multi sub object material and vray displacement

[tdarcy]

Hi Guys,
looking for some advice .......i have a multisub object material applied to an object and the materials and mapping are being driven by the polygon material ID's, i am now hoping to add some vray displacement (2d) to only some of the polygons along side that materials polygon and mapping ......is this possible as i currently cant get it to work.
Hope this makes sense.

Cheers Tdarcy

I don't think it will work with 2d mapping. But 3d mapping with Use object mtl turned on should work for what you're trying to do. You just need to plug the displacement maps into the displacement slots of the relevant materials.
