Displacement Map Error

[wesm]

Hi,

I've been following the Rfm DVD and I'm having an issue when using a displacement map. I have attached an image of the problem. On the model, I'm using RM subdiv scheme. I've adjusted the alpha gain/offset to get the displacement working. I'm not sure why the black area is showing up in the brow. I created the displacement map using modo's sculpting tools.

Thanks,

Wes

Try add a trace displacement on shape node
Attributes/renderman/manage attributes/
and add trace displacement.

And add on maya displacement node RM displacement attr.
DisplacementShader/Attributes/renderman/renderman displacement attribute

and set it to about 20.
