Reskinning with GSkinViewer
For simple reskins, GSkinViewer may be easier and quicker to use than gsmhacking. While it can't do transparency changes or other advanced things like gsmhacking can, GSkinViewer can update textures and show you the results instantly. Which is all you need most of the time.
To reskin a model with GSkinViewer, follow these steps.
Step 1: prepare a working directory
First identify the model you wish to reskin. Copy it and any textures you think you need into some directory somewhere. Now load up GSkinViewer and open the model. The image below shows SWT_ELEM_HIGH.GSM.
If GSkinViewer can't load any of the textures, find the missing files and copy them into your work directory. Then hit the Reload textures button from the Textures menu to reload the model's textures.
Step 2: make your changes
Now you've got all the textures for the model, load them up into your
favourite image editing program. Make whatever changes you ned for the
reskin. In this example I'm going to swap the officer's legs for [furryclan]
white legs. Save any modified textures with NEW NAMES. I'm using
swt_fcl00.bmp to replace
Step 3: replace the textures
Open up the Textures menu and select the textures you edited. For this example, that means all occurrences of SWT_LEGS2.bmp.
Next click Browse for texture and locate your modified files. swt_fcl00.bmp in this case. Finally click Replace textures to see the results of the reskin.
Step 4: tidy up
When you're happy with the reskin, open the GSM menu and Save GSM under a new name. Copy the new GSM and any modified textures to your mod directory. DISCARD the unedited files. The game will pick them up anyway!
As usual, you can send feedback to firstname.lastname@example.org. If you need extra help, feel free to ask but remember to tell me what you've read and exactly what it is you didn't understand. That way I can make the guide better. Mails asking "Can you tell me how to make mods?" will be ignored with extreme prejudice.
