Sometimes, when using the Auto-Align
feature and having the RC object rotated, the algorithm might have trouble identifying some areas. Resetting the rotation of the RailClone object & performing the Realign
of the base object usually helps.
In case of any further troubles with it, as it's really hard to say, what's happening exactly in your scene just from the provided screen-shot, if possible, please feel free to send us
your scene (ideally simplified and containing just this problematic object(s)) to email@example.com to check it here. In case of a big file size, please use a web sharing service like WeTransfer. Thanks in advance.
