By adding "__water" to the name of a static shape (or to a layer name), the shape (or all shapes on the layer), will use the water shader in the web scene.
Or to add web scene water effect to models created in CGA, set the material in the following pattern:
set(material.name, "<yourwatermaterialname>__waterparams_<wavesize>_<wavespeed>")
Where <yourwatermaterialname> is your arbitrary material name,
and <wavesize> and <wavespeed> are values.
Here's an actual example:
set(material.name, "myh2o__waterparams_2_5")
One current restriction:
Avoid params with more than one number after the dot (e.g. don't set "waterparams_5.50_10.21" - use 5.5_10.2 instead)
Let us know how it goes,
