data Raw data array to initialize texture pixels with.
size Size of data in bytes.


Fills texture pixels with raw preformatted data.

This function fills texture pixel memory with raw data. This is mostly useful for loading compressed texture format data into a texture.

Passed data should be of required size to fill the whole texture according to its width, height, data format and mipmapCount; otherwise a UnityException is thrown. Mipmaps are laid out in memory starting from largest, with smaller mip level data immediately following. For example, a 16x8 texture of RGBA32 format with no mipmaps can be filled with a 512-byte array (16x8x4).

For runtime texture generation, it is also possible to directly write into texture data via GetRawTextureData that returns a Unity.Collections.NativeArray. This can be faster since it avoids a memory copy that LoadRawTextureData would do.

Call Apply after setting image data to actually upload it to the GPU.
