Hello,
just wanna show of a little side projekt iam working on. This will be a Marketplace Asset, that enables you to use any kind of Mesh (Static, Skeletal, … maybe particles) to be used inside an UMG or Slate UI. This is useful if you want to display the model of an inventory item, a player portrait or whatever you want to draw directly onto the viewport. Everything is pure Blueprint no C++
Here is a little proxy gif (til the youtube thing is done) that shows how this could look
here is a quick test with particle systems
