Scripting doubt

[Hello world]

I wrote a script to find the number of lights in the obj level,for every light I want to create a take

//finds the number of lights in the scene and stores in lightsh

if lightsh[0]:

hou.hscript('takeadd -c -p Main lightsh[0]')

say suppose if there is a point light in the scene by name pointlight1

I want to create the take by name pointlight1

but in my case i get lightsh_0_

Please help me out on how to get the name same as that of the name of the light we creat

Thank you.

You need to properly convert your variable value to a string using some sort of string operation such as the following.

This assumes lightsh is list of node names.

hou.hscript('takeadd -c -p Main %s' % lightsh[0])
hou.hscript('takeadd -c -p Main ' + lightsh[0])
hou.hscript('takeadd -c -p Main {0}'.format(lightsh[0]))

Mantra might already be able to do what you're trying to do, that is if you're trying to create a pass of something per light. See the extra image planes, there are options to export variables and then export variables per light. Disregard if that's not what you're trying to do.

Is there any reference or tutorial for exporting light passes in Houdini?
