Absurdly long export times from blender

Version: N/A

Frequency: Consistently

Severity: High

Context: Using blender 3.6 to export model and textures

Bug description:
Exporting times are extreamly long.
What took 15 seconds with blender 3.1 using 1.1.6 exporter takes sometimes up to 15 minutes with 3.6LTS and 0.3.4 exporter.
It is very frustrating to work with.

Two suggestions:

Turn off the sample animations checkbox

Reduce your animation key frames - If you use 0-100 try scaling down to 0-10 - MSFS no longer needs to have animations 0-100 KF - it works on percentages now 0 to 100%

However Caution - If your animations do work after unchecking sample animations, then either redo the non working animation or you are stuck with checking sample animations.

This is a core blender Khronos code issue and won’t be changed.

Thanks for sugestion. Unticking sampling definitely speed up process. Now export is being done within seconds.
I cant be sure how animations work in sim though as I didnt have time to test it yet.
Strange thing though is that sampling was enabled in 3.1 blender with old 1.1.6 exporter and had no issues with exporting.

Hello @FlyBoy

As @DA40CGDFQ wrote above, this is a Khronos exporter behavior so I’m afraid there is nothing we can do to reduce the export time when the sampling is enabled.
