Hi folks, my pipeline is Maya > Houdini> Maya
I am a bit confused about scene scale.
Please help me! Thanks in advance.
These question are bogging me down::

1. How much percent should I scale my objects in Maya to simulate properly in Houdini space?
2. If a real building is lets assume 260 meter high then what should be uniform size of it in maya and in houdini?
3. If I want to make some ocean sim what should be the size of the ship and the tank?

4. How can I understand this facts? Please give me some book/reference/tut if you can.

Thanks for your reply!

this path can talk around this, Houdini has default settings 1meter-1kg for dynamics if i remember. You can use houdini tool plugin for maya for switch & test scales.

Thanks a ton for the suggestion!

wow

Houdini > 1 unit = 1 meter
Maya > 1 unit = 1 centimeter

if your object in Maya is 180 units tall in Y (6 foot man)
then to send this model to Houdini you can do one of the following:
in Maya - scale the object UP by 100, then export
or
in Houdini - import the object and scale DOWN by 100 (x 0.01)

this will result in an object that is 1.8 units tall in Y - (1.8 meters)

then to go back to Maya do the reverse
in Houdini - scale the object UP by 100
or
in Maya - import the object and scale DOWN by 100

Thanks for such a simple explanation..

Also keep in mind to avoid scaling cameras ( especially when rendering volumes ), as this can give you very unexpected / wrong results.

indeed!
NEVER scale cameras (or lights for that matter)
