GMod x86-64 generated cubemap downgrade generates corrupted VTFs

[Python1320]

7.5 to 7.4
Example original: cubemap.zip
After conversion broken both in hammer++ (src2013) and VTFEdit (gives an error).

[Python1320]

Regenerated with vtfedit from tgas. Probably not worth fixing so closing.

Hey, thanks for reporting this, I would still like to look into it, so will reopen it.

By quick inspection it seems there were some changes in VTFLib after version 1.3.1, which caused such behavior, the original .vtf that you have provided makes vtfedit to crash too, but in newer versions which use VTFLib>1.3.1 the crash does not occur. So it might be that there is something that wasn't implemented or supported by this tool yet, even though strange that a minor version of VTFLib or vtfedit introduced a breaking change.

Would appreciate it if you could share what versions of vtfedit and vtflib you were using, which has crashed during opening converted vtf image.
