Cubemap.SetPixel

설명

Sets pixel color at coordinates (face, x, y).

Call Apply to actually upload the changed pixels to the graphics card. Uploading is an expensive operation, so you'll want to change as many pixels as possible between Apply calls.

This function works only on RGBA32, ARGB32, RGB24 and Alpha8 texture formats. For other formats SetPixel is ignored. See Also: Apply function.

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Cubemap c;
    void Example() {
        c.SetPixel(CubemapFace.PositiveX, 0, 0, Color.red);
        c.Apply();
    }
}
