Hello VG, I had experienced something like that with an earlier build of the C3 Beta but have not seen it recently. This may be fixed for the final release now but might have still been an issue with the beta you received. (that's the fun of Betas!) The image above uses both Spline and Vertex objects. I couldn't reproduce it. I'd still contact Eovia and see what they say though. Sorry I couldn't be more useful... Mark
