[branched] Imported Object Won't Display Decal Artworks

Phillip@K2  wrote multiple pieces to my 3D objects like levers and straps, by exporting it in photoshop it makes my multiple  OBJ into one. Am I missing a step somewhere?

you don't have the same issue so I have branched this post

if you obj has multiple pieces then that is the problem and it has nothing to do with Dimension because the obj has been made wrong for decal work and has to be remade | repaired

option 1 = select the obj in Dimension and give it a new base material, then add you graphic as a fill or decal because the obj will only have one material now

option 2 = remake | repair the obj in a 3d maker like Photoshop, Blender or Maya... my goto is Photoshop and you merge all the materials into one then place your texture images and export the new 3d obj

which one works best will depend on the model and the look you are trying to get from it in Dimension
