Go to the *Other* button in the top bar and select Mesh Decal.

Once the *Decal* appears in your product tree, you will need to select an overlay image. To do this simply click on the *Overlay Image* area:

Once you have uploaded your decal you would need to do three important steps: * Assign the base mesh (by dragging and dropping it into the *Base Mesh* field): this is the mesh where the decal will be applied. * Assign a base material (by dragging and dropping it into the *Material* field): this serves as the substrate material for applying the image. * Choose a point: Select a point on the mesh where the decal should be placed. You can see all these three points in the screenrecording below.

Assign the base mesh and the base material

## Move the Decal Once you uploaded your decal, you also have various options to * Change the size of the decal with *Size U* and *Size V,* just make sure to keep your aspect ratio match to your original image (to avoid distortion) * Change the exact position of the decal with *Offset U* and *Offset V* * Rotate your decal with the *Rotation* field

## Overview Below you can see a small overview of the Decal options.
