And another powerful NEW feature called 'Bake Surface' allows you to combine all the various decals and materials you add to a model into 1 efficient set of decals for color, specularity, reflectivity, ambiance etc... making for a more compact and efficient model.
HOW TO USE? After you are done with your model and feel it is final, right click on it's name in the PWS and choose 'Bake Surface' (V16+) You will notice new images are added to your project that correspond to new decals on your model. You can delete previous decals and (most) materials... it is always safe to 'Save As' during this operation.
