    A Simple Guide to Texture Modding

    A Simple Guide to Texture Modding (yes please I want to write number on my Daring's stern) Source: PunishedKAsual Royal Navy Destroyer Pennant Number & Funnel Bands Mod by [KA]sual Itasha (痛車) but for ships. Image courtesy: @Compass_Rose, a eminent modder from NA server who does a ton of anime-themed modding. Be sure to check out his works at the Visual Mod section on the forum! Foreword Do you want to put your anime waifu onto the side of the ship? Interested in adding hull numbers to your Cruiser? Wanna change the wooden deck to a metallic one? Texture modding allows you to modify the exterior appearances to your liking. This guide serves as a exposition and introductory manual to the world of texture modding The actual Guide starts here... Tools you will need 1. Wows Unpacker A tool released by Wargaming. You need it to extract relevant files from the WoWs Game Client. You can acquire the software and a guide here https://forum.worldofwarships.eu/topic/113847-all-wows-unpack-tool-unpack-game-client-resources/ 2. Image manipulation program (Paint.NET/ GIMP / Photoshop) A image manipulation software such as Paint.NET, GIMP and Photoshop is needed to edit .dds texture files. Paint.NET is a lightweight freeware. While the software is capable for simple edits, on more complex edits, one will quickly find the Paint.NET ‘s functionality on the rudimentary side, limiting the potential of what you can do. GIMP is a open source software counterpart to Photoshop. To open and edit dds file you will want to download a DDS plugin for GIMP. [Edit: There are reported compatibility issue with DDS file generated with GIMP, you are recommended to compile the final dds files with Paint.NET should you wish to edit with GIMP] Photoshop(+ Nvidia dds plugin). Software of my choice. The creative suite boast an all-rounded creation tool and UI optimized for. However, the software will incur licensing fees. 3. Wows Client Obviously. 4. Patience, Perseverance and Love (very important!) Modding is quite a timeconsuming and can be frustrating at time. Keep up your love on your shipfu to make amazing mods! Extracting Files Open the wows unpack tool A ship texture files are stored in the /res/content/gameplay/ with a logical file structure. Simply natvigate. For example, textures files for USS Battleship Iowa are located in res/content/gameplay/ship/battleship/textures/ and files for German Destroyer Z39 would reside in res/content\gameplay\germany\ship\destroyer\textures . Similarly, turrets, torp tubes, radar arrays are all packed in a similar file structure. For every ship in the game, there would be a set of 4 basic texture files that ends in _a.dds, _o.dds, _mg.dds, n.dds. Larger ships will involve multiple sets of texture files for their Hull(hull_a.dds), Superstructure (deckhouse_a.dds) and Torpedo Bulges(bulge_a.dds). Each of the files serves an unique propose in the appearance of the ship, together they form the full picture. Not all mods need to modify all 4 files, if you are only editing a limited aspect of a ship, say only the surface of the deck on a carrier, you might only need to extract the _a.dds file, instead of a bulk of 12 files. Be aware that some files (such as gun turrets, torp tubes, radar arrays and other small objects) are commonly shared between multiple ships. Editing one such file will affect the appearances of multiple ships. To avoid unwanted edits, one will find the advanced modding technique "PnFmodding" useful with which one may easily control the scope of effects. Learn more about PnFmodding with this introductory guide I've written. what does each of the .dds file type do Here is a brief description of what the files do. Notice the x in _x.dds indicate their role in the ship texture package. a.dds controls the skin of the ship. Most of your interests will fall here ao.dds is "ambient occlusion " that helps the game to load a shadow effect mg.dds controls various parameter of the "specular" map, elaborated in the next section n.dds are “normal maps”. The blue texture files allow you to create dents and grooves on the surface [pitfall] Some ships (usually premium ships) has extra files that ends in .dd0, .dd1, .dd2 in addition to the .dds files. They exist as more elaborate rendering files for at different zoom levels. In this scenario, you are recommended to extract the files ending in .dd0 (the file with highest resolution), and then renaming the file extension from .dd0 to .dds before proceeding. Editing Texture files Using the Image Manipulation Program of your choice, open the .dds file you wish to edit. I won't go too deep into the technicalities of the software, but I will give share insight to how to use these files and some tricks. [Pitfall] As mentioned above, despite the editing power,Photoshop with Nvidia DDS plugin will have some compatibility issue with transparent texture. If you so prefer using Photoshop for editing, I would recommend first using Paint.NET to convert the DDS file into a PNG file , and then edit the PNG file in Photoshop. _a.dds (skin) This is probably what most mod creators will focus their attention on. Modifying this