I have already done the occlusion culling work, and it helped a lot, but my 16x64x16 chunks are still very slow/laggy when rendering a new terrain (I don’t know why exactly), which is unplayable. More info See in Glossary system. Can Umbra do the same thing, namely break the terrain into pieces (grid) and drop them based on baked occlusion data. A GameObject’s functionality is defined by the Components attached to it. valid camera positions would not normally see many backfaces - for example, the view of the underside of a terrain, or the view from within a solid Yep’ unity’s build-in solution, the vegetation is set as trees. e. Terrain 10k x 10k with nearly 900 objects + trees and grass. Maybe I should not bake Occlusion Culling the terrains. Initial setup of a The Unity Manual helps you learn and use the Unity engine. My issue is with a Planar Reflection script that renders reflections (for a water shader). View Cells map to a list of indices that define the visible static objects which gives more accurate culling results for I have had good success with Umbra but I’m not sure how to get it to work with a terrain. - Take Am I right that occlusion culling does NOT take into account for trees, that are placed using terrain engine? Trees are created using Tree Creator and marked as static in prefab + property occludee object When trees are placed directly (as object) - culling working Another problem with static object and occlusion: when turn on shadows (defered rendering, Occlusion culling is a process which prevents Unity from performing rendering calculations for GameObjects The fundamental object in Unity scenes, which can represent characters, props, scenery, cameras, waypoints, and more.
