public Color GetPixel(CubemapFace face, int x, int y, int mip)

Parameters

face

CubemapFace
The CubemapFace to sample.

x

int
The x coordinate of the pixel to get. The range is 
0
through (texture width - 1).

y

int
The y coordinate of the pixel to get. The range is 
0
through (texture height - 1).

mip

int
The mipmap level to sample. The range is 
0
through the texture's Texture.mipmapCount. The default value is 
0
.

Returns

Type

Description

ColorThe pixel color.

Remarks

This method gets pixel data from the texture in CPU memory. Texture.isReadable must be 
true
.
The lower left corner of a face is (0, 0). If the pixel coordinate is outside the texture's dimensions, Unity clamps or repeats it, depending on the texture's TextureWrapMode.
GetPixel
might be slower than some other texture methods because it converts the format the texture uses into Color. 
GetPixel
also needs to decompress compressed textures, and use memory to store the decompressed area. To get pixel data more quickly, use Cubemap.GetPixelData instead.
If you need to get a large block of pixels, it might be faster to use Cubemap.GetPixels.
You can't use 
GetPixel
with textures that use Crunch texture compression.

Examples

using UnityEngine;public class Example : MonoBehaviour{    public Cubemap texture;    void Start()    {        // prints the color of the pixel at (0,0) of the +X face        Debug.Log(texture.GetPixel(CubemapFace.PositiveX, 0, 0));    }}
