[OPEN][VC4D-061]Why can't I add the background of c4d to affect the refraction effect

As shown in the picture, the background plate cannot affect the refraction of the glass

Thank you, @123456_1

We are aware of this and has been logged in our system [ VC4D-1061 ] We will make sure to contact you if the matter is further developed.

Meanwhile, you could use our VFB Background Layer. One thing to keep in mind is that the Refraction Advance Settings should be set to All Channels: http://ftp.chaosgroup.com/support/screenshots/Cinema\_4D\_2023-10-16\_11-15-03.jpg

Thank you for your reply, but adding a background in vfb cannot produce a refractive distortion effect. This will make the glass look fake
