Hi everyone,

I'm a beginner in Houdini, and I need some help.

I have a scene where a line grows over a logo using Vellum Hair. My question is: how can I make the lines grow randomly?
Right now, all the lines grow at the same time, but I'd like them to grow at different times in a more natural, random way.

File attached.

Thanks in advance!

Here's one way to do it. Generate a start and end frame attribute for each hair strand. Then loop through each hair and use the frame number to fit the start/end range to 0-1 for second_u.

Hi,

a slightly different approach but basically the same thing as above - generating a random carve attribute on each primitive(has to be on primitive level not point).

Guys! THANK YOU SO MUCH! It looks perfect!

You are so kind to take time to help me with this!

Wishing you all the very best!
