This beginner tutorial models a low-poly barrel entirely inside Unity using ProBuilder, then textures it with artwork made in Photoshop. You start from a simple cylinder, reshape it with face and vertex tools to get the classic bulging barrel silhouette, then build materials and use ProBuilder's UV editor to lay each strip of wood onto the texture so the faces do not all look identical.
Install ProBuilder and create a cylinder
If ProBuilder is not installed, open Window, Package Manager, search "pro," and click Install. Open the ProBuilder window from Tools, ProBuilder, ProBuilder Window. To create the base shape, right-click (or control-click) in the hierarchy, choose ProBuilder, and create a Cylinder. This gives you a low-poly cylinder you can keep simple. ProBuilder's scene toolbar gives you four selection modes: whole object, vertex (individual points), edge (lines), and face. With any of these you can hold Shift and drag the move tool to extrude new geometry.
Shape the barrel body and lid
To create the bulge, switch to Face mode, Shift-click to select the band of faces around the middle, then use the Scale tool with the proportional (gray) handle to push them outward slightly. For the top, select a top face and use Grow Selection to grab all the top faces. Hold Shift and scale inward to inset a ring, do it once more for a thinner inset, then switch to the Move tool and nudge that inner face down a touch so the lid looks recessed. This keeps the silhouette low-poly while reading clearly as a barrel.
Make and apply the wood material
In Photoshop, paint a wood plank with a metal band and save it into the Unity project. Create a material named barrel, drag the wood art into its Base Map, switch the workflow from Metallic to Specular, and pull the Smoothness down so it is not shiny. Drag the barrel material onto the model. By default the artwork tiles onto every face, which looks repetitive, so the next step fixes that with UVs.
Lay out UVs and add a separate top material
In Face mode, select the faces that make up one vertical plank and open the ProBuilder UV Editor. Use Merge Faces to combine each plank's faces into a single strip, then scale and move each strip onto the artwork, sampling slightly different areas so the planks vary. Use Grow Selection plus Merge Faces on the top and bottom to simplify them. For the top, save a second wood texture, create a barrel top material (Specular workflow, Smoothness all the way down), apply it only to the top faces, and scale those faces to fit, giving you a clean low-poly barrel.
