I just installed Cinema 4D R18 and Unity 5.4.0f3 don't seem to find it... When I add a .c4d file as an asset, I get the message: "Cinema 4D could not be found. Make sure that Cinema 4D is installed and the .C4D file has Cinema 4D as its 'Open with' application!" Cinema 4D is installed and the .c4d extension is definitely opening with Cinema 4D. Is there a path entry missing? Can I solve this on my own somehow or do I have to wait for an update? Cheers!
