To get started in ICR2 track editing, first download the Tutorial Studio, which is a comprehensive step-by-step guide written by Tjerk. Since it was posted in 2008, there have been further discoveries and clarifications that were made in the forums. We will catalog those in this wiki.


Workflow

Different track editors share how they set up their workflow.


Modding tools

Tjerk posts his MRON utility in Post #23 which can be used to simplify the deletion of the MRON section of a 3DO file in order to prepare the file for N2 to ICR2 conversion.


SGE

Pavel shares some beginner's tips, including the files that go into a track and how to draw a track in SGE.

TRKSG

In this thread, fab4 cannot get TRKSG to work and the community weighs in on the solution.


MRK files
