Planar reflections disappearing on play

Try increasing Distance from Plane Fadeout Start and End settings, and also change Angle from Plane Fade Start and End to be closed, with no range difference. Something like:

Distance Fadeout Start: 2000
Distance Fadeout End: 10000
Angle Fade Start: 0
Angle Fade End: 0

When Distance Fadeout Start is 60, then at 0.6 meters away I think it is starting to fade out or is faded out. Whereas 100 for Distance Fadeout End is 1 meter. Hence, standing close to it, or within 0.6 to 1 m away from it is going to fade it out, and appear as not there during render or real-time. I’d try also disabling “Capture Every Frame” so it’s not so performance heavy during real-time playback, or the Play session. It could be getting culled due to a memory or processing overload or something.
