input | Array of float values to be used for Enlighten Realtime Global Illumination environment lighting. |
Allows overriding the distant environment lighting for Enlighten Realtime Global Illumination, without changing the Skybox Material.
The input array represents a cube with each face being 8 x 8 texels and each texel being 4 floats (for the RGBA values of the texel's color), so the size of the array is 8*8*6*4 = 1536 floats.
Note that changing the Distant Environment Lighting Source or Environment Lighting Intensity will overwrite the data set with this function.
using UnityEngine;
public class ExampleScript : MonoBehaviour { void Start() { // Set custom environment data for Enlighten Realtime Global Illumination. const int kCubeSize = 8 * 8; const int kEnvironmentDataSize = kCubeSize * 6 * 4; float[] envData = new float[kEnvironmentDataSize];
for (int c = 0; c < 6; ++c) // cube has 6 sides. { for (int i = 0; i < kCubeSize; i += 4) { int index = c * kCubeSize;
// Fill with default values. envData[index + i + 0] = 0.0f; envData[index + i + 1] = 0.0f; envData[index + i + 2] = 0.0f; envData[index + i + 3] = 1.0f;
// Funky colors on each cube face. envData[index + i + (c / 2)] = 4.0f * (float)i / (float)kCubeSize; } }
// Send the generated environment data to the GI system. DynamicGI.SetEnvironmentData(envData); } }
