We are using Aximmetry version 2026.1.0.
Is it possible to use a Shadow Catcher (similar to the one available in AR scenes) in Tracked Cam scenes?
In our setup, we have a real floor onto which we would like to receive shadows from virtual objects (tables, flower pots, etc.), while maintaining the ability to work with a dynamic sky (Volumetric Clouds, etc.).
We apologize in advance if this topic has already been covered — we would be grateful for any help.
Thank you!
Hi,
The TrackedCam+AR_Unreal_3-Cam or TrackedCam+AR_Unreal_8-Cam camera compounds sound like the right solution for your setup. Their +AR section supports both Shadow Catcher and Reflection Catcher.
In these compounds, the +AR part can be used to render the objects whose shadows should appear over the real-world image by using shadow catchers. You can read more about this here: https://aximmetry.com/learn/virtual-production-workflow/ar-production/unreal-scene-setup-ar/#ar-in-green-and-led-wall-projects
And here: https://aximmetry.com/learn/virtual-production-workflow/ar-production/unreal-scene-setup-ar/#shadow-catcher-1
That said, you may encounter issues with Volumetric Cloud. See: https://aximmetry.com/learn/virtual-production-workflow/ar-production/unreal-scene-setup-ar/#fog
If that becomes a limitation, you could consider building a comparable shadow-catching solution in Unreal.
Also, depending on where the real floor is located, you will likely want to use Window Mask mode. More details about Mask modes are available here: https://aximmetry.com/learn/virtual-production-workflow/green-screen-production/tracked-camera-workflow/studio-control-panel/#mask-modes
Warmest regards,
