Click Assign to assign the material to the selected face.If you want to increase the number of colors, click the + button to increase the number of materials.) (In this case, we’ve combined the body, mouth, and eyes, so there are three materials in this object. In Edit Mode, select the face that you want to change, and choose the material you want to apply from the Material section.You can also change the color by different faces.From the Material’s tab, do the following: Add > Cylinder and attach it to both ends of the tires. Choose an edge to creaseEdit Placing the cursor in the 3D View changing to Edit Mode CTRL+TAB choosing Faces (or pressing 3KEY) Changing to Edit Mode. Tires: Add > Circle, to make face from selection, extrude the face.Handles: Add > Cylinder, scale on the z-axis, rotate, move etc.We’re basically finished, but why not customize your model? We added some handles and tires. The eyes look fine as they are, so click Apply and then + to merge with the Body object. If by mistake, you applied the Body’s modifiers before merging the mouth, you can apply the same Subdivision Surface modifier to the mouth and then merge it with the Body. It’s important to understand the correct time to apply modifiers. Keep in mind that if you apply the Subdivision Surface modifier before merging the mouth object, the mouth will not become smooth. Sometimes, while editing a mesh, it’s not always easy to see where the cursor is (especially when the cursor is hovering a light grey mesh). I wish there is a way to do the same in Blender too. Apply the Subdivision Surface modifier to the Body object. Another idea for an add-on: On Windows, it’s possible to change the cursor color (and even invert the cursor color). The mouth has become smoother because the Subdivision Surface modifier set to the Body object has been reflected on the mouth object, which has now been merged with the Body.
