Macha Posted November 18, 2012 Share Posted November 18, 2012 You could delete by $BBX, $BBY, $BBZ if it has that boxy shape. Otherwise an attribute transfer from the container geometry could do it too. To make that faster you could do it in a vopsop and group in there, then blast it away.

eko Posted November 19, 2012 Author Share Posted November 19, 2012 Thanks,marc.I will have a try. Unforturnately it is not a regular shape. It is just like a flood comes down a mountain.But the camera will be inside the water and rise up the surface of the water.Annoying! Quote Link to comment Share on other sites More sharing options...
ikarus Posted November 19, 2012 Share Posted November 19, 2012 You could sample the distance to the collision geometry onto the mesh and delete anything that is close to it. Quote Link to comment Share on other sites More sharing options...
SpencerL Posted November 19, 2012 Share Posted November 19, 2012 How can I get rid of the bottom and side face and keep the top surface of the water. I have tried the delete node by normal direction.But the top suface is changing and can't get rid of the face totally.Plz help! ray the surface on 'itself' in the 0,-1,0 direction. If the ray doesnt hit anything, then delete the face. This way, it will preserve splashes and such on top of the surface. Ive attached a file to demonstrate. Hope this helps! del_underside_surface_v1.hip 1 Quote Link to comment Share on other sites More sharing options...
