i'm trying to create an intricate group of very fine lines that resemble tree "roots" and animate or 'grow' on...
i have started by drawing a spline; drawing a tiny circle and then sweep to create something with a bit of depth that will render. is there a faster way to do this? is there anyway to just draw many splines and connect them so that they will be seen in a render? i am currently animating the 'grow' with the sweep 'growth' attribute.
You will not be able to get around this without extra plugins.
Have a look at Solid Spline or Storm Tracer if you want to make spline visible in a rendering without having to work with a Sweep NURBS object.
This will not ease the process of the splie creation, though.
A total different thing might be interesting if you have to do such animations more often. Have a look at XFrog (http://www.xfrogdownloads.com/greenwebNew/news/newStart.htm). It offers organic modelling and animatin of plants within C4D.
