BackToBeauty and VRayReflection element broken in 6.20.06 when using Matte refl/refl

[IDL_WORLDWIDE]

Hey folks - hoping for a FAST fix for this as we updated to 6.20.06 when we discovered the various IES render element bugs and really can't go backwards at this point. This bug affects the VRayReflection element and BackToBeauty when you have an object that's a matte object with the "matte for refl/refl" checkbox checked.

Attached is an example scene showcasing the issue. In 6.20.02 the BackToBeauty and RGB channels match exactly, but in 6.20.06 they do not. The only channel that's different is the VRayReflection channel and it seems directly related to the "matte for refl/refl" object that's being used for the floor.

Any hope of getting this fixed REAL soon? I've got renders due in a few days and my whole farm has been updated to 6.20.06 to fix the IES issues in another project.

Thanks in advance.

It is registered in our bug tracking system (VMAX-14145) and our dev team is looking into it.
Will update you again, when we have some new info.

Appreciate it - unfortunately this bug and the previous IES bug have completely broken our current workflow for both of those projects. Hopefully this can get fixed sooner rather than later.
