Hello! I’m having a very specific problem. Our game has the following structure for items. In this example, I’ll use a Battery. (Like what you would use to power a flashlight.) ItemParentBP (Base Mesh is there, but it’s not the root) → BatteryItemBP → item\_battery\_9volt To make it look like the 9volt, we take the Base Mesh inherited from the parent and change it to that. The problem lay there. For every single item we have, all of their thumbnails are using the base mesh in ItemParentBP, despite changing them in the child BP. This makes all the items thumbnails look the same (in our case, a can of soup.) It’s quite annoying and increases the time it takes to find our classes for our items. There is no option to Generate or Customize Thumbnail when I right-click on the items. I assume this is a bug? Thanks! ---

Have the same issue. Check out the weapons in the Generic Shooter marketplace project for a very relevant example of this. ---

Hi Zaggoth - Thank you for your report. This is currently a known issue, UE-7955 for reference. The issue is currently backlogged in our system, but I have added additional community interest and updated it with your information. As we investigate a solution to this issue, I will keep you informed here. Eric Ketchum ---

Hi Eric! It seems like this and UE-17453 might be related. Has there been any movement on either? They both trouble me, greatly. Thanks ---

@SVR33 UE-7955 is backlogged currently. UE-17453 has a target of 4.12 for a fix, but a fix has not yet been submitted which means that this could easily get pushed to 4.13 if a fix is not submitted before we branch to start previews for 4.12. ---

this is quite old thread, but the problem still exist in 4.19.2, only happen if the parent class has an empty mesh assigned . ---
