Importing `houdini.env` into the shell Aug. 13, 2020, 7:50 a.m.
You can set variables from a bash script if you just source it. But the houdini.env file doesn't exactly contain shell commands.
In bash you could do something like this:
grep -v “#” just filters out comment lines
grep “=” filters for lines actually containing an assigment
xargs -L1 echo export just prints each line with “export” prepended.
So you get output like
export HOUDINI_NO_SPLASH=1
Wrapping the whole command in $() will execute the whole thing as a shell command.
Bash also requires that there's no space around the =. Just make sure of that in your file, I didn't take care of that in the one-liner.

How can I retrieve the length of a curve? Aug. 13, 2020, 7:33 a.m.
The easiest way would be the Measure SOP set to “Perimeter”.

Hi Fabio,
thanks for sending more details, that's very useful. I also see an influx of experienced artists now and more and more studios picking up the tools, which is great.
Good to hear you were able to get good performance with VEX as well.
I might start with a normal direction threshold as well. After all we already have that in Hair Generate! I also found that our geodesic distance methods aren't quite ready for this use case, hopefully we can take that a bit further in the not too distance future.
Cheers,
Kai
