Interesting that opening the PSD in GIMP , then re-saving it from GIMP will allow it to open in TVPaint with layers .
But what I can't figure out is why the original PSD file won't open in TVPaint with the layers intact. I've tried to reproduce the issue on my end, but I can't reproduce it . All of my PSD files saved with multiple layers will open in TVPaint with the layers intact. (which , of course, is a good thing ! That's what we want ... but it's a mystery to me why some PSD files would not open properly in TVPaint ... could it be a Photoshop (and TVPaint) running on Windows vs. Photoshop (and TVPaint) on Mac thing ? )
