Create a 2D texture array in a script

Texture2DArray

// Set the 2D texture array parametersint width = 32;int height = 32;int slices = 8;TextureFormat format = TextureFormat.RGBA32;bool mipChain = false;// Create a 2D texture array with a width and height of 32 pixels, and 8 slicesTexture2DArray textureArray = new Texture2DArray(width, height, slices, format, mipChain);

Example
