I built a simple box OBJ in photoshop. Just a simple extrusion. I'd like to place images on each side of the box. I'm ok with placing these by separately by hand since they will be the correct ratio.
Right now importing a demo decal to test the model and it's showing up across all sides in a strange way.
Any tips to prevent this from happening would be helpful. I have a feeling it maybe something in Photoshop before exporting to an OBJ.
Check out what I'm seein
There is possibility in Dn to use Magic Wand selection tool and select each surface separately. That will allow to place graphic separately into each surface.
the underlinning issue is the way you built your box in Photoshop so you now have two options;
Ares Hovhannesyan shows the first option so I'll show you the other ok
when you build your box in Photoshop use the shape tool for the faces and then just extrude the layer... I coloured my extrusions green to make them stand out for you but that isn't needed
p.s, understand that Dimension will only give good results on the faces... the sides of your box are extrusions so they have small area and you should build your box out of all shapes if you want to put images on the sides as well as the faces
pps, we can see the issue clear because you added a vid, so well done!
good luck with it mate
