No effect on Console - Adjacency Index Buffer. Precomputed Visibility. The queries are read back from the GPU one frame later, so there is a one frame delay before an object is determined visible when coming around a corner, which can cause some popping. This hampers precomputed approaches which tabulate impulse responses (IRs) to allow immersive, real-time sound propagation in static scenes. Unreal Engine 4 uses an automatic process for culling that uses Scene Depth and the bounds of an object. 在UE4中，可以使用 剔除距离体积（Cull Distance Volume）来设置距离剔除。 2.视锥体剔除（Frustum Culling） 在视锥体之外的对象是默认不会被渲染的，这个不需要我们再做什么了。 3.预计算可见性（Precomputed Visibility） I switched map loading system to streaming levels instead of "open map_name" to have loading screen between level transition however streaming levels disables culling!

Most shooters generate visual interest in their scenes by having lots of dynamic lights, with extreme use of bump mapping, and moving shadows, and . For VisibleAnywhere, VisibleInstanceOnly, VisibleDefaultsOnly: . visibility is no longer unique for every instance - it can be shared between the copies of the object - and the lighting, even though it is unique, it changes at a low spatial rate so it can be stored in much lower resolution. Note: a small blue node was automatically created this is a variable that references the light actor. Then your players get mad.
