I'm looking for a way to use a displacement map to "cut" a logo into a part. As far as I can tell, the displacement map only allows a positive extrusion.
let me know if I am not clear enough on what I am asking.

displacement allows for positive and negative leveling as well as directional specification depending on the map you are using. For the most basic 8 bit black to white map 128 means no movement, 0 maximum negative and 256 maximum positive (the maximum is specified in renderer parameters or if you use it as modifier in the modifier settings).
Overall tho my philosophy on displacement mapping is to only use it if you either really need to cut down on poly count or if you need geometry characteristics that are easily generated by progressive mapping but time consuming to model. while its a great technique in some areas it does have its pitfalls, most prominently the rasterized state of bitmaps which if not treated with care can cause jaggyness, bad distance filtering and overall distorted look.. so for something as simple as a logo id rather figure out something with splines rather then displacement mapping.

in normal people language ...have a black background with a white logo, then put it in the displacement slot with a negative value i.e. -5

Thanks for the replies.
Okay, switched over to Mental Ray instead of Vray and it works great.
It looks like there is a difference between mental ray and vray in the way that they handle Displacement.
Any thoughts on how to do this with vray?
