TGEN - Terrain Generator
Terrain generator (form name : TGEN) There are 6 different sections.
- The Surface group (SGRP) - The Flora group (FRGP) - The Radial? group (RGRP) - The Environment group (EGRP) - The -unamed- group (MGRP) - The Layers group (LYRS)
SGRP - Surface Group
Where all the surfaces are declared.
It's sub-divied into multiple surface families (SFAM).
Each one of them declare mutliple shaders using a surface file.

Here its declares 2 shaders: dirt.rockmud, dirt.rockmund.a1 using abstract/terrain_surface/harddirt.iff
FGRP - Flora Group
Where all the flora groups are decared using appearance files.
Each one of them decalre one flora group using multiple appearance files.

Here it declares a group named 'Granite.Rocks1' wich contains graniteslab of different sizes.
RGRP - Radial Group
I Don't know much about this one yet. (Select Radial Group properties.)
???? - Radial Child
I Don't know much about this one yet. (Select Radial child rule properties, including family name data, child weight, distance, width and height data, and swaying displacment and period data.)
EGRP - Environment Group
Declares the environement

This one decalres a fractal labeled 'oct1.nbias.BaseRolling Height' TODO: Add fractal notes here.
LYRS - Layers Group
Layers & Affectors
Basically the role of layers is to affect the data contained in the different families. They can contain any number of other sub-layers. Their order is important.
A layer deals with the families trough Affectors. There are different types of them, each one has it's own role. Can have Affector for texturing, flora, areas...
Known Affectors
| BREC | Boundary Rectangle | Delimits a rectangle using 4 float: X1, Y1, X2, Y2 (Select rectangle boundary rule properties, including feathering distance, boundary left/right and near/far coords and local water table height, shader and sahder size.) |
| BCIR | Boundary Circle | Delimits a circle using 3 float: Xo, Yo, Radius (Select circle boundary rule properties, including feathering distance, boundary center coords, and boundary radius.) |
| BPOL | Boundary Polygon | Delimits a n-sided closed polygon area using 2 floats (Xo,Yo) for each point. (Select polygon boundary rule properties, includibng feathering distance and including local water table height, shader and shader size.) |
| BPLN | Boundary PolyLine | Delimits a n-sided line area using 2 floats (Xo,Yo) for each point and a float for the width. (Select polyline boundary rule properties, including feathering distance and width.) |
| FFRA | Filter Fractal | Delimits an area generated by a 2d fractal on the ground. (Select filter fractal rule properties incuding fractal family, low and high fractal settings and feathering distance.) |
| ASCN | Affector Shader Constant | Affect a shader using the family_id and the shader_id this family. (Select rule shader and family and feathering parameters.) |
| ASCR | Affector Shader Replace | Replace a shader with another shader (Select rule shader replace families, including source family (the family to be replaced), destination family (the family to replace with), and feathering parameters.) |
| ???? | Filter Shader | Select filter shader rule properties, including shader family. |
| AHCN | Affector Height Constant | Raises or lowers the ground using float for delta and float(scalar?) for slope-smooting. |
| AHFR | Affector Height Fractal | Raises or lowers the ground irregulary using a fractal type from the Fractal Family.Float for delta and float(scalar?) |
| AHFT | Affector Height Terrace | Select terrace height and flat ratio values for rule. |
| AFSC | Affector Flora Static Collidable | Sets the amount of collidable flora. (Select to add/remove flora, specify flora tpe and set flora density for static collidable flora.) |
| AFSN | Affector Flora Static Non-Collidable | Sets the amount of Non-collidable flora. (Select to add/remove flora, specify flora tpe and set flora density for static non-collidable flora.) |
| AFDN | Affector Flora Dynamic Near | I don't know much about those yet. Seems like they change the near/far radial displaying. They're often coupled to the flora affectors, for instance when cleaning an area for a city. (Select to add/remove flora, specify flora type and set flora destiny for dynamic near flora.) |
| AFDF | Affector Flora Dynamic Far | (Select to add/remove flora, specify flora type and set flora destiny for dynamic far flora.) |
| AENV | Environment | Select enviroment group rule properties. |
| ACRF | Affector Color Ramp Fractal | Select rule family and color ramp. |
| ???? | Filter Direction | Select filter direction rule properties, including feathering distance, and min and max angle settings for filter setting to have effect. |
| FHGT | Filter Height | Select filter height rule properties, including feathering, distance, filter low height, and filter high height. |
| ???? | Filter Slope | Select filter slope rule properties, including feathering distance, filter min angle, and filter max angle. |
