Help on saving textures

I have a bunch of full-perm textures in my inventory. I want to edit some of them, so I do a File > Save Texture As... and save it as a targa .tga file. However, when I open the file (in several different editors & viewers), the tranparent areas in the textures have been converted to black. Is there something special I have to do to preserve alpha-channel information in the saved file? I didn't see anywhere I could set any options regarding the export.

I'm using a 1.19.1 client, if that's significant.

what program are you using to edit the textures.

transparent textures need to be saved as 32 bit, not 24 bit.

Hi,

When the texture is made in photoshop ect, to create transperancy for tga's you need to create an alpha channel, this uses 3 colours to specify the level of transperancy.

Black being complete transperant, grey being semi and white being full opacity, so when you save from secondlife to your computer the issue you described happens.

I believe (if im not mistaken), if you open the file in photoshop or whichever file you use (aslong as it supports alpha channels), click on the chanel tab (in layers pallete), you should see alpha 1, click it to add an eye (in paint shop & photoshop) the go back to the main layer, all that was transperant should now be in red.

If your modifications are inside the red zone thats fine work away, if its not you will need to recreate the alpha channel, to learn more about that visit the textures forum and find the sticky on alpha channels
