Created: January 27, 2024  Updated: January 27, 2024

• This tutorial shows how to use Load Unity RAW files correctly. (Download File Example)

Editor Case : 

In some cases, the terrain will not be generated correctly, For example, when exporting the raw file from Photoshop the options are IMB or Macintosh + Interleaved and Non-Interleaved, also there are tow data extensions for RAW files 8bit and 16bit Greyscale. 

When you set a RAW file into the terrain field, new fields will appear: 

Depth : Determines how many bits Unity uses per pixel in the imported or exported heightmap.

• Bit 16: Uses 16 bits (2 bytes)

• Bit 8: Uses 8 bits (1 byte)

Byte Order : Determines how Unity orders the bytes for each pixel

in the imported or exported heightmap. This mainly applies to bit–16 depth heightmaps, and is platform-dependent.

• Runtime Case : 

From GISTerrainLoaderRuntimePrefs.cs we can play with these values : 

RuntimePrefs.Raw_Depth = RawDepth.Bit16;

RuntimePrefs.Raw_ByteOrder = RawByteOrder.Mac;
