Texture3D.SetPixelData

Parameters

Description

Set pixel values from raw preformatted data.

This function fills texture pixel memory of one mip level 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, depth and data format. Unity throws an exception otherwise.

Фактически, функция Apply загружает измененные пиксели в видео-карту.
