Hey guyz !
I’ve created my own item (engram entry, blueprint, primal item blueprint…) and I made a custom icon for it, which I referenced in the primal item blueprint.
It effectively changes the icon in the engrams, but the item icon in inventory and the item icon in the description are still unchanged.
Where can I change this plz ? 
Changing the icons for these should be in the PrimalItem_BP. As you are scrolling through, you should see a space for the icon that is in place for the “vanilla” item.
Yep, I already changed that one
But as you can see on my picture, it only changes the icon in my craftables (1st red square), not the one of the item stored in my inventory (second red square) nor the “on mouse over” description icon. 
can you get a SS of the one you changed in the primal item blueprint?
Well, I was going to take a screen shot for you, but I realized that it could be the “Item Icon Material Parent”, which I didn’t pay attention to because it’s referencing a “Material Instance”.
I just tried to change it, and it worked.
Thanks you very much ! 
Hi all,
We are having a similar problem, but I’m lost with regards to your resolution, can you give me a breakdown or at least elaborate on what you mean by “Item Icon Material Parent” cant find anything relevant.
Any help would be greatly appreciated.

Our issue turned out to be different, when exported from photoshop the mask layer was on top, re-exported and jobs a gooden.
