I am trying to make a wave with ocean floor. I applied several modifier to generate a wave which is

enter image description here

I don't want the ocean wave down the plane which need to be removed. At first I tried the Boolean modifier to do a difference but it doesn't make any changes. Is there any split or slice tool available in blender to do the same?

The blend file is available in enter image description here

  • $\begingroup$ Boolean should work, maybe share your file: blend-exchange.giantcowfilms.com $\endgroup$

  • $\begingroup$ Hi moonbots. This is just a sample I replicated at home. At my office I have better once which I made using ur tutorial. I will send later. Using boolean I tried but I think due to existing modifiers the waves comes back after difference. $\endgroup$

  • $\begingroup$ you can use the bool tool slice operation $\endgroup$

  • $\begingroup$ there are inner faces in your ocean objects, as if you had already tried a boolean, the boolean won't work if your topology is not good, do you have a previous version? $\endgroup$

  • $\begingroup$ Ok, how do I fix the topology to remove unwanted faces? I have only one version available with me which I attached in the question. $\endgroup$

Boolean didn't work because you have inner faces that make it fail. That said you can limit the Wave modifier to the group you want, to do so create a group in Weight Paint mode (once done you can soften the weight with the Blur brush) or in the Properties panel > Object Data > Vertex Groups > Assign. Then choose this group in the Wave modifier (and also in the Displace modifier if you've used one). Here only the top vertices have been assigned to the group (except the small part that you didn't want) so the bottom won't be affected:

  • $\begingroup$ This is really helpful for me if I want to do the wave change work. But I need to slice the excell bottom part. So I have updated the question again. Please check $\endgroup$

    $\begingroup$ don't you just need to make the bottom flat? $\endgroup$

  • $\begingroup$ This method you suggested is for the bottom part? $\endgroup$
