Am fairly new to Vue (have just bought Vue 5 Esprit in eager anticipation of upgrade to 6).

I've noticed some strange lines in the water plane - see attached image - lines circled in red. can anyone offer an explanation?

Why are they there?
How do I get rid of them?

It's the default water plane under on of the bundled atmospheres, rendered on "Final". I've seen them before in similar renders.

Thanks
Richard
