Solid don't mean opaque. A fully transparent object is solid, but you 
see through it.

In your case, I'd use a height_field using a black & white version of 
your image using water_level to clip the bottom part.
Next, use that height_field in an intersection with a box and apply your 
image to that. You'll need to rotate the image by 90*x or the 
intersection by -90*x so that they are oriented the same way.

It's probably the easiest and fastest way to proceed.
