Rearrange the order in which paint layers are applied on a model by dragging layers in the the Paint Layers window. This changes the stacking order of paint layers and the appearance of paint in the resulting texture image.
You can also change the effect of a paint layer by dragging it from one channel type to another (diffuse, specular, gloss, bump). For example, duplicating and dragging a diffuse paint layer into an existing bump channel changes that layer’s characteristics to a bump texture, fully aligned with the original paint layer. The amount of bumpiness is dependent on grayscale values in the image and the Bump Depth setting in the material properties.
To move paint layers to a different channel
If the channel type you want isn't currently represented in the layer stack, right-click the layer and select Move Selected To from the pop-up menu, then select the channel type. (You can also select this option from the window menu button
.)
