Are key-framed channels supported?
I've animated some digital asset parameters, and would expect to see a animation curve with key-frames connected when i load the asset in Maya.
Granted not all the tangent types could be supported…

I understand that cleaning them up for export purposes is good form - but do the attributes really slow things down or just consume more ram?

Use FBX or alembic export from maya. Do the same back from houdini. I'm not sure about the extent of particle support in Alembic - FBX may be your best bet. Volume support is probably non-existant. However geometry is well supported.

I really dig the forward and back buttons for jumping around networks. I would really dig it if there was a back and forward navigation for the currently selected nodes.
So I started crawling through the preferences and I see /Houdini/Panes/Geometry Viewers/Move to First Operation is bound to Home key. I wanted to test it out but it doesn't do anything for me. Neither does the End key. I'm not sure this is the keyboard shortcut I'm looking for anyway…
Does anyone know if there a hotkey for pushing and popping the selected node?

You don't connect to time like Maya, you need to use an expression.
'$FF' is the same as Maya's outTime.

Houdini Indie and Apprentice » how to get the profile of a section cutting through geometry

Oh sorry, was confused by your pictures. You can do this easy.
Add a fuse sop to the end of the chain.
Then use a divide sop with ‘remove shared edges’.
Or perhaps, group geometry sop, set ‘entity’ to ‘edges’ and on the edges tab - check unshared edges. Be sure to uncheck ‘enable’ on the Number tab.

Technical Discussion » Tracking down load warnings?
- pinkwerks

I happened to close the dialog window that displays load warnings when I open a file (because of say, bad parameter references) - is there a place I can query those load warnings from python? Or perhaps, are those errors logged to somewhere?
Ultimatly I'd like to build an interface to help jump to those nodes and paramaters that are in error so I can fix them. It would be mildly helpful if you could select the text in the open dialog so you could at least cut and paste your way there. Smells like RFE.

In ROPs at least, ‘Pre-Render Script’ is your friend. Make a Geometry ROP, set the expression type to python then copy pasta this:
import os
path = os.path.dirname(hou.parm('sopoutput').eval())
if not os.path.exists(path):
os.makedirs(path)
Optionally, you can then click on the gear icon and ‘Save as permanant defaults’ - now everytime you create a Geometry ROP you will get a bit of code that makes sure your ‘sopoutput’ (Output File) generates a valid directory. Of course you can tweak the above script to death but it's functional.
For instance, you could substitute ‘sopoutput’ for ‘soho_diskfile’ if this was a Mantra ROP…

Something closer to this? You weren't setting the value before, you were just getting it with eval(). Also, you have to test on type().name().
selNodes = hou.selectedNodes()
for i in selNodes:
for j in i.allSubChildren():
if j.type().name() == ‘geo’ and j.parm('vm_matte') != None:
j.parm('vm_matte').set(1)
selNodes = hou.selectedNodes()
for i in selNodes:
for j in i.allSubChildren():
if j.type().name() == ‘geo’ and j.parm('vm_matte') != None:
j.parm('vm_matte').set(1)

Try looking at pcopen and pcfilter. They will look-up a point cloud, and give you what you're after. Here is some info on that:

Try attached, 2 methods.
The first uses fetch. Not sure if it still will inherit the camera scale?
Second is camera that uses rivet, but requires you to add some sop's inside cam scaled.
If these don't work, you may have to write some ugly expression in the T & R attributes. Someone with more expression function knowledge would have to help you there.
Check this if it comes to that:

A trick around this situation is to constrain (pin, rivet, whatever) a new render camera to the position of the scaled camera.
Indeed scaled cameras screw up almost every 3D package that I've used.
