I've been playing round with textures for my constructions (and eventually clothes designs). Looking in the list of bump-mapping options, I know we has Lightness and Darkness which we can use on our uploaded textures, as well as other pre-defines, but is there any way to upload a user-defined bump-map - either associated with a texture, or just general ones to get an effect on an otherwise smooth surface?

Thanks in advance for any light you can shed on this,
