I've been getting this issue for a while - if i clone a railclone object (copy, not instance), max crashes. It was doing it with Max 2022...I've just swapped to 2023 and it's still doing it. I've noticed it primarily when trying to clone floorboard objects.
Using latest build of RC (it was happening in previous builds too), latest vray 5 build, 3ds max 2023 (and 2022).
do you need a scene file or are you able to recreate this?
