Ocean spectrum per point amplitude

Recommended Posts


I have a ocean Spectrum. I would like to drive the amplitude of the waves based off an attribute I have placed on the scattered points.

I have tried using the "point" vex in the "wave instance"/"amplitude" . But no matter how I try it I can only seem to effect the entire spectrum at the same time. No individual point data is being used.

Am I going about this the correct way. Is there something else I should be doing?

The Ocean Spectrum will expect special attributes if you want to go this way. To drive the Amplitude by hand you need to disable the Amplitude parameter on the Ocean Spectrum and create the @amplitude attribute on your scattered points. Or you can instead modify the @amplitude attribute created by the Ocean Spectrum before it goes to the Ocean Evaluate.
