Details

The parser is failing to read the .tiff file extension from the input string...

bump_map { tiff "earth03_hf2.tiff" }

Results in file not found, but

bump_map { tiff "earth03_hf2" }

will find the file. It might be that it’s not a three character extension?

This task depends upon

  • Field changed: Status (Unconfirmed → New)
  • Field changed: Severity (Low → Medium)

According to the code of SceneData::FindFile() in scene.cpp, in order for POV-Ray to search for the exact filename it must indeed end with an extension of no more than 3 characters (files ending in a dot are accepted though). I.e., currently, the rules for producing filenames are as follows:

  1. If the specified name ends with a dot, or a one-, two- or three-character extension, try the exact specified name first
  2. In any case, try the specified name plus the default extensions for the file format (e.g. “.tif”, “.TIF”, “.tiff” and “.TIFF“)

I suggest to apply the following modifications to this:

  • Only try the exact name first if the specified name ends in any of the default extensions.
  • Always try the exact specified name, if only as a last resort.

Submitted a preliminary fix with change #4813, making sure the exact-named file is always searched for as a last resort (unless it has already been searched for first). The rules when to search for this name first, however, should be reviewed nonetheless.
