Help with Gimp please (again)

[derekgatt]

Hi,
So i reskinned an sw1500 with gimp 2.8 and in order to do this i had to remove and transfer the alpha channel and as i am pretty hopeless using gimp but improving when i go to save it and then after i submit it in cm on trainz 12 it turns out either full black or full white opacity.l have googled and googled and found the gimp tutorial but to no avail!

Any help would be greatly appreciated.
Thanks in advance, Derek

It may not be GIMP that is causing your problem. Alpha channels in Trainz asset images provide transparency to the image and this, in turn, is usually controlled by the <insert name here>.texture.txt file inside the Trainz asset. There may be several .texture.txt with different <insert name here> filenames. Each of these files is a text file which will usually have the contents (although there are other possibilities) ...

Primary=<imagename>.tga
Alpha=<imagename>.tga
Tile=st

Usually the two image names are the same and the alpha channel, which is part of the .tga image, contains the transparency data.

Perhaps you should check these files first.
