AssetActionUtility Blueprints - You can now add a further refinement step in addition to a class filter you can specify Content Browser style filter strings and an error message so that people can see the scripted action, but will know why it's not available to them. Like maybe you have a thing that only can run on non virtual texture streaming assets, you could filter on that tag inaddition to the texture class. #jira UE-165574 [CL 23580250 by nick darnell in ue5-main branch]
