Reskinning a Traincar Example John Weylan The example used here will take you through both reskinning and modifying the GMAX source of an existing model. The basic wagon kuid2: 86627:1654:6 is more than just a basic wagon, it also contains a renamed zip file (change the file type to .zip) with alternative texture files and the GMAX meshes to enable to move the wagon numbers and to change it to a 2 plank, 3 plank, 6 plank etc. very easily. It is also designed to be easy to change the length or change the bogey to one that uses a different height. It has couplings, changeable wagon numbers, it can take air pipes or vacuum pipes, it can carry visible loads or bulk loads. It is slightly more complicated to reskin but not that much. Six steps to reskinning You need to do six things in general to reskin an rolling stock asset first clone the item and the texture group second point the item to the new texture group third do the reskin fourth reskin the texture group fifth adjust the wagon number position finally do the lods. It takes me about ten minutes once the reskin is done. It one relies heavily on textures rather than the shape of the mesh for its effect. All the textures are in one file which is good for performance and it has lod. It is also scripted for couplings, Chameleon for the wagon numbers and is capable of using vacuum pipes. The texture file is modified from one created by Paul Hobbs. The GMAX source and some alternative tga files are included in wagonzip.txt, just change the file extension to zip and unzip it, this allows you to make modifications to the wagon or adjust the position and size of the wagon numbers. Acquire the asset First step is to download <kuid 86627:1654> with its 'texture group' <kuid 86627:1657> from the DLS. <!-- Please note these kuids may still be in the process of being uploaded. ---xxx> CSL <kuid 86627:1654>,<kuid 86627:1657> Clone the asset Then if using TC3 TC we clone the item in CMP. Another method if PEVtools are in your toolkit is to open the asset for edit using PEV's Images2TGA and copy that file to another locale on your HDDs. Revert the original. Note, CM also has a clone capability in the menuing. Image:clone.jpg This basically assigns one of your kuids to the cloned item. If you use the copy method, you'll import the asset, and can like many content creators, use groups of kuids to classify assets by clumps of kuids. For example Jointed-Rail's Justin Cornell (Norfolksouthern32) knows certain asset clumps are bogeys, other couplers, wheels, boxcars, loco's... etcetera all because he's organized his work and planned his kuids out ahead of time. Open the Clone in Windows Explorer Now we open the file in edit in explorer. Image:edit in explorer.jpg In this example we can see a number of folders and ''by convention (back to the original Content Creator's Guide and the original folder organization in Trainz 0.9/1.0–2.4), we are interested in the '_body folder'. <!-- Commented out because image was deleted: Image:folder1.jpg --xxx> Image:bodyfolder.jpg We can see a number of .tga files and generally speaking we are interested in the largest one, cs_skin.tga. Note that this particular model as a couple of alternative cs_skin.tga files that have had their colours changed in a recent version of PaintShop Pro are available in the wagonzip.txt file in the parent folder. To use them overwrite the cs_skin.tga with the appropriate one. N.B. Do not unzip this file without copying it out of Trainz first or CMP will get upset. There are two other associated files with similar names in this example cs_skin_med.tga, and cs_skin_low.tga which are used by the two lower level lod.im files. When we edit the file notice the two different sides and ends. Also note the two squares in the top right that are used to colour parts of the buffers, if you are changing the colour then these must be changed also. Image:Paint shop pro shot 1.jpg If you open the cs_skin_reskin.tga in the zip file you can see the sizes of these sides and ends. For a photo reskin simply resize the side photo and end photos to these sizes and position them appropriately. You will still need to change the colour of the two squares in the top right corner. Image:cs_skin_reskin.jpg To change the colour of the wagon in Paintshop Pro Xi or later use the colour changer tool. Image:colour changer.jpg To add lettering use the letter tool seen here adding white lettering to the grey version of the cs_skin.tga file. Image:add text.jpg There are two other associated files with similar names in this example cs_skin_med.tga, and cs_skin_low.tga which are used by the two lower level lod.im files. When you have finished your reskin resize the image by 50% and 50% to make the med then once again to make the low versions for the lod meshes. Image:resize1.jpg Image:resize 50%.jpg This gives you the basic reskin. This particular reskin uses changeable wagon numbers. If they stay in the same place we just need to reskin the numbers, if they need to be moved we will need to invoke GMAX. To reskin the wagon numbers we edit the files in the texture group or kuid 86627:1657. The wagon numbers themselves are on a plane roughly one tenth of an inch above the model and this plane uses a separate texture file called in this case ssa.tga. The following example uses the texture files from a US Army boxcar to illustrate this found in "25647 ssa.tga" in the zip file. Note the files ssa1.tga through ssa15.tga are used by Chameleon wherever ssa.tga is referenced. So since we textured the wagon number with ssa.txt Chameleon replaces the wagon number texture with the appropriate ssa?.tga. Image:edit in box textures.jpg One difficulty with wagon numbers is matching the typeface used so one technique is to crop them number off a photograph and then edit that to give a set of wagon numbers. When we crop use the largest initial photograph available and if possible crop on a power of two so resizing is not required. 64 pixels by 16 pixels etc. The planes can always be resized so that the cropped image matches the wagon. Image:ssa1.jpg The first step is to copy the crop to a new image. Image:ssa2.jpg Then paste a new copy twice to give us two images to play with. Image:ssa3.jpg Next we cut a single digit out using the crop tool. Image:ssa4.jpg Image:ssa5.jpg Copy this, then activate the ssa1.tga image by clicking on the blue stripe above and paste as a new layer. Image:ssa6.jpg Image:ssa8.jpg Now use the move tool (1) to position the digit where we want it to be (2). Image:ssa7.jpg Finally we save the edited file using save as. Image:ssa9.jpg Repeat the process to create ssa2.tga, ssa3.tga etc. each with a different number. Moving the wagon numbers will be covered in the GMAX part.
