| == Simobject texture search paths == | | == Identifying == |
| In FSX/FSXA, the search mechanism for locating any simobject's texture
| | Identify the filename of missing textures for both aircraft & scenery. |
| <br>
| |
| behaves as follows, and continues until a matching texture is located, or the cycle is completed.
| |
| | |
| Entire cycle is repeated '''for every texture called by the model'''.
| |
| | |
| === Searches For ===
| |
| 1) '''file.ext - As explicitly defined in the model.'''
| |
| <br>
| |
| 2) a matching .CAB file, (if CAB exists, will then search contents).
| |
| <br>
| |
| 3) .ext of opposite type, (i.e. if 1) was a .bmp, searches for . dds, and vice-versa).
| |
| <br>
| |
| 4) repeats 2) for the matching .CAB file, then searches for 3).
| |
| | |
| | |
| If not found during steps 1-4),
| |
| <br>
| |
| FSX/FSXA then repeats '''every''' step above
| |
| <br>
| |
| for each fallback path defined, in a correctly written texture.cfg | |
| | |
| i.e. steps through -
| |
| <br>
| |
| fallback.1=..\texture
| |
| <br>
| |
| fallback.2=..\..\..\..\Scenery\Global\texture
| |
| <br>
| |
| fallback.3=..\..\..\..\Texture
| |
| | |
| | |
| The search sequence will repeat whenever the model requires a reload.
| |
| <br>
| |
| e.g. If the viewport is cycled from VC/2D to external.
| |
| | |
| === Example ===
| |
| An IRL FSX/FSXA example for an airplane model calling a ''.bmp'' texture.
| |
| | |
| ==== Methodology ====
| |
| For this example -
| |
| <br>
| |
| The '''FINDME.bmp''' texture was deliberately removed from the system,
| |
| <br>
| |
| to force FSX to perform a '''full search-path traverse'''.
| |
|
| |
|
| I/O operation QueryOpen actions by fsx.exe, each resulted in a '''NAME NOT FOUND''' error.
| | Adding the following lines to your fsx.CFG in the section titled <nowiki>[SCENERY]</nowiki><br> |
| | | will display an FSX alert dialog identifiying the missing file / object, or render trigger areas. |
| The first 4 paths listed, are for the aircraft's ''native'' folder.
| |
| | |
| Each subsequent group of 4 paths,is for each of the 3 fallback paths.
| |
| | |
| ==== Key ====
| |
| In the ''ProcMon'' logfile extract below -
| |
| * MYFSXPATH - my drive & path to FSX's root folder, (concatenated for clarity).
| |
| * TESTAIRCRAFT - The aircraft folder.
| |
| * LIVERY - The repaint folder.
| |
| * FINDME.bmp - The texture named in the model
| |
| | |
| ==== Logfile data ====
| |
| Search path file-calls for the missing FINDME.BMP texture, (with a valid texture.cfg).
| |

| '''That's a lot of disk thrashing.'''
| |
| <br>
| |
| All CPU cycles utilised detract from FSX/FSXA FPS.
| |
| | |
| == Identifying ==
| |
| To identify the filename of missing textures, (simobject or scenery),
| |
| <br>
| |
| add the following lines to your fsx.CFG into the section titled <nowiki>[SCENERY]</nowiki>.
| |
| <pre> | | <pre> |
| [SCENERY] | | [SCENERY] |
| Line 136: |
Line 31: |
| ShowTriggers=1 | | ShowTriggers=1 |
| </pre> | | </pre> |
| FSX will now display an alert dialog identifiying the missing file / object, or render trigger areas.
