Hi Michal,
Sorry for the lack of details, was getting late last night in here. So I've built up a Railclone object a few months ago, 3ds max 2014 x64, Railclone 2.5.0. I am populating a stadium with fans and the main one I have created has people sitting and standing, I want to make a new one with the same people but remove the seated variations.
I have tried cloning the Railclone object, ctrl-v, and this creates a new working railcone object but uses the same style as the original, similar to an instance. If I edit the new style, the old one is also edited.
I've also tried creating a new RC object and selecting the old one, clicking on the "copy style to" button and then copying it to the new one, this is when the No Geometry warning appears..
i can send you the file if you still need it, but it is quite large, 130MB.
Thanks
Eoin
