Set includes:

• Channel 'lateral' marks [red and green, see below for explanation of which], for going either side of a channel
• Preferred channel lateral split marks [red and green with the secondary a band on the other], for where a channel splits
• Safe water ('fairway') marks [red and white], usually marks the middle of a channel
• Special marks [yellow], mark a range of things not otherwise covered, e.g. for races
• Isolated danger marks [black and red], as the name suggests, could mark a wreck or an outfall for example
• Cardinal marks (North, South, East and West) [black and yellow], indicate where the safe area is, e.g. a north cardinal mark means the area to the north of that mark is safe.

Each marker post is set up in a scene in the ./parts/ folder:

• Two sets of marker posts are provided. One is cyclindrical and the other square-profile (chamfered) posts.
• Where System A or B is not specified, the same appearance applies to both areas.
• All posts are transformed to a notional water line at (0,0,0) and so extend underwater. Texture includes underwater 'wear' and fade out at the waterline.
• Poly counts vary depending on the specific item but are all <1500 poly each.
• The material is provided with a normal-mapped texture to emulate a worn wooden painted surface.
• Colliders set up on each.

A series of 'demo' scenes have been included which were used to generate the preview images, and which show you how you can use them with your water and ground meshes. Reminder, y=0 is the water level, not your ground level!

IALA System

The International Organization for Marine Aids to Navigation is the international body which specifies the style, visual and requirements for buoys and marine navigation equipment. For historic reasons there are two systems:

• IALA System A: Used by most of the world. Port is red and starboard is green. (e.g. image below)
• IALA System B: Used by the Americas and parts of East Asia. Starboard is red and port is green.
