Tropical Lagoon artifacts in renders (SOLVED)

Andrey Pestryakov's https://www.daz3d.com/tropical-lagoon has lovely promos, but when you render a scene there are artifacts, in the form of lines in the sand for both the low res and high res versions.

It would not be too hard to fix these in post, but it's disappointing to see them at all in the high resolution version. I guess I'll keep the product, but other people on a tight budget may want to think about it.

Or maybe someone just dragged something up the beach?

EDIT to add that the scenes seem to work better using the lighting provided by the vendor. See my other image, two posts down this page.

    Uh...that doesn't look very good, I hope they'll fix it :(

    There are no chairs or anything that would justify those "dragging lines".

    How does it look with another sand shader?

    I tried a couple of other sand shaders, plus a dirt shader, but the lines remain, and the different shaders look badly mismatched so custom shaders are required for each of the five ground material zones.

     

    On a positive note, the high res scene does render fast, with nothing added. And I've just started a render with the included cameras and lights, to see if that makes a difference.

    EDIT: Here's a render using the vendor provided lighting (meant for Camera 1) and using the Studio default camera. Rendered in 1 minute and 19 seconds on my PC.

    If you use your lighting, then you should use the Render Settings -> Optimization -> Instancing Optimization -> Memory setting to reduce the number of artifacts on the surface.
    You can turn on LOD 2 to add more vegetation.

    That's good to know, Andrey, thanks!

    I'll use that, as I'm experimenting with my own lighting right this moment smiley

    I am sorry that I was critical without fully testing this beautiful product. (Frank)

    In DS 4.11, the work of Iray Optimization has changed.

    If artifacts appear on the coastline during rendering in DS 4.11, then in the render settings you need to set: Render Settings -> Optimization -> Instancing Optimization -> Speed

    When for DS 4.10: Render Settings -> Optimization -> Instancing Optimization -> Memory

    Wow!  That's a significant change.
