    Pictures are worth thousands of words...can you post a render or screenshot?

    Actually, both...a render and screenshot showing your surface settings, one showing your render settings...

    The vertical lines in the tank in the front?

    They could be due to the shading rate...so what are your render settings?

    Or they could be caused by the geometry of the 'water' intersecting the geometry of the tank...if that's the case, try scaling down the 'water'...not much, try 99.9% or 99.8%.

    What do you mean scale down?

    Yep...need the shading rate and the raytrace depth. If you hit All you should be able to get both items in the shot, if you scroll down past the size settings.

    I see shade rate but not raytrace depth.

    It should be 4 up from Gain...Max Ray Trace Depth.

    Up it to at least 4...possibly 6.

    It will slow the render down somewhat, but it will give much better glass, especially at the transition between the glass and the liquid.

    Which set is it?

    You should probably drop the shading rate to about .5, too...

    What product is it.

    I have 3 that I use and they all come out the same. rigid water, liquid pack and the iray shader. they all come out the same. I found a glass that works but water I still get lines.

    That looks like the dystopina containment tank

    Not sure about the center piece, maybe the regenerator?

    Yes thats right its both products. Why? I try to change them and make them completely differnt.

    It makes it easier for people to replicate your problem and find a solution if they can test with the same products you are using.

    try converting the model to SubD and rendering. Do the lines go away? If they do, is that usable? If bits go AWOL, try changing the Edge Interpolation setting under Mesh Resolution in the Parameters pane.

    Select the figure or prop. Edit>Figure(or prop)>Geometry>Convert to SubD. try rendering.

    Yep...all the above suggestions will increase the quality of the render...and geometry, but at a cost of increased render time.
