Hi~I'm a Houdini-beginner.
I have a question.
When I learn houdini's programing(Hscript,Vex,Python).
What programing do i have to study??

just start to use the nodes and try to use some expressions!

when want to manipulate data then you can learn vex just for information vop nodes are on the end vex code:

when you want to export data or you want to customize houdini(production process, automatisation, project handling, custom gui …) then you need python:
http://www.sidefx.com/docs/houdini/hom/_index [sidefx.com]

in the long run you will need to know all three (expression(simple hscript), vex and python). just the most important one will be vex, second python.

thanks….^^
