Sample Takes script try

[Hello world]

Hi there,

I am trying to implement the below to execute two takes for reflection and specular passes.But dont know why the takes doesnt seem to take effect,but i dont get any errors and the script is working.Here is the code snippet of what Im trying.

hou.hscript('takeadd -c -p Main spec')
hou.hscript('takeautomode on')
#hou.hscript('takeinclude /obj/ *')
klig1.parm('shadow_type').set('off')
flig1.parm('shadow_type').set('off')
rlig1.parm('shadow_type').set('off')
hou.hscript('takeautomode off')

hou.hscript('takeadd -c -p Main ReflectionPass')
hou.hscript('takeautomode on')
#hou.hscript('takeinclude /obj/ *')
klig1.parm('shadow_type').set('off')
flig1.parm('shadow_type').set('off')
rlig1.parm('shadow_type').set('off')

hou.hscript('takeautomode off')

klig1,flig1,rlig1 are the variables for lights

thank you very much

Weird mixture of python and hscript.

flig1.parm('shadow_type').set('off') <-- This is wrong.

hou.parm('/obj/flig1/shadow_type').set(0) <-- This is right.

flig1 = hou.node('/obj/flig1')

flig1.parm('shadow_type').set(0) <-- This also works.

Hi erik,

Still I am getting some problems.Takes are not working perfectly.Few parameters still remain the same.

[Erik_JE]

Yeah, the Auto Takes don't respond when setting parameters with python. I have no idea why. Maybe you need to explicitly add the parameter to the take as well. Never created takes through scripts before so can't help more.

EDIT: Yeah, you need to do takeinclude first before changing the parameter for it to pick it up.

thank you very much for the reply.

But in my case,the changes are occurring for the only one pass.and for the 2nd or 3rd pass still the parameters remains same even after chnging

#adds a take
hou.hscript('takeadd -c -p Main spec')
#sets to specular take
hou.hscript('takeset spec')
#make  it live
hou.hscript('takeautomode on')
#include all the objects within the path defined
hou.hscript('takeinclude /obj/ *')
#changes
hou.parm('obj/KeyLight1/shadow_type').set(0)
hou.parm('obj/FillLight1/shadow_type').set(0)
hou.parm('obj/RimLight1/shadow_type').set(0)
hou.parm('obj/testshop/mantrasurface/diff_enable').set(0)
hou.parm('obj/testshop/mantrasurface/refl_objs').set(0)


hou.hscript('takeadd -c -p Main ReflectionPass')
hou.hscript('takeset ReflectionPass')
hou.hscript('takeautomode on')
hou.hscript('takeinclude /obj *')
hou.parm('obj/KeyLight1/shadow_type').set(0)
hou.parm('obj/FillLight1/shadow_type').set(0)
hou.parm('obj/RimLight1/shadow_type').set(0)
hou.parm('obj/testshop/mantrasurface/diff_enable').set(0)
hou.parm('obj/testshop/mantrasurface/refl_objs').set(1)
hou.hscript('takeset Main')
