A problem with the length of my animation and the displacement mapping

Hello,
I try to solve two problems but......
My last animation ( https://skfb.ly/6q8Oy ) , built with Blender , doesn't have the same length that the original (1350 frames instead of 1400 ) .
Moreover, if I use a texture in the Displacement channel for one of objects and after saving the changes then the animation is all black (like this : https://skfb.ly/67ZF8 ) !
Do you know theses problems ?
Thank you !

There is another problem :
sometimes the orientation (angular position) is bad , especially when we reload the page.

Animation wise, sketchfab will play your animation at 30 fps, so if you've exported with more or less fps, then it will recalculate the animation to 30 fps, and this might create extra or less frames. But the speed of the animation and the actual length in seconds should remain roughly the same, so no worries there. If there is, then just export with 30 fps :wink:

Oh ! thank you very much !!

The orientation thing, there is a tool under 3D settings to set your scenes orientation ("Straighten model": first tab of editor)
Also if you accidentally click the scene after reloading sometimes you'll stop the camera while it was "entering" the correct position

Yes , I know that . But even if I don't click the scene this problem can exist.

There are many issues detected in my last 3D animation :

GENERIC
The exporter generated actions that are still attached to objects. Cleaning users
osg::clone(const T*, osg::CopyOp&) passed null object to clone, returning NULL.

BLENDER
Update material animations are not yet supported

Do you think that is the cause of the problem with the displacement mapping ?

The problem is caused by the geometries with displacement that have a scale 0 transform on the first frame.

It can be solved from our side.

The fix has been released.
