I imported an obj. file to Adobe Photoshop CC 2015 and the whole 3d model came as a single layer. It is a 3d racing suit model and I want to delete arms of the suit. I know I could use the quick selection tool and make a new layer from arm parts but since it is a 3d model, this method doesn't work on 3d meshes. I also tried the cross-section method but it too didn't work. I searched everywhere but couldn't find a proper method. Is there a way to select a part of a single 3d mesh, make a new layer out of it and delete it or simply erase a part of a single 3d layer?

  • As far as I'm aware Photoshop can not alter .obj files. It can only rotate/texture them. To edit the .obj file you need a 3D construction app.

  • @Scott Oh... Can you suggest an application that has a tool to select and erase parts of a single entity?

According to Adobe, it's not possible.


To edit the polygon mesh of the 3D model itself, you must use a 3D authoring program.

So your best option would be to use a 3D software to do the job. Cinema4D, Blender, Sketchup, 3dMax and Maya have free versions and should be enough for what you need.


Layer mask works just fine to remove part of a layer

Use a free 3D Program like Blender or similar to edit the .obj and just delete the Polygons of the Arm.
