Unused Commentary

An unused commentary track detailing how normal maps were used for a rock's texture.

"The rock texture is an example of using normal maps. Our texture artists in the past have just had to be illustrators, mainly use Photoshop, painted the textures by hand, or use photographic reference. But what we're finding now is we're moving into next-generation content we want to have them also have the ability to model the texture in three-dimensions. So, they'll often use a package like XSI to actually build geometry for these rocks. So the normal map is basically taking a high-res, 3D model and rendering that onto a 2D surface. This way we can create the illusion of an object having much higher polycount than it actually does. So, for instance for these rocks, it's completely flat surface, but the normal map is creating the illusion of them bumping up out of the sand."

Unused Fisherman Lines

The Fisherman was originally going to be a lot more talkative and adventurous. (Hint: Hook/Boat puzzle)

	"That's it. Keep pulling."
	"Keep up with me, laddy."
	"Slip it over the big hook, laddy."
	"Go on, now, pick up the other hook."
	"Grab other hook."
	"[Huffing and puffing sounds]"
	"[Huffing and puffing sounds] I'm gettin' too old for this kinda nonsense..."
	"[Sigh of relief as he slips off the strenuous weight]"
	"Come on, then."
	"Here we go."
	"This way now."
	"Watch your step."
	"Step lightly there, laddy."
	"Easy now."
	"There you go."
	"What's keeping you?"
	"Come along now."
	"Pick up the pace, lad!"
	"This way, lad!"
	"Get out of the water!"
	"Stay clear of the water!"
	"Haven't you had enough of them leeches?"
	"The leeches'll eat you soon as look at you!"
	"Well, as I was saying..."
	"What was I saying? Oh yeah."
	"Now, where was I..."
	"Hm. Anyway..."
	"Well, now, as I was saying..."
	"Well, as I was saying before..."
	"[Various mumblings]"
	"[Whistling and humming]"
	"[Coughing, Throat clearing]"
	"Well, ain't that shame?"
	"Guess I'd better be heading out."
	"Well, laddy...guess this just wasn't your day."
	"Little too close for comfort!"
	"[Breathless panting sounds]"

Oddities

The Fisherman does not have valid ragdoll data, so if he dies, he will just A-pose. Oddly enough, if you interact with a commentary node, the Fisherman will respawn, and stand idling there, forever. This also happens in Garry's Mod, however in Garry's Mod they will not even have a valid hitbox in its A-pose state.
