I have a Lsystem here and you'll notice as it grows the new branches start as thin tubes - i have tried every way I can think of it to make it look like cones.

I keep thinking that if I can just write the correct expression to get the metaballs to shrink it based on approximate distance to the center … but I just can't seem to make it work.

If anyone can please help me to get these branches to look like pointy sticks all the time I would greatly appreciate it!!!!

what I'm really looking for is a way to make just the very tip small the entire time it grows, not just the later generations. See that image I posted - how it's tube shaped at the ends as it grows. I want it cone shaped at the end as it grows.

Any ideas? Anyone??
