DDS Saving problem

Hi everybody,

since I use Photoshop CC 2019 I have problems with saving DDS files that have transparency defined by the Alpha channel. The problem consists in the alpha resulting all white while previewing with the DDS plug-in, meanwhile in Photoshop it's correctly painted. Anyone had the same issue and solved it? Any help would be appreciated...

In the screenshot you can see the alpha in the exporter being completely white, meanwhile in photoshop (on the right) it's correct.

Thanks

Tilen
