+ Updated Character textures (requires updated character FBX with proper UV)
+ Textures: Car trailer & engine
+ Object: Car Trailer (modified their UVs for easier texturing)
+ Shader: Laser PUSH (unused for now)

CHANGES:
> Created child objects for "Laser Holder PULL" for testing two-line and multiple-line line renderer.

KNOWN ISSUES:
> Using 3 or more line renderers significantly reduces frame rate. Please don't use multiple line renderers unless
it can be optimized.

==========
+ Tutorial sign object
+ Tutorial sign textures
+ Temporary texture - Push Brother
+ Temp Fence model & texture (Unity Asset Store package)

==========
CHANGED:
==========

> Pull-Brother temporarily using place-holder texture
  (Final UVs can't be applied until final character model with animation is imported)
> Slight tweaks to terrain (Textures and terrain heights)
> Added extra invisible walls near temp-fence area
> Placed a large pipe near the 2nd tutorial crate to avoid it being pushed
  (Crate must be pulled to corner space to proceed to scaffold area)
> Placed 2 x movable objects near the temp-fence area.

==========
ADDED:
==========
+ Tutorial puzzle (AKA GIF Puzzle) has been built.
+ New terrain added (work in progress).
+ "Resource Bay" objects (for Lift Puzzle) have been placed behind the Scaffold inner building.
+ Several interactable objects have been placed around the scaffold area.

==========
CHANGED:
==========
> Players 1 & 2 have been re-positioned to the front of the tutorial puzzle.

> The object "Resource Bay" now uses 3 x box colliders instead of the custom mesh.
  (Custom mesh was in fact less that 256 vertices, but Unity still rejected it).

> Reduced the Lighting feature "Ambient Intensity" from 1 to 0.62.

> Temporarily disabled two Lighting features to stop unnecessary rendering:
  1. Precomputed Realtime GI
  2. Baked GI

  The above features can be enabled via Windows > Lighting > Scene Tab

=================
WORK-IN-PROGRESS:
=================
- Still need to place more prop objects for visual aesthetics.
 (Please give an update on FPS numbers to see if new scaffolds and terrain have a huge effect on frame rate)
 (Personally, my PC still ran at 60 FPS)
