Hi Arno, is the "check for updates" function working? I know there have been several updates to MCX recently, but I've not had the "update available" prompt when starting MCX recently.
Both "CheckForUpdateAtStartUp" and "CheckForUpdateUnstable" are set to "true" in options.
Here's a link to one of my dds files.
Saved in Photoshop CC 2019 as 2048x2048 DXT5 DDS with the nVidia texture tools exporter. Imagetool throws an error trying to open it.
