Hi Chris:
IIUC, you want to know which BMP files are mapped onto *VTPP.BGL Polygons by SBuilder for FS9 (aka "SB205") ?
If so, let's use your
Airstrips of Poland package at AVSIM as an example:
https://library.avsim.net/esearch.php?CatID=fs2004scen&DLID=231101
SBuilder Menu > File > New > [Project Name] > [OK]
SBuilder Menu > File > Save Project As > [
Project Name] >
Save As Type: Scenery Builder (*.SBP) > [OK]
SBuilder Menu > File > Append... > VTP BGL... >
Browse / Select:
[airstrips_of_poland install path]\Airstrips of Poland\Polish Airstrips\Scenery\
EPAR_Arlamów_VTPP.BGL > [Open]
In SBuilder workspace: >
Zoom Tool:
zoom in on Airport Background Polygon ("ABP")
In SBuilder workspace: >
Point Tool: >
click to select boundary of ABP
In SBuilder workspace: >
Right Mouse Button: click on boundary of ABP > Context Menu: Select:
Properties...
In Scenery Builder Polygon Properties dialog, we see: > {
VTP2} tab >
VTP Layer: (
4) >
Classes:
128 Y Grass
Now we must identify the texture mapped via SBuilder under the 'friendly name'
128 Y Grass.
This requires a review of additional info on SBuilder and FS9 to find a 'crosswalk' table for mapping Classes and BMPs.
[
EDITED]
In SBuilder a BMP file name is not listed for
128 Y Grass in the Polys or Lands.txt file, nor any other SBuilder file I have examined.
In SBuilder the Polys.txt file has listed items for
Grass, but that file has no explanatory column header record line:
[Texture.1183]
Title=Grass
Color=0 200 50
Textures=128b2su1.bmp
[Texture.1189]
Title=Low Sparse Grassland
Color=0 200 50
Textures=052b2su1.bmp
[Texture.1190]
Title=Cold Grassland
Color=0 200 50
Textures=052b2su1.bmp
[Texture.1191]
Title=Cool Grasses and Shrubs
Color=0 200 50
Textures=009b2su1.bmp
[Texture.1203]
Title=Grass Park
Color=0 200 50
Textures=128b2su1.bmp
In SBuilder the Lands.txt file has a listed item:
128 124 219 044 128 Y Grass, but that file has no explanatory column header record line.
[
END_EDIT]
128 Y BMP file name is not listed in the BglAnalyze31-decompiled BGL SCASM / ASM code, nor is it listed in FS2004 Terrain.Cfg.
However, Terrain.Cfg does list a number of land class definitions involving the word "
Grass", each with a mapped BMP file name.
I am not certain if Christian Fumey had a list in Ground2K, or if AFCAD, Airport, SceneGenX or other legacy utilities has such a table.

Terrain Texture Naming Convention
This section describes the naming convention used by Flight Simulator 2000 for terrain
textures. The naming convention follows this format:
OOOB2SU1
• The first three numbers “
000” are the numeric value for a given texture.
• A “
B” followed by a number (e.g.,
B2), denotes the latitude band in which the
texture resides.
• The next two letters (SP,
SU, FA, WI, HW) represent the seasonal variation of the tile.
• The last number (1) denotes which variation the texture is.
There are some gaps in the numbering system like the one seen between 011B2SU1 and
013B2SU1. These textures are not mapped anywhere, and are not displayed by the terrain
engine.
There are five possible latitude bands, numbering from 1-5. They start at the equator,
(band 1) and proceed northward to the pole (band 5). The southern hemisphere uses the
corresponding numbers (band 5 at the equator to band one at the South Pole).
There are five seasons: Spring (SP), Summer (SU), Fall (FA), Winter (WI), and Hard
Winter (HW). The difference between the two winter textures; WI and HW are mainly
visual (snow in HW) and when they are displayed in the game.
Almost all terrain textures have variations: a unique texture that tiles in all four directions
to the other textures sharing that numeric value (example: 013B2SU3 and 013B2SU1 tile
to each other, whereas 021B2SU5 and 021B2SU5 do not tile to each other).

One might note a correlation between the above info and SBuilder's inclusion of copied FS2004 default BMPs in:
[SBuilderFS9 install path]\Tools\Bmps
Otherwise, perhaps Arno or Richard Ludowise might know if FS2004 has a file that defines this VTPP land class mapping ?
Possibly one may find this info within a class definition BGL in: [FS2004 install path]\Scenery\BASE\Scenery ? (forgot decompiler needed)
Hope this helps get you closer to finding the info you seek.
