I was retexturing a CLEO speedometer, and created a texture and alpha layer images to be inserted into the TXD file. Problem is, I edited the alpha layer (new fonts for numbers and other things with different shape so I needed to make new alpha) but the program doesnt allow me to add my own alpha layers to the images in the TXD. The speedometer already had its own alpha layer, and when I selected it and clicked import, it only replaced the texture file that that alpha represents and not the alpha itself.
Can someone please explain to me how to edit the alpha in a TXD file? (either with TXD workshop or a new one, but please link any extra needed software)
Thank you so much in advance, this is something I need to learn if I am ever to be able to mod SA correctly.
