Render Flickering on Book-Animation with Armature

Support Lighting and Rendering

Hello,
I have created an animation in which a book opens and a few pages are turned. However, when rendering, I see an error at frame 79/80 on the inside of the spine of the book. Only one frame long. What is this?

And secondly, in the first second (frame 55-58) there is a strange reflection on the inside cover of the book. How does that happen?

0080

[edit]
if i change the thickness of the cover from 0.001 to 0.0011 the flicker is gone. Why that?
the strange reflection on frame 55-58 is still there :frowning:

When I look at the first video the issue seems related to motion blur.
Hard to tell you what it is exactly without digging into the file.
It’s either an animation issue, or some modifiers that change the mesh.

Try to apply some modifier and see if the issue is still here.
