Hi!

Maybe I will ask some strange question: do this is possible to start two copies of Houdini under Leopard? Like in Windows? :roll:

Thank you!

If you launch Houdini by typing ‘houdini’ from the shell that is opened by running the Houdini Shell.terminal in the Houdini 9.5.xxx folder in Applications, you can launch as many instances of Houdini as you want.

good to know that !

Thank you, graham, for so quick and helpful answer!
