The main STAIR BUILDER code was created by Reallusion -- G-Tools has merely added a GUI front-end to make it easier for end-users to enter and change the stair parameters.  The original Reallusion code can be accessed here, along with a detailed explanation of how the program works:  https://wiki.reallusion.com/IC_Python_API:Linear_Interpolation

STAIR BUILDER also makes a great accompaniment to the G-Tools BUILDING BLOCKS Plug-In!

INSTALLATION:

2. Copy (or move) the unzipped PLUGIN folder into the following folder (this example assumes that iClone is installed on your C: drive under Program Files -- you will need Administrator rights to copy to this location):

C:\Program Files\Reallusion\iClone 7\Bin64\OpenPlugin

3. Open iClone to refresh the plug-in list (plug-ins installed while iClone is running will not be shown until iClone is closed and re-started)

INSTRUCTIONS:

2. Open the STAIR BUILDER plug-in (Plugins> G-Tools> Stair Builder)
