LOD Mixer Module for Kitserver 6 May 2,2020 ============================================================================= Version 6.8.0 1. SUPPORTED GAME VERSIONS -------------------------- PC: PES6 2. INTRODUCTION --------------- This tool was initially just for Level-of-Detail adjustment for player and goalkeeper models, but now has evolved into more general graphics/gameplay tweak tool. In addition to LOD, you can now turn on the crowd rendering on all cameras, and also do automatic aspect ratio correction, which is useful for widescreen modes. (PES6 does support high resolution widescreen modes, but doesn't use proper aspect ratio on them, so players look a bit fat. LOD Mixer allows to fix that). 3. THE IDEA OF LOD ------------------ This is by no means a formal definition of Level-of-Detail (LOD) idea, but merely a short introduction to the concept, which will hopefully be helpful in understanding what the LOD Mixer program does, and how to use it. Typically (and PES6 is no exception), a rendering engine in 3D games is designed to take advantage of the fact that objects that look small need simpler models than objects that look big. A close-up view of a car may require thousands of polygons to look convincing, but may only need a few hundred when the distance between it and the camera is big and the amount of pixels it occupies on the screen is small. By using simpler models for far-away objects, the game engine saves GPU cycles that could be used for creating additional visual effects, or just to maintaining a smooth frame rate. Level-Of-Detail algorithm is the logic that decides when to use a particular model for a particular object. For the task of rendering players and goalkeepers, PES6 uses 5 different levels of detail, which are dynamically switched depending on a set of factors: distance from camera to player, playing mode, active player, etc. #1: Very high-detail models, big (512x256) textures", #2: High-detail models, medium (256x128) textures", #3: Medium-detail models, medium (256x128) textures", #4: Low-detail models, small (128x64) textures", #5: Very low-detail models, small (128x64) textures", LOD #1 is used for cut-scenes and more in replays than in actual game. It's the only one that uses best quality kit textures - 512x256. LOD #2 and #3 are typically used for many cameras, including "Normal Long" and "Wide". LOD #2 is also used for some cut-scenes - like pre-match photos, for example, and also in replays. LOD #4 - on "Wide" and "Bird's Eye", and LOD #5 i was only able to see with "Bird's-Eye" cameras. To illustrate the concept, consider this scenario: The camera is really close to the player, so the game engine selects LOD #1 to show the very well detailed model of the player with nice-looking textures As the player moves away from the camera, at some point the game engine decides that the very high level of detail is not needed anymore, and it should be switched to next one - LOD #2, since the camera is now far enough and the user won't notice the difference. Here's where the problem occurs with PES6, PES5, WE9I, PES4 and WE8I: we actually DO see the difference, because KONAMI implemented a very aggressive LOD algorithm and it switches to lower-detail models way too early, and that's why we see annoying artifacts, as player balding and low-quality kit textures. I can only guess why they did it, and i think it's because the lowest denominator system - PS2 - couldn't sustain the smooth frame rate with a more concervative LOD switching algorithm. 4. HOW TO USE THE PROGRAM ------------------------- Run lodcfg.exe. The features are pretty much self-explanatory. Once you're satisfied with the configuration, press "Save" button. If you want to reset all the mods to original game logic - press "Defaults", and then "Save". Your configuration is saved into a binary config file - lodmixer.dat. Next time you run the game, the Kitserver will load this configuration. 4.1. LOD LEVELS --------------- If you running the program the very first time, you'll see the default LOD configuration: 1,2,3,4,5. This means that the LOD algorithm will use #1-models for LOD #1, #2-models for LOD #2, and so on. Change that configuration by selecting different items in drop-down boxes, press "Save" button, and that's it. You can now close the LOD Mixer and start the game. The idea of changing the default setup, is to force the game engine to use higher-detail models for the cases when it used simpler ones, and vice versa. For example, you can force it to use best-detail models for LOD #1,2,3 and keeping the defaults for LOD#4 and 5. This is the configuration for such example: 1,1,1,4,5. Or you can choose 5,5,5,5,5 which will result in really simplified models used for all cases. (This extreme config looks kinda funny :-), if for instance your PC is not powerful and you want to sacrifice some visual quality for smooth frame rate. Typically though, if you have a good PC, you'd want to use something like 1,1,1,2,2. Now, for all of you, who have honestly read the above sections and has difficulty understanding the concept, don't be discouraged. LOD Mixer is a very simple program: you can use in a purely "black-box" experimental way: select a random configuration, press "Save" button, close the LOD Mixer, start the game and see how your changes affect the display. You can also try 1,1,1,1,1 if you have a powerful computer. That's as much detail/texture as you can do with PES6. For me the following configuration works quite well: 1,1,1,2,2 (Which means that the five drop-downs look like this: LOD #1 - 1: Very high-detail models, big (512x256) textures", LOD #2 - 1: Very high-detail models, big (512x256) textures", LOD #3 - 1: Very high-detail models, big (512x256) textures", LOD #4 - 2: High-detail models, medium (256x128) textures", LOD #5 - 2: High-detail models, medium (256x128) textures", Numbers on shorts (and - for national teams - on players chests) are always there, no more "fake" baldness, captain armbands are always visible, cut-scenes (pre-match photos and etc.) have the highest quality. On my PC, i didn't experience any slowdown with this configuration, but you'll have to try it on yours to see how it deals with the task of rendering more polygons. In a way this is a fun experiment, which gives you an opportunity to affect the game engine. 4.2. CROWD SWITCH ----------------- Yes, you can now see the crowd on all the cameras! PES6 rendering engine disables animated crowd display on several cameras: Normal Medium/Long, Wide, Bird's-Eye, Vertical Medium/Long. It uses a flat crowd texture, which doesn't look quite convincing. (Better than PES5/WE9 which had no crowd at all, but still rather bad looking). Normal Long and Wide are probably the two most popular cameras, and without the crowd, the match athmosphere is lost. By setting the "Show crowd on all cameras" checkbox, you can fix that problem. Just check the checkbox, and hit the "Save" button. Not much more to say here. :) 4.3. ASPECT RATIO CORRECTION ---------------------------- Playing the game on a widescreen LCD montor on a high resolution (such as 1680x1050 or 1920x1200) is wonderful, but it also reveals the problem of aspect ratio. The game engine still uses 4:3 aspect ratio, which results in stretching on a widescreen. Everything is slightly squashed: players become a little bit fat, and the ball is not round anymore. Set the "aspect ratio correction" checkbox, and the LOD mixer will expand the viewing area horizontally to adjust the aspect ratio to proper value, calculated as vertical-resolution-in-pixels diveded by horizontal-resolution in pixels. So players and the ball look good again, and also you get to see more of the field! After all, that's what the widescreens are for :) New in 6.8.0 is "Manual Aspect Ratio" setting. Here, you can set the exact aspect ratio as you want. Sometimes, this is useful, because the pixel on your screen may not be exactly square, or maybe you wish to have your players slightly more "compressed" for that retro-look :-) . Automatic mode calculates aspect ratio as width-of-screen divided by height-of-screen. So you can start with that value and tweak it as you see fit. Examples: ~~~~~~~~~ For exact 16:9 screen, you would need to put: 1.77778 For exact 16:10, it would be: 1.6 5. CREDITS ---------- Game algorithms analysis and programming by juce.
