Scale down ocean guided inputs

Recommended Posts

Hi,

I am trying to simulate an ocean guided flip with a maya scale spectrum (1 maya unit = 10 houdini units).

Since I did not find a way to properly scale down the a spectrum , I am down scaling down all the inputs of my sim :

_ The particles -> Transform SOP

_ The grids (surface, vel, guided_sink, guiding_surface) -> Transform SOP + scale down values

_ In the solver I scaled down all the parameters linked to the Ocean source (particles sep, boundaries,...)

My issue is despite those adjustements the waves are "breaking" and not matching closely to the spectrum. It looks like they are just affected by the vel field like a standard force and not really guided.

Please let me know if you need more informations.

Cheers

hi - this is not good idea u scale everything - when u import ur model into Houdini just scale 0.01 value  (transform sop -- and if your model is correct in meter it will be work  ).

then continue for other stuff without changing anything
