I’ve tried doing a trick where I extend the size of the culling sphere When this flag is set, Unity culls shadow casters as part of the culling operation. Ok, in my case I got wrong frustum culling in portrait because I was setting the camera projection matrix and probably not setting the culling matrix right. Wrongly occuded blocks are marked as both There’s a shadow-casting directional light in your scene. The way how it works is actually pretty simple and requires a bake step in the editor: - Assign unique colors to all meshes I If you're using Unity 5, the Mesh Renderer component has an option under Cast Shadows called 'Shadows Only', which does exactly what it says - casts a shadow, without visibly rendering The flickering happens because GameObject coordinates become increasingly less precise as they get further away, so the shadow moves in and out of culling range. Real-time shadows have quite a high rendering overhead; any In some spots, when I move cursor to specific viewport some shadows disappear.
