thanks. So answer is yes. It doesn't take additional render time but it's always good to keep real world object scale

Hi there. I'm wondering if PBR is physically correct then it should be obvious to keep a correct object scale. So for example if my model of a bottle is 1x1x1 then it's really huge bottle and PBR do all it's calculations incorrectly and theoretically longer.
Let me know your thoughts guys.

Actually if I set python lib to:
HOUDINI_PYTHON_LIB = /opt/local/Library/Frameworks/Python.framework/Versions/2.6/Python
similar to rvinluan's advice from this thread:
http://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=28933&highlight=HOUDINI_PYTHON_BIN [sidefx.com]
and HOUDINI_PYTHON_VERSION to 2.6 then Houdini doesn't want to start at all
