Texture2DArray.SetPixelData

パラメーター

説明

Set pixel values from raw preformatted data.

This function fills texture pixel memory of one mip level and one array element with raw data. This is useful if you want to load compressed or other non-color texture format data into a texture.

You should make the data that is passed the required size to fill the whole texture mip level according to its width, height and data format. Unity throws an exception otherwise.

SetPixelData throws an exception when it fails.
