Flag animation - glitches after export

Hi. We are trying to add animated flags, with wind direction and wind speed
conditions. The whole animation works fine - the flag rotates with the wind
and the animation changes with the wind strength, however, in the sim there
are significant glitches in the flag’s mesh. We wonder if this is a sim bug
(we do not think so) or perhaps we are doing something wrong here?

What 3d software are you using ? I made one in blender and the animation works
well

if you using transforms… you will get problems like this… only bones +
skinning is supported as long as you also use uniform scaling… S.

Yes, we use bones for that. The problem seems to be about the interpolation of
animation stages.

The question is about MSFS, not Blender. :slight_smile:

Once you get it working nicely in MSFS, would you be willing to share a .blend
file with only the flag, for others to learn from? Personally, I am not
planning to animate flags or other “soft” things (like pilots or other
people), but I need to animate a large number of individual relatively simple
and trivially moving objects. (The primary and secondary nozzle petals on each
of the engines of the aircraft I am working on.) I now have each object
animated separately (but using the same name for the NLA track, of course). It
would perhaps be simpler and more efficient to have them as one mesh and
instead animate the vertices for each petal so that the end effect is the
same. On the other hand, what I have now does work.

We tried both - 3ds Max and Blender. Apparently, the solution was to remove
one of the animation steps for a low-speed wind. Anyway, it seems like a
potential bug to us.

Hello, Can you please elaborate on this? I need to remove animation step from
xml or from blender? Thx.
