Follow these steps to begin applying materials to your model:
Choose the Paint Bucket tool from the toolbox ( ).
Click the Select tab in the Materials screen that appears.
Choose a materials collection from the drop-down menu.
Select the resource you wish to use by clicking on it.
To apply the material, return to the drawing area and click one or more faces.
Follow these steps to move, scale, rotate, or skew your texture: With the Select tool, click the face with the texture you want to edit. Choose Edit→Face→Texture→Position. This enables (deep breath) the Move/Scale/Rotate/Shear/Distort Texture mode.
To copy your selection, go to Edit > Copy in the menu bar or use a keyboard shortcut (Ctrl+C for Windows, Command+C for macOS). Change the cursor to the Move tool icon and select Edit > Paste from the menu bar, or use a keyboard shortcut (Ctrl+V for Windows, Command+V for macOS).
It's quite simple. To select all geometry, press Ctrl+A, then choose a texture and click on any face.
