We have almost 100 PNG icons we use in game and the content browser shows them all being pitch black :

It’s really not convenient to work that way.

For all icons it would be more usefull if we could see the PNG’s alpha channel in the preview instead of the empty pitch black preview.

Perhaps it could be done through manually choosing which pictures get a preview based on the alpha channel or it could be done automatically for pictures that have no RGB content?

My PNG icons would show up as ALL WHITE. I fixed it by double clicking the icon, setting the LOD GROUP to “UI”, then save.

See the attached image:

Thanks.  
You can also edit tonnes of icons at once with the edit via property matrix right click option.
