Motion Blur with Infinite Studio Background Setup.

[Designcoyote1]

I created an Infinite Studio Setup using the steps mentioned here https://help.c4d.corona-renderer.com/support/solutions/articles/12000042047-how-to-create-an-infinite-background-with-the-shadow-catcher-material- and it works just fine no problem about it.

However, I have a number of animated objects in the scene and when it comes to rendering the sequence with Object or Camera motion blur ON objects just jump from their positions & either disappear or intersect with each other. If I turn OFF motion blur (both camera and object motion blur) the scene renders correctly and objects actually show up in their correct positions. I don't know if it's a bug or something but it has happened before and have had to add motion blur in post.

I have attached the scene file. Problems show up when you render the scene from frame 001 - 119 (you can even do a viewport render of the current frame it's on and see). Other frames from frame 120 render correctly with Motion Blur ON & Infinite Studio Setup.

You may have to relink the HDRI in the tex folder to the Sky Object.

iirc, Display Tag isn't supported.

Oh well. Had not thought about that honestly. I guess I just have to look for a way around making the object appear and disappear. If anyone has idea on that please feel free to let me know

SOLVED.

By animating the OPACITY parameter for the respective object materials, I can easily toggle visibility ON & OFF without losing out on the Motion Blur settings.

Thank you!

Hello,

we are aware of this limitation to motion blur for some cases, and we have an internal ticket at (Internal ID=600552583).

Thanks,
