How can I fix multiple objects overlapping in render.

Hi,

The problem is quite hard to explain. I will share you some screenshots to help you to understand. I have to render two Mountains. They are both created with height maps and the grids that are displaced are at different positions. Each of them render perfectly when I render them alone, but when I render them together, they overlap. So, the mountain in the back clip the nearest mountain. How can I fix this? Thanks.

You need to expand the bounds of the displaced meshes, see https://support.solidangle.com/display/A5AFHUG/Geometry+Properties+%3A%3A+Displacement#GeometryProperties::Displacement-BoundsPadding

You should set the bounds padding to the maximum amount of displacement.

Note: in your case, the bounds will not be as tight as they could be because it's going to expand a lot in all directions, whereas it would be preferable to have bounds expanded only in the direction of the displacement, I'd be interested to know if the performance is good enough for your scene.
