Coefficients of baked light probes.

// This script adds the contribution of an ambient light and an array of lights to calculate new spherical harmonics // coefficients for all the baked light probes. You can use this for example in the Editor or at runtime to replace // the light probe coefficients that Unity bakes. void Start() { SphericalHarmonicsL2[] bakedProbes = LightmapSettings.lightProbes.bakedProbes; Vector3[] probePositions = LightmapSettings.lightProbes.positions; int probeCount = LightmapSettings.lightProbes.count; for (int i = 0; i < probeCount; i++) { // Clear the probe and add ambient light bakedProbes[i].Clear(); bakedProbes[i].AddAmbientLight(m_Ambient); // Add the contribution of directional and point lights foreach (Light light in m_Lights) { if (light.type == LightType.Directional) { bakedProbes[i].AddDirectionalLight(-light.transform.forward, light.color, light.intensity); } else if (light.type == LightType.Point) { AddPointLight(probePositions[i], light, ref bakedProbes[i]); } } }

void AddPointLight(Vector3 probePosition, Light light, ref SphericalHarmonicsL2 sh) { // Direction from the light probe to the point light Vector3 probeToLight = light.transform.position - probePosition; // Light attenuation between the point light and the light probe. This formula matches what Unity uses for // quadratic light attenuation. float attenuation = 1.0f / (1.0f + 25.0f * probeToLight.sqrMagnitude / (light.range * light.range)); // With the normalized direction and the attenuation, the point light is equivalent to a directional // light in the context of a light probe. sh.AddDirectionalLight(probeToLight.normalized, light.color, light.intensity * attenuation); } }
