Animated Material tag is "Unsupported Material"

[NOOKTA]

Hello,

I'm working on a simple animation, which has a cube changing material on impact. The material change happens via material tag and keyframing the "material slot". I attached the simplified scene. When rendering frame 0 it works properly. When rendering frame range or any frame in the animation I get the "unsupported material" pattern in the frame buffer.

Can somebody help me with this? Is there a workaround for this to render?

I haven't had the chance to try this with a more recent C4D version or a daily build.

Looking forward to your help!

Hello,

I will log this internally, this is definitely a bug.
However, there is a workaround if you keyframe all problematic frames (all those before the last material change), by pressing the material tag material selection animation node, it will work correctly.

Additionally, if you set the Animation Dope Sheet interpolation to Step (attaching image), this will also fix the issue.

Let me know if I'm not making sense.

Thanks,
Jan
