Hello,
I'm sure there are plenty of ways to do this.
For example, you can add a Corona Sky and add a white non-emissive material onto it and create a Plane with a ShadowCatcher material with white texture Backplate setting (added a screenshot)
Or, you could Use the environment overrides in Render Settings > Corona > Scene environment
You could also use Cinema 4D sky, or even just some light source and a VERY large plane with ShadowCatcher.
Thanks,
Jan
