glTF save error

[jonathan@…]

The following bug report has been submitted:
Platform:        Windows-10-10.0.18362
ChimeraX Version: 0.93 (2020-04-03)
Description
Exporting glTF files fails (gltf.wite_gltf).

  I opened the attached adenine.mol (saved from a simple search on molview.org), clicked "Save" in the main tool bar, typed a file name, selected glTF as the output format and clicked the dialaog's "Save" button.

  The process is repeatable.  Having the molecule selected or unselected makes no difference.

  Typing "save adenine-molview format gltf" in the Command area successfully generates a valid glTF file.

Hi Jonathan

Thanks for reporting this problem. I have just fixed it now and the fix will be in the next release candidate.
