Oceans and water shaders

I'm trying to create an ocean scene, does anyone have any tips or tutorials to make large waves look more transparent. I can get the look of a choppy sea withe the lake/water shader, but it just looks like a giant lump , no transparency, or proper subsurface scattering. would using the path tracer give better results? here's a sample of what I made. as you see, it just basically looks like rather lumpy terrain. I've tried decreasing the roughness and increasing wave size, but just get strange looking reflections. any help would be appreciatedboatpaint.jpg

Seems like your roughness is way too high.

It should be possible to get a translucent subsurface scattering effect by adding some "Volume 1 density". This will give the light something to scatter off as it travels through the water. Try a value of 1 to start with.

The settings are described here:

This might also help. It's written for the Glass Shader, but the subsurface parameters are similar for the Water Shader:

Some subsurface scattering effect should be visible with both the Standard Renderer and the Path Tracer.
Just because milk is white doesn't mean that clouds are made of milk.

You can also try a mix with the default shader and use translucency. Nice effects can be made with some experimentation. Here's a clipfile to start off with.

Thanks. I realised that last night after playing again.

I'll give the glass shader a look

Thank you
