#### Summary Occlude edit mode selection behind objects in object mode. #### Problem When doing retopology, you want to be able to select your edit mesh, but only when you can see it. Being able to select geometry behind reference objects is not desirable. #### Solution Make it so reference objects occlude selection, while the edit mesh is pushed towards the view using retopology offset. #### Limitations Poly Build is not supported, because it doesn't use the depth buffer. It behaves the same as normal, unoccluded by reference meshes. #### Notes Selection occlusion is not used when xray is enabled. This is intentional. Pull Request: blender/blender#105498
