Hi Kim,
We have a large nurbs cylinder 100 x 400 deformed along a spline to
simulate at blood vessel.
We have two hexagonal textures on it to show the cell structure, one in
colour and a related one for a displacement map. Because of the twisted
nature of the deformation and the perspective of the camera, a bump map
does not give the right results. The texture is tiled 50 x 240 over the
surface.
At lower resolutions the displacement works fine, but at higher
resolutions it fails to show up at all. The picture renders fine
otherwise, but the displacement isn't showing in it.
For the cylinder I have Geometry Approximation - Surface set to
Parametric u3 v3 - Displacement set to Length/Distance/Angle with Length
at 1, Distance at 0 and Angle at 0. View Dependant is checked ON. Min 0
Max 3
Thanks for any assistance you may be able to provide.

Subject: deformation disappears
We are rendering a high resolution (3200x2400) still from the
animation but the deformation disappears (fades to nothing)
Any insight would be much appreciated.
