station VMF, correct? --[[User:Campaignjunkie|Campaignjunkie]] 15:56, 31 Aug 2005 (PDT)

| | |
| :::Yes, and yes. --[[User:Charron|Charron]] 17:30, 31 Aug 2005 (PDT)
| |
| | |
| :::: Okay, the source is there. But a tutorial explaining how to set this kind of thing up would be nice. The .vmf is very complicated, using about a million entities, and it'd be much better to have the process broken down and explained in an article as opposed to trying to work out what each of the 50 logic_relay's do. --[[User:Graham|Graham]] 11:53, 2 Sep 2005 (PDT)

| :: This is a subject I know *very* well. I'll try to put something together. I wrote a quick bit on the script_intro entity a while back, but I've learned a bit since, and need to make a second pass at it to explain it more fully.

| * In HL2 savegames are named by their chapter title but there's no clear way to achieve the same thing for custom maps (their saves take the map filename). Anyone know? I'm pretty sure it's nothing to do with worldspawn. --[[user:TomEdwards|TomEdwards]] 03:21, 1 Sep 2005 (PDT)
| |
| | |
| :I think it's done in codes. When I changed gTitleComments[] content in gameinterface.cpp to make chapter unlocking work, I noticed the savegame name changed, too. CServerGameDLL::GetSaveComment names savefile. It compares map filename with gTitleComments[], and if the map is a part of a chapter, the chapter name will be used as savefile name. Otherwise the map filename is used. -[[User:N-neko|n-neko]] 17:46, 12 Dec 2005 (PST)

| |
| ** [[Turtle Rock]] used a model to create the waterfall on cs_militia. They simply created a plane, mapped a scrolling texture across it and then placed this plane atop of a normal water brush. The effect is superior to any brush-based alternative. I'll ask my modeling friend if we can do a tutorial on it, he did say it was ''laughably easy''. `[[User:Zozart|zozart]] <sup>.[[User talk:Zozart|chat]]</sup> @ 03:44, 21 Jan 2006 (PST)

| * Does anyone know if '''func_illusionary''' is cheaper for the engine to render than a '''func_detail'''? For example if you placed a detail where a player would never stray to.
| |
| :It would depend on the material used on them but in a fair fight func_detail should render cheaper. --[[User:Mark WiseCarver|wisemx]] 06:44, 20 Jan 2006 (PST)
| |
| ::To expand on this....func_illusionary is actually compiled into a map as a brush entity...while func_detail is compiled into a detail blob for the map...func_detail takes as much effort to render as world brushes do—'''[[User:Ts2do|ts2do]]''' 11:56, 20 Jan 2006 (PST)

How do I revert to the old window setup? I have tried everything, I even checked the "Load default window positions with maps" in the options menu. You would think that this would load the default window positions with maps, but it doesn't.

| [[image:NoChapterTitle.gif|thumb|No Chapter Title]]
| |
| *I am trying to figure out how to get the chapter title to appear when you start a new game for a mod I am making. I have gotten as far as getting the first chapter to appear in the new game dialog (no problem there), as well as getting a image to be displayed properly for the chapter (also easy) but I can't seem to figure out how to get the Chapter title to appear. All I get is #destiny_Chapter1_Title for a chapter title. (BTW: Destiny is the name of my mod.) See thumbnail image. It would really help if there was a clear easy tutorial that showed how to create new chapters for a mod and have the chapter title be displayed.

| * I am seeking a way of unlocking chapters in my mod but I do not know how. For example when playing HL2 you play a few maps thru the game and then when you goto the new game dialog and you see that chapter 2 has been unlocked and you can start a new game starting from chapter 2. How do we unlock chapters for our own mods? Do we do it in the maps using hammer or is there a script file or source code we need to edit? I have already provided a tutorial on how to [[Adding chapters to your mod|Add chapters to your mod]]. But the last thing I need to figure out is how to unlock chapters as the player plays thru the game.

| == HDR ==
| |
| | |
| It would useful to have more technical detail about the implementation of HDR, specifically the range of values and the way that the autoexposure controls work.
| |
| In its current version, the autoexposure seems to lower and raise contrast, varying the ''size'' of the displayed dynamic range, but keeping the shadow point constant, rather than keeping the size of the displayed range constant and sliding the whole thing up and down.
| |
| | |
| This means that while bright areas 'white-out', dark areas never 'black out' only become increasingly gray and low contrast. This implementation works well for HL2 style daylit areas but is very limited in usefulness for dark maps.
| |
| | |
| Also, it would be helpful to know if it is possible to control the speed at which the autoexposure adjusts to changes. At the moment it seems to adjust very quickly to darkening, but more slowly to brightening, which is the opposite of the human eye. I would be good if the tonemap_controller could also have parameters to allow level designers to control this kind of behavior, Like iris_speed_open and iris_speed_close for example.
