Thanks... I appreciate the quick reply. However, I'm still pretty new at this, and the materials room usually leaves me gasping. Could you be a bit more specific? For the hair prop, there is the usual array of surface values, one of which is "displacement". It does not have a dial, so I assume I would attach a node here, but I'm not sure which one to use. Alternatively, there is also an existing texture file node, but nothing in its options refers to displacement. Mike
