Hi, is it possible to set in Blueprints the opacity or translucency of a whole actor (so it affects the materials of all its components that are meshes, skeletal and static ones) or do you have to do it material by material? If not currently possible it might be a good addition.
Sounds like you are looking for Material Parameter Collections.
They’ll allow you to do just that: they can be adjusted from blueprints and all materials referencing that parameter will be updated simultaneously.
Thank you, using this with an Opacity parameter will do it.
