Alpha Channel help

[crestofawave]

hi, thanks for the help, but thats a pretty easy one for a button, mine can be around 50 layers, to try and elaborate, i already have RGB and a clear alpha,and alpha1, older gimps, used to drag this alpha 1 to the screen to make a layer in the layers tab, then edit as needed and drag back to channels, flatten image, save to dds and then in game would be anything from eggshell to full gloss depending or the grey colour you used in the editing of the alpha 1 in layers, so by using different shades of grey you could make wood matte, metal glossy.
doing this in the new version does not work, adding alpha to flattened image makes no difference its still all matte.
appreciate you stopping in to try n help tho
