Accessing preloaded python modules in an expression


Recommended Posts

After a bit of light testing it seems that if I import a Python module when loading Houdini, using pythonrc.py, I cannot later use it directly in a parameter expression.   Instead I have to import it into the expression again, which could make the expression string more complicated and error-prone (multiple lines or semicolons).

Is this really the case?  I feel like I must not be doing something correctly.

Additionally, to use random modules in one-liners, sometimes I like to use the __import__ function, like this:


Still makes your expression longer, but at least it's a single line.
