I made a glass node following a tutorial. At the render view looks very nice, just as I want it.

Somebody help me to solve this please. Thanks in advance,

    $\begingroup$ Check for hidden objects: Alt H. Check for the subdivision modifiers on objects. Looks like there is a rectangular object, which gets subdivded. Subdivision modifiers have differen values for Preview and Render and are easily created by accidentally pressing Ctrl 1. $\endgroup$
