Binary Format
INST is also one of the known sections which can be used in binary format inside streaming IPLs. For detailed information about the format see the format specification in the supposed article.

Limitations
Each game has different limitations. The most important limit for the instance section is the so-called map boundary, which is a notional boundary around the map. Outside those borders no objects will be visible. If an object is intersecting the bounds it may be displayed incorrectly.
