Thanks for sweet comments. Please watch a little animation with 2 roots [ame=" https://www.youtube.com/watch?v=rpg8uvK0Jy0"]Root Growing 3D Animation - YouTube[/ame]
There are so many ways to get this done, correctly. Extrude along spline... Path Deform + Scale... Vertex animation... World space modifiers... Ivy Generator... RayFire... Thinking Particles... Grow1... Grow2... This is what you need to do, NOT scale. But I can see this might be a worthless post...
I watching all good crits and working on that. Within a few days the modified version will be posted here. I am working on the video you showin in Post #18
I love how she is disregarding all the crits ppl are making here :D I'm sure she is just trying to mess up our minds (subliminally) with these videos. Creepy.
