Linked meshes disappear with animation rendering

First I want to thank the devs for creating and maintaining the Blender Plugin!

I found a critical bug for animation production: Using linked collections from source files and rendering with “Render Animation” (Ctrl F12) causes the linked meshes to disappear on the second rendered frame. With F12 single frame rendering it works, but then (sometimes) motionblur freaks out.

I attached a Blenderfile with the bug in it’s simplest reproducible form. Just open “SceneWithLinking.blend” and hit “Render Animation”. All paths are relative, so it should work out of the box.

The motion blur part is not reproducible every time and seem to happen only in complex scenes, but I assume it’s connected to the first bug, so I think that has higher priority.

My system:
Windows 10
32GB RAM
RTX2080Ti (MSI GeForce RTX 2080Ti VENTUS 11G)
Driver Version: 141.11

Setting the mesh Object Type to "Movable Proxy" solves the issue. We'll look into that, by the way.

That was quick! Thanks for fixing it!

I also tested your suggestion with Movable Proxy in the current version and it completely solved the bug in my scenes. The aperiodic problems with motion blur too. So it's very likely that all other weird problems with motionblur on linked meshes are also gone with the next version. I should have tested Movable Proxy, somehow I completely overlooked that option.

What was the fix? Is the plugin now setting proxys automatically with linked meshes?

No, it was just a fix at code level.
