Cubemap.SetPixel

説明

ピクセルカラーを座標 (face, x, y) に設定します。

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

using UnityEngine;

public class Example : MonoBehaviour
{
    public Cubemap cubeMap;

    void Start()
    {
        // Set the pixel at (0,0) of the +X face red.
        cubeMap.SetPixel(CubemapFace.PositiveX, 0, 0, Color.red);
        cubeMap.Apply(); // Apply the stuff done to the Cubemap.
    }
}
