Hi.

I cannot find how to export to fbx some nodes with python. Is it possible to do in Houdini. I have Indie version.

I only found fbx importing through python: https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=16206&highlight=&sid=0e48aeb092269469b0504485d319a8ca [sidefx.com]

Have you tried the saveToFile () method passing a filename with the .FBX extension?


node.geometry().saveToFile(file_name)

Thanks for the reply. I created a sphere object and tried this code:
hou.node('/obj/sphere_object1/sphere1').saveToFile('$HOME/Documents/Exchange/exchange.fbx')

But i got exception:
>>> hou.node('/obj/sphere_object1/sphere1').saveToFile('$HOME/Documents/Exchange/exchange.fbx')
Traceback (most recent call last):
File “<console>”, line 1, in <module>
AttributeError: ‘SopNode’ object has no attribute ‘saveToFile’

Adding geometry() like:

hou.node('/obj/sphere_object1/sphere1').geometry().saveToFile('$HOME/Documents/Exchange/exchange.fbx')


should fix this

Thanks for the answer. The exporter cannot export to fbx. Only obj/dxf/lwo.

And I cannot export a scene with hierarchy to fbx with python. I'll write to SESI for a feature request.

There is ‘filmboxfbx’ node at ‘out’ context. You can export to fbx normally.

You can always wrap the fbx node into a python script:

# create a temporary ROP node
fbx_rop = hou.node('/out').createNode('filmboxfbx')

# set the output path to whereever you want the file to go
fbx_rop.parm('sopoutput').set(“$TEMP/out.fbx”)

# Path to object hierarchy you want to export
obj_path = hou.node('/obj/geo1').path()
fbx_rop.parm('startnode').set(obj_path)

# Now just run the “render” method on the node, and delete the ROP
fbx_rop.render()
fbx_rop.destroy()
