Gang,
I’m creating a Gallery, my pictures are in .jpg formats, is there a way to create a frame, that I can just plug each picture into? or do I have to create a obj for each picture, or maybe a blueprint the shows the picture?
You could do with a decal, but then you wont get a good result -> so modeling it in a 3d program is the best way 
yeah, I tried the decal didn’t like that, I did create a frame in blender, but i didn’t want to create a frame with the picture in blender I have over 50 pictures to put up on walls
One way to do it would be to have your object in Blender have a multiple material setup.
Make the Frame it’s own Material ID and then have the Picture part be another material ID. This way in UE4 you can apply your frame texture material that won’t apply to the picture portion.
I’m honestly not sure how to set this up in Blender but I believe it can be done if I’ve read some others posts from before.
Here’s a link for the test asset pictured below.
In the image you’ll see that I’ve got two materials for my single mesh. The frame is one material and the polygon for the picture is it’s own material.
If you have any questions feel free to ask!
Or ask ^^
Oh nice! I didn’t know you had one setup for multi-material objects! You are the Blender guy as far as I’m concerned! 
Use multiple materials and then you can change the image.jpg for each instance of the model in the scene.
A small additional tip that will save some time is making sure the picture is material 0. This way you can drag and drop the material directly on the mesh in the viewport instead of going through the details panel.
Also make sure to uv map your mesh for every material id -> for an ordinary picture unwrapping should be enough (select the mesh it in the edit mode - U - unwrap)
