Hello,

Regarding: http://vimeo.com/15198448 [vimeo.com]

I'm having difficulties with the cornell.hip lesson.
Specifically, that no photon bounces are occuring.

When I open the cornell.hip>go to “render view” tab>use “/out/pbr”:

only direct light is in the scene, no indirect.

Houdini Console Error reads:
SyntaxError: ('EOL while scanning string literal', ('<stdin>', 1, 313, ‘import os;os.unlink(“CDVDs/SideFX/SideFX_Houdini_11_Masterclass/h11_mantra_sample_files/indirectlight1.pmap);os.rename(CDVDs/SideFX/SideFX_Houdini_11_Masterclass/h11_mantra_sample_files/indirectlight1-prefilter.pmap”, "CDVDs/SideFX/SideFX_Houdini_11_Masterclass/h11_mantra_sample_files/indirectlight1.pmap)\’'))


anyone know WHY this is occuring? :roll:

I am no expert but you can try to increase the Diffuse Limit on the PBR sub-tab of the Properties tab in the parameter editor to have a value of at least 1.

That's how I always use global illumination.
