Smoothing Groups error importing from C4D, please your opinion

Hey guys,
Would like to hear some opinions please.

Is there a problem in ignoring the error No smoothing group information was found in this FBX scene ?
Considering the mesh looks nice and smooth anyway.
Note that, there is no solution for this, because I am using C4D R13, which does not have or write smoothing groups information in the FBX.

However the model is imported into UE4 just fine anyway, and looking smooth, except that the error message appears.

Apparently, UE4 generates smoothing groups when importing, or it is able to read some piece of information from the FBX.
But strangely, the error message is there anyway.

If I ignore it, would I have any problems ?
