I have never before even open the Export persona, didn't see any use for it. After this short and sweet class I know how to use it, and I know I will use it. An example I've immediately try out:

I have some doodles in Krita (drawing SW)

Export them as PNG and place the image in Affinity Designer. First I need to rearrange them in Pixel persona 

then the slices were set in the Export persona

and exported

Then I put them in the Asset studio and can use them whenever I need them :)

 

Thank you Tracey for this very useful class.
