Wiki GLTF little update requested

@mitm I think here:

is missing description how in Blender setup animation NLA tracks to export.

today one person on Discord put animations in one track, and there were issues ofc.
So i think it would be worth add mention that for multiple animations, each animation should have own NLA track + "selected one as " to make sure it work.

here i send reference how NLA track should be prepared to export multiple animations:


(how to make it i think its less important, but important is to let them know about this setup important for export)

They should be able to be all on same track as long as there is a couple frames space between each animation. Thats actually the way most tracks are.

I like mine separated but even then they still must be a couple frames space between animations and the timeline must match in length, maybe thats the reason for the problem?

Does the gltf specs say they must be nla tracks? I thought they could be actions also. I vaguely remember testing that and it working.

I am unsure whether the gltf exporter bakes the actions but that’s also a possible downfall.

I will be reworking the gltf document even more when I get back to modeling. Working on getting my servers up so I am strapped for time until that is done.

oh, didnt knew it also work for “frames space between each animation”

anyway, this is also not in this wiki page right?

so i think both solutions should be added into there :slight_smile:

edit: also not sure i didnt seen this baking wiki, its nice.(earlier i needed search “how to” myself)

ofc, it can wait until “rework” you plan, but i hope you will remember to add it :slight_smile:

Yes, I intend to go into great detail on it. I use a 4 frame gap between animations on the track, and the timeline must be equal to the time of all animations added together + gaps.

Note the green line (end of track) equals the time set on the timeline itself of 314.

nice, i understand you will do it on Blender 2.8+ right? :slight_smile:

2.79 UI seems could be outdated for some people even now.

The page has been there but the link to it was left out when I edited the wiki in dec. I just added the link back into the mixamo document. ill go ahead and add it to the big kahuna blender page.


thanks! you do a great job, really :slight_smile:
