Creating a 3D Cube and Applying Textures in Blender
Step 1: Create a 3D Cube
Open Blender and navigate to the default scene. You will see a default cube already present. If not, press Shift + A, navigate to Mesh and select Cube.
To resize the cube, press S and move your mouse to scale the cube size as desired. Confirm by clicking the left mouse button.
Step 2: Unwrap the Cube for Texturing
Select the cube and press Tab to enter Edit Mode.
Ensure all faces are selected (A to select all), then press U to bring up the UV Mapping menu, and select Unwrap.
This action will create UV maps that flatten the cube’s surface onto a plane for texturing.
Step 3: Applying Textures
Navigate to the Shading workspace.
Create a new material by clicking New on the Material tab on the right panel and name it appropriately.
In the shader editor, add an Image Texture node (Shift + A > Texture > Image Texture).
Open your desired texture image through the Image Texture node and connect it to the Base Color of the Principled BSDF node.
Step 4: Adjusting Texture Mapping
In the viewport, change the shading to Material Preview to see the textured cube.
To fine-tune texture placement, use the UV Editor. Switch to the UV Editor panel while in edit mode to adjust UVs, ensuring the texture fits perfectly on the cube.
Export the Cube for Game Use
Ensure the cube is selected, then navigate to File > Export and select an appropriate format for your game engine, such as .fbx or .obj.
In the export settings, ensure Include UVs option is checked to retain the texturing information.
