Hi
The programs you will need to have are
RDD Pssg Editor
Photoshop or a similar painting program
Nvidia DDS plugins for photoshop (if using photoshop)
DXT bump program if not using photoshop
The Compressonator if not using photoshop.
First best helmet to change as said previously here is a bespoke helmet.
Theses files can be found in the characters files within the game.
Create empty both High and Low files on your desktop as a place to store you custom designs.
Backup the helmet you are going to change first.
Extract the file you are going to change into the High folder and low folder.
Import the texture into photoshop by just dragging the image into the photoshop workspace.
Paint helmet in design of your choice.
Then save as a DDS texture back into the high folder.
Save as half the size into the low folder.
for example high texture 1024 in size, low texture 512 in size.
Now open up the same folder the file was extracted from, and click import button, and import the DDS texture from your high folder, for the high texture.
Once imported, click the save button, (top left in Pssg editor) and save it back to the original destination fom where it came.
Repeat for low texture.
That's it......should be in the game, you just need to select it from the helmet selection screen.
Note the original picture will still be there on the selection screen, so make a note of which helmet you are changing.
AS A FOOTNOTE
I find that saving the file as DXT5 with 2 mipmaps is the best way to go, helps shapen helmets a bit.
Hope this helps, and you understand what I have tried to say.
