Messing about with blender fluids I can't seam to create a realistic enough water surface . any ideas cheers ?

do you think presetcentral will be my best bet .

I guess you should be searching for the holy grail, it's easier I guess.
eheh
it's really hard because in 3d water it's really scene dependent. You should try first with dielectric node, and if you have modeled your water in the correct scale, the absorption in the dielectric node works really well. If you find that you need more control then what the dielectric node gives you, go for layers and start with a 100% transparent surface, and play with the Index of Refraction to get a nice refraction. Then use a gradient in the reflection panel with incidence. Low diffuse (can start with zero). Just some tips.

This one might help, or maybe not, give it a go, it's free! :)

Note: It was done for the swimming pool water in the example renders, so probably won't translate perfectly.

Very dependent on your scene- is it for an ocean surface or a glass of water?

I prefer the control in the surface layers. You need an incidence angle grad in the reflection. LW incidence gradient angles are backwards. '0' is suppose to be the polys facing your POV, and '90' is suppose to be the polys angled 90 degrees away from your POV, but you have to think inverted. A diffuse grad is the opposite values of the reflection grad. Dif and reflect values should never add up to more than 100% or it will look glowy luminous. Depending on the type of detail needed, I may also add an incidence angle in spec, and a thickness grad in the refraction and translucency.

Take a look at how fresnel incidence angles work-

is that psplant thing ever comming out?

I think it's been abandoned due to a lack of interest in Presetcentral generally.

Whatever happened to the Worms of Art guys? They did some great stuff.

They are gone as well. I have all of their collection. Shame they were very good.

you should dump it on here :)

Wish i could but probably not a good idea ;););)

Luckily I printed all my Worms of Art links because I referenced them so much!

Tattered and worn, but they are intact!
