Just a quick question to do with the heightmapping tutorials: Why is the heightmap data stored in an array of bytes?? What is the significance of bytes????? It''s a dumb question i know, but if any1 can help me out with this it''d be great

There is no significance.

Bytes are simply smaller than floats, so less memory is taken up. Since the precision of floats (or some other type) isn''t needed in the demo, byte makes sense.

Also the .raw file contains only raw byte values...

to save some space. but be aware that using bytes can get you some "jagged" parts becouse percision error...

You should never let your fears become the boundaries of your dreams.
