Have a look at this thread, see if it may help. I have a picture in it that utilizes a vascular map in both P4 and P5. I'm pretty sure though that for some reason displacement mapping requires the bump map to be inverted (or just use a negative number). Here is another thread that has info about the inverting of bump maps in P5 displacement. http://www.renderosity.com/messages.ez?Form.ShowMessage=908702
