Can't Apply Decal to .OBJ model after import

  • October 22, 2017

Created a simple box in Newtek Lightwave 3D with separate surfaces for each panel. Exported as an .OBJ model. Successfully imported the model. Went to surface with a custom graphic (.JPEG) and got an error:

"Something went wrong during graphic placement. The decal will be removed."

The same graphic imports just fine on one of the supplied models within Dimension. Anyone else get this?

Correct answer JeanetteMathews

This error usually means there's a problem with the model, not the graphic.  Dimension requires that models have UVs which allow us to project images onto the model, and that the UVs are in the 0-1 positive space.  At this time its out of the scope of our teaching materials for how to fix these errors in 3rd party software, but we are actively working on fixing the issues in Dimension for a future update.

For anyone experiencing this issue on an asset purchased from Adobe Stock, you can reach out to customer care to get an exchange for a new asset.

I have a solution for everyone on this, it will require that you download blender, but blender is free. This is very easy I promise, I've spent less that 30 minutes on blender in my life and I got it right on the first try. I got the info on how to do it here: https://support.shapr3d.com/hc/en-us/articles/4409589482258-I-want-to-export-OBJ-files-to-Procreate-How-do-I-add-UV-mapping-
But for convenience I'll explain what to do.

1.Whatever program you made the model in, export it as an .obj.

2. Open Blender and create a new document.
3. There will be a cube in the document, select it by clicking on it, then hit "X" and then hit "Enter" that will delete the cube.
4. Once you have done this, go to File>Import> and select Wavefront (.obj)

5. Find your file and import it into blender.

6. Across the top menu bar you will see a menu item called "UV Editing", click on it and the screen will split into two viewports.
7. In the right viewport, at the top, you will see another menu bar, and in it will be an item labeled "UV". Click on it and select "Smart UV Project" from the dropdown.
8. A window will pop up that says "Smart UV Project", don't change any of the settings, just select "OK"
9. Then go to File>Export> and select Wavefront (.obj)
10. You are good to go! Go find the newly imported file and add it into your Adobe Dimension project and it will take Decals no problem!

I found the problem occurred when exporting as .obj - creating/exprting the model as an .stl seems to solve the problem...

Has anyone found a solution to this issue? I'm using a .obj with uv's that work fine in other 3D applications. But I'm getting the same error, ...decal will be removed in Dimension.

Any help is appreciated.

Thanks,

Jarrod

    Here comes the fix:

    1. Simply put the .obj file into Photoshop

    2. Click in the navigation on 3D -> Reparameterize UVs -> OK

    3. Click in the navigation on 3D -> Export 3D Layer -> Fileformat Wavefront/OBJ

    After this workaround you should be able to put decals on your 3D model.

      Brilliant! that worked!

      I also was able to bring in a .obj file into photoshop and generate new UV's for an .obj that didn't have texture maps!

        Here's a link to the actual object I'm trying to use. It's pretty straightforward. A box created in Lightwave by Newtek.

        Let me know if you get it working.

        Seems like this box only has UVs on the top plane.  The other sides are missing UVs entirely.  So you can place a decal on the top, but you won't be able to add it to the sides/bottom/front/back.  For decals, objects must have UVs on all the parts, and the UVs should generally be uniform, in the 0-1 positive space, and not overlapping.

        So funny. I am having the same issue and the 3D model I am having an issue with was from Stock.Adobe.com and was listed as being a 3D model for Dimension.

          Oh no!  Can you let me know which asset?  I'll flag it for the content team to take a look.


          Thanks Jeanette! The asset is: AdobeStock_124821805. So far this seems to be the only one I've had issues with.
