Texture2DArray Constructor

public Texture2DArray(int width, int height, int depth, TextureFormat textureFormat, bool mipChain);

public Texture2DArray(int width, int height, int depth, TextureFormat textureFormat, bool mipChain, bool linear = true);

Parameters

width	Width of texture array in pixels.
height	Height of texture array in pixels.
depth	Number of elements in the texture array.
format	Format of the texture.
mipmap	Should mipmaps be created?
linear	Does the texture contain non-color data (i.e. don't do any color space conversions when sampling)? Default is false.

Create a new texture array.

Usually you will want to set the colors of the texture after creating it. Use SetPixels, SetPixels32 or Graphics.CopyTexture functions for that.
