Heightfield mapping issue

[good4design (jahn)]

Hey Rhino community

Does anyone know why i am getting this grid material mapping texture on a water surface I made with heightfield- same effect occurs on surface and mesh and is regardless of control points.

Any ideas

That looks like a low-res texture being used there. If you used a Rhino procedural with resample you should make sure that the resolution is correct. Let me find an older thread with a similar looking problem, maybe it is what you experience.

The thread I mentioned:

Displacement Mapping Quality

You are downsampling from 3006x2308 to 128x128 (the U and V values). And that is then applied to your surface. The squares you see are pretty much the pixels of the resulting texture. You should use much higher values. Probably 3006x2308 with a bigger blur radius. Here a version with U 3006, V 2308 and blur radius 0.1 [image] And for fun a quick render in the Raytraced viewport mode of Rhino 6 with Afrikan polished teak material applied: [image]

That’s the one

Thanks very much.
