Displacement Mod. Tessellation creating large triagular folds?

[NRH1981]

Hello,
I'm trying to apply a simple displacement modifier in Sketchup Version 7 to a body of water and the displacement is creating these large triangular folds and wont apply the mesh properly? Removing the shader to look at just the displacement application and this is what im getting?? Weird....
I have tried simplifying the shape to orthogonal/rectangular shapes and eliminating the curved section but i'm getting the same result. Ive tried reducing the length size, upping the no. triangles but again without success.

Ive even tried copying the shape into a new file.... no difference.

Can anyone suggest what might be causing this or propose a solution? I'm out of ideas?

Hello NRH1981 ,

Could you please share a file with this geometry and its Displacement modifier? You can pack the scene (Extensions > V-Ray > Pack Project) and share it in the forum thread, in a private message or through the support portal - https://support.chaos.com/hc/en-us/requests/new (please make sure to mention the link to the Forum thread in the message).

Kind regards,
