POser tends to be a tad backwards compaerd to the rest of teh 3d graphics world 8 ) for most programmes teh dark/low light/high is the norm.. but Poser prefers teh opposite. basically the higher the lift you want the lighter the shading... Note: the bump wont make any visible differance until the image is rendered... much like transmaps only showing dots until it's rendered.... then you can mess about with the .bum file and contrast to increase/decrease the lift... Cheers
