Vray Displacment and adding ploygons to a extruded spline.

[acjwalker]

I am currently playing around with vray displacement. I am currently using it on driveways. The problem I have is when I add vray displacement to my extruded spline and render it with vray displacement it renders with dark black lines across it. When experimenting I used a single plane with a lot of polygons on it and it renders fine with the displacement. It seems that I need to add more polygons to the top of my drive is there a way of doing this?

try putting a subdivide modifier on your extruded spline geometry, or add some cuts in your edit poly going both ways, making sure to avoid long triangles.

 

vray displacement works best with a regular grid of 4 sided polys Iv found.
