Yacht Wake Foam tests

Hey - I mean the bucket flicker.

If everything is okay when rendering just the foam, then it's something about the interaction with the liquid mesh. Could be that in the particle shader you've chosen to render only the subgroup above the liquid, or you need to enable 'disable liquid shadows', or the fog color of the liquid material is too strong, or the liquid volume is not a closed geometry and the V-Ray fog color can't work this way so all foam under the surface is affected heavily by the fog color...

Thanks Svetlin. I will check these items asap.

Here is the test rendering with only sea mesh or only foam:

On vimeo, the foam looks a little dirty, but it is really clean. I would have to make a longer grid also, to leave more "simulated" space behind the ship

'disable liquid shadows' resolved the issue with the black splotches at the end of the grid !
