I have a Blueprint that contains multiple instances of a mesh that I created with the UE4 Modeling plugin (the one that’s in beta status, introducing a Modeling mode in the editor). Everything is working as intended, but I’ve run into two challenges. The first of these I have worked around on my own, but wanted to mention as beta feedback. The second I haven’t solved yet, hence this post seeking advice. I’m coming to UE4 from other tools, so please pardon a question that is probably rather elementary. (I did RTFM but didn’t find an answer there.)
First, there doesn’t seem to be a way to invoke the Modeling mode when inside the Viewport of a Blueprint. Perhaps this is possible, but I couldn’t find a way to add the Modes selection to the toolbar in the Blueprint Editor. I worked around this, after some experimentation, by dragging the original mesh asset into a level in the main Viewport, then editing it there.
Second, I can’t seem to propagate changes of a mesh asset into a Blueprint that has multiple child components (Static Mesh Actor) that refer to the mesh I have edited. I’ve tried doing a “save all” as well as making sure the mesh that I edited is actually the one to which the BP refers. Even restarting the editor doesn’t help. I feel as if I’m missing some really trivial step here, but I didn’t see this discussed in the online docs. Can someone point me in the right direction?
I don’t think this is directly relevant, but one of the changes I made to the mesh was to add three material slots. The instances in the Blueprint don’t show the additional slots in their Details panel, nor do they reflect changes to the default material instances I assigned on the mesh asset.
As a meta-question, I’d also like to know if it’s possible to have a BP not show its components (by default) in the World Hierarchy window. I’m going to have a lot of BPs that contain multiple child components and even hierarchies of Scene Actors, and since these things aren’t directly selectable or editable in the main Viewport, I’d like to simply hide them. I know how to collapse the BP in that window, but by default these are expanded which leads to massive editor clutter.
Thanks for any recommendations or pointers to docs I’ve overlooked.
