i have a well model, problem is that i want it to be deep. Then ground naturally shows/clips thru it. Is it a way to make the ground not render where well is?

the well will be a placeable by the player, so the hole in ground can be anywhere…

possability to make a culling or opacity material and put on a part of the well mesh so ground not showing? want to avoid tampering with ground/landscape material

-or must the entire landscape be set up with the hole material?(isnt that expensive?)
it doesent need to be possible to enter hole… just a matter of culling the ground away/not render/not show it where well is

Yes, this is possible. The well should render the inside to the custom depth pass. You can do this in the rendering settings of a static mesh, so separate the inside from the outside by putting it in a different static mesh.

Set your landscape material to Masked and use the SceneTexture node (set to custom depth), compare this to the actual scene depth to create a mask. If the pixels of the custom depth are further away than the pixels of the scene itself, render don’t render the landscape.
