Hi Deusex,
Unfortunately, there is no direct setting you can change in the details panel to affect the quality in that way. In the links provided you can find ways to improve the reflections in your scene though.
We have provided several scene examples to indicate how to achieve a multitude of reflection options that may cover waht you need.
The “Content Examples” map on reflections is very helpful for showing the differences between a bunch of settings.
The “Reflections” example in the market place can show you how it’s been set up in a example game scene to give you the best idea.
The two links I’m providing will give you a clear overview of how to achieve some more effective reflections as well.
Reflection Environment (Link Here) This will give you an overview on how to properly setup a scene for using reflections with the capture object.
Reflections Example documentation (Link Here) This has some solid information on how to use capture actors for your best benefit.
I hope this helps you out!
Thanks!
Tim
