[?] saving dds with alpha channel

[VapoMan]

Im retexturing the the PLA vehicles and when I try to save the textures from psd to dds it says "too many channels to export (5)". The only way I can save it as dds is by removing the alpha channel, but I need that otherwise it makes it super shiney ingame.
So what is the proper way to save the alpha channel?

Also, what is the recomended dds settings when saving the textures?

Thanks.

One way to do so, is flatten image and save it in alpha channels. Save in Dxt5, should work.

Thank you, that works well
