Hey there
I’ve seen in multiple videos and forums where people have something like a picture framed on the wall and they have an option to change the picture of it within UE4. Is this a plugin or something or is there a trick when importing in static mesh assets which gives you this ability? I know you can apply different textures to static meshes but does this mean I would have to import say 20 textures for a single static mesh so I can have different pictures in the picture frame or is there some trick which packs it all in and you can just change a value in the details menu? I do mainly see this sort of thing in architecture videos. Thanks in advance for your help

It depends on the program you use to make the meshes with, (in 3dsmax you need to apply a multi-sub material and set up the right material ID’s for instance)
this way, when you place the mesh, you can put a new shader in any additional slot you made.
Keep in mind, every material applied on a mesh after the first increased the drawcalls by one.
It might be better to actually set up a shader in which you just replace the texture for the whole mesh or a specific area.
If you want more information let me know.
I’m using Maya and I know how to export a model with a single texture but it was the the whole exporting with 10 textures I wanted to know.
Your info was helpful, thank you.