texture will directly modify the hull on the. The first thing you want to do with the a.dds is to identify where the parts of texture files are mapping to the ship. Some ship texture files would be more straightforward and some might not be so easy to decipher. Identifying the bit of superstructures is usually time consuming as they tend to include small and similar fragments of textures. The picture above shows a rough breakdown of Asashio's texture. Be aware that some textures are mirrored to the orientation of the in game rendering. Flip adjustments accordingly when you are editing these areas. Mercifully, esteemed Fellow mod creators TheKingOfUm(EU server) and IsamuKondera(EU server), has created elegant solutions to aid the process of identifying texture parts. For the sake of tidiness, I've included their solution in the Spoiler drawer below. Click to see the spoiler content TheKingOfUm: IsamuKondera(EU) has suggested exporting the 3D model to obtain the UV map with primitive/object converting tools to directly edit the files as 3D objects. Details for this method will be added later. Notice that, due to the way the WoWs rendering engine works, the game will interpret the texture brighter than it’s in the image manipulation software. This would be self evident when you check out the white areas on the flag.dds and some material that appear as white, where the “white part” has a brightness value of less than 70%. If you are importing textures directly and pasting them on the model directly, you might like to reduce the brightness of that layer ever so slightly to match the brightness level. Of course, if you are going for a “cleaner” artistic direction, or is making a glow-in-the-dark mod, you might safely ignore this piece of advice. _ao.dds (shadow details) _ao.dds are used to create fine shadows on the 3D texture. _mg.dds (specular) _mg.dds files has multi-fold functions. It determines the shininess and color of reflected environment light. Each pixel’s RGB values acts effectively as the local parameter of the area. For each pixel’s RGB value: R controls roughness, the material gets smoother when R increases G controls reflection strength B controls camo/glow strength An common application of the .mg dds is to edit the texture map's various areas to partially/ completely disable camouflages. For example, in my Historical IJN DD camouflage mod, I exploited this property of mg.dds to create "cut outs" on areas affected by the ship camoufalge. ...which result in this effect Alternatively, if you are making a glowing mod, manipulating the B value is one of the way to achieve a glowing effect. _n.dds (normal map) As outlined above, the function of normal map is to create subtle dents and grooves on the model surface. In order to create the depth effects, Photoshop’s DDs Plugin includes a filter that can automatically generate Normal Maps for a _n.dds. I also believe that the GIMP dds plugin provides similar functionality.you might manually edit the texture color should you so prefer. Unfortunately, my computer seems to have some issue with the Normal Map Generator, so I cannot demonstrate how to create normal map right now. Nevertheless, web searching with keyword “Normal Map” should reward you with plenty of tutorials. Exporting and loading them in game Now that you are satisfied with the edit you’ve made, you will want to export the texture files for game-play and sharing. Simply Click "File>Save As..." in your menu and select [.dds] in the "save as type" drop down menu. You will encounter a pop-up box prompting various parameter for the .dds file. Preferably, you should choose one of the DXT formats with alpha (transparency). While some of the alternative setttings like A8R8G8B8 may return higher quality, they comes also with troubles in the form of compatibility, larger file sizes, longer loading time and worse of all, WoWs engine will refuse reading some of them, leading to a crash/ failed battle loading. As such, you are advised to use DxT formats. [Very important!] Ensure that you have the appropriate file name and file paths when saving your files. [Very important!] Ensure that the file you create has the same dimension as the original files. An alternative when using Photoshop to edit files is to first save the texture as a .png file, and then use Paint.NET to convert the .png into a .dds file. The advantage of this method is that, for reasons unknown to me, generating .dds with Paint.NET results in a file that’s slightly smaller compared to files output from Adobe Photoshop. After you saved, the files to res_mod\[game_version]\ with a suitable folder structure, the game will automatically. Hint: texture mods usually does not require a game restart to load. For more an efficient development process, open the game and load all the relevant files into res_mod, and edit the files on the fly. To refresh your texture edit progress, simply save the .dds, load another ship by clicking another ship in the port, and click the ship you are modding again. Your modified textures should show up immediately. [End of Texture modding Guide] Thanks for reading through my humble guide to texture modding.
