You’ve added static meshes to an array but where is the script that creates the components? You’d normally have something like that in the Construction Script.
Either add a Static Mesh Component from the Add Component dropdown manually. Or run Construction Script that creates and attaches components dynamically.
I’m trying to add static meshes components with an additional arrow component from a user created array to the root of the actor but for some reason they are not appearing in the details panel when i’ve added new ones and nor are they individually editable in any way in the world, though they are appearing physically in the world.
Any help appreciated,
Harry.
thank you, makes sense!
