Hi @dictoon
How it should be implemented? Renderer should see object's mesh in the next and previous frames somehow? Is there any support for this in appleseed or it's just a plugin implementation?

[dictoon]

The plugin needs to specify the different "poses" of objects, i.e. the positions of their vertices at their keyframes.

You can check blenderseed's code to see how it's done. Part of the code is in the Python bindings (export_mesh_blenderXX_pose() in appleseed.python/bindblendermeshconverter.cpp), and the rest is in the Python code of blenderseed itself.
