Hi Umit,
I've just applied a patch that should solve the samplerRect issue for you, I
think I was being too hasty to blame your graphics drivers.
Update your code from:
https://osgocean.googlecode.com/svn/tags/osgOcean-1.0/
<https://osgocean.googlecode.com/svn/tags/osgOcean-1.0/>
Regards,
Kim.

Hi Kim and JS;
Thanks for suggestion. I have tried again and as you said I really need new
version GPU. This is only solution which will resolve kind of these problems.
Regards.

Martins, J-S,
>Here you go. If you zoom in to 400% or so you can see 3 pixels
near the horizon that are really dark. They flicker during the
simulation, sometimes individual pixels, other times it looks like
larger groups.
Yep it's a bug in the library. Looks like a polygon break to me, possibly a
corner piece. I must have been trying to ignore it as it's a nightmare to debug
that bit of code. I'll log it, but it could take a while to find that blighter.
>If you disable godrays, silt and dof (basically disable all underwater
effects) then go underwater, you'll see a black like at the horizon. it
looks like fog is not being applied for a line of pixels at the horizon.
I think this is a fogging issue, the wave tops are probably going over the fog
line and exposing unfogged geometry. Shouldn't be too bad that one.
Cheers all.
Kim.

Kim,
Here you go. If you zoom in to 400% or so you can see 3 pixels
near the horizon that are really dark. They flicker during the
simulation, sometimes individual pixels, other times it looks like
larger groups.
Sorry if this comes through twice, looks like the first one was too big
for the list.
