How to save hair texture

Can anyone pls tell me how to save hair texture this one I try to save it as dxt5 but it says error pls tell me

Give me a screenshot of the list of the available ways to save that file so I can point it out to you. I haven't modded the game in a very long time so I'm a little rusty. You can always wait for somebody to answer your question, I suppose.

I use nvidia dds plugin

The 8.8.8 RGB I think.

its still not working when i import it to the mod tool

Try the 8.8.8.8 RGBA

Thank you so much its now working

No problem.
