Because the number of Light Probes in a brick is always the same, the larger the distance between the probes, the larger Feb 26, 2018 · What I’m seeing is that right after I bake my lighting for my scene, light probes will illuminate dynamic objects with light coming from all the light sources in the scene, but when I build to exe, or load a different scene and come back, they’re suddenly only lighting using data from emissive objects with the Global Illumination mode set The light does not change much along the length of the road, so many Light Probes would be storing almost identical lighting data to their neighbouring Light Probes. Single, Unity updates the tetrahedral tessellation automatically as part of the load process, because the new light probe data completely replaces the previous light probe data. You can add a Light Probe Group component from the menu: Component -> Rendering -> Light Probe Group. visibleRefelctionProbes, it seems I can only let Unity automatically transfers the per-object light probes and lightmap data to GPU. The more Tetrahedrals in a given area, the more detailed the lighting on the Dynamic GameObject becomes. After reading about the new SRP Batcher, I can’t see how this would work with the new CBUFFER way of doing things Update the internal structure of the Light Probe data in the scene using the LightProbes. Is there a way to switch light probe data at runtime without impacting FPS too much and without unloading one of the two scenes? Tracks I have explored: Light probes off: the object will pick the ambient probe of the last loaded scene only, which is not the right one usually. LightProbeUsage.
