Animated VrayProxy as Birth Object ?

[glty]

The shape animation loops fine in the file you sent...

If you want it to loop *seamlessly* (not jitter when the end frame loops back to the start frame), that's something you have to build into the source animation. The Shape operator just loops the keys you give it, it doesn't do any blending.

Normally I would recommend just putting a tyLooper modifier on your proxy geometry, but your proxy geometry topology changes every frame so that won't work. Not sure why it's changing, but it does (put an Edit Mesh modifier on your VRayProxy, select some faces and drag the time slider...you'll see the selection go crazy because the vertex/face ordering is changing every single frame). Perhaps wherever you exported the tree from has a setting to maintain topological consistency over time...

Hi,

Really ?, it doesn’t in my end, did you move the timeline past 251?

The tree does not change topology, its just the vray proxy preview mode, if you select the vrayproxy and change the display to whole mesh you can see. 

if you unhide the proxy and scroll the timeline you can see the proxy continues to play past 251, but tyflow does not. Like this video https://www.dropbox.com/s/elp73sg3fasc0v...e.m4v?dl=0
