kleer001 Posted August 21, 2013 Share Posted August 21, 2013 I keep getting weird read errors from this alembic file (I got it to mostly work and I'm talking to support, so don't worry). I'm old and crotchety and suspicious and superstitious, and this reminds me of several instances of being in a pipeline and converting published geometry to native geo in Maya to get it to work.... anyhow... How can I take an animated Camera from an imported Alembic file and bake it out to a Houdini native camera? Baking out the geometry is easy enough, but if I bake out the geo from the camera I only get the nice two-reel icon of the camera, not the actual camera object. I'm sure Alembic works just fine for most of all y'all, touch wood, but if anyone has a clue I can borrow I'd appreciate it as I'm fresh out. I'm attaching the abc file I'm working with as a zip because the attacher here doesn't like .abc files, fwiw. track_03.zip Quote Link to comment Share on other sites More sharing options...
Guest tar Posted August 21, 2013 Share Posted August 21, 2013 if the abc doesn't work you might be able to export the SynthTrack as a Houdini Camera Clip. Quote Link to comment Share on other sites More sharing options...
jkunz07 Posted August 21, 2013 Share Posted August 21, 2013 Using CHOPs I was able to create an object node and point that at the abc camera, then I created a houdini cam and referenced the object CHOP. ReadCameraXformInCHOPs.hip 1 Quote Link to comment Share on other sites More sharing options...
kleer001 Posted August 22, 2013 Author Share Posted August 22, 2013 Thank you John. Maybe I used your file wrong. Can you upload a hip with the successful conversion and baking in it? (see my original post for the compressed abc file) Because when I looked there was no explicit translation and rotation in the alembic camera for the CHOPs to use, it was all referenced.

jkunz07 Posted August 22, 2013 Share Posted August 22, 2013 Yeah, here's the baked camera ReadCameraXformInCHOPs__baked.hip Quote Link to comment Share on other sites More sharing options...
kleer001 Posted August 23, 2013 Author Share Posted August 23, 2013 (edited) Haha, you're a laugh riot John. Thanks for giving me a giggle. But seriously, keep your day job. (locking an OP is not baking and the cameras don't even match) Jokes on me though, there's no easy way to get the location information from Alembic. I've got an RFE with Sidefx, so maybe there will be a real solution sometime soon. I'll post here when it come. In the meantime I found I got far less errors and crashes when I put the .abc file on my local disk instead of on the network.

The locked CHOP contains the cameras animation channels for the time range (1-240). Maybe the workflow is described better here: http://www.toadstorm.com/blog/?p=267 Quote Link to comment Share on other sites More sharing options...
kleer001 Posted August 24, 2013 Author Share Posted August 24, 2013 Well that's kind of rude. Holy smokes, my bad, sorry. Please please forgive me. I kinda stressed myself out today at trying to light in a lut (dummy) and totally forgot that the full range of a CHOP animation is saved in a locked node. Whoa, too much time there in SOPs land. Still though the camera you got and the imported one don't like up for me. Doesn't matter though. Gah, I'm such a bore and an idiot sometimes.

Guest tar Posted August 24, 2013 Share Posted August 24, 2013 Fwiw, the abc file imports into Nuke flawlessly. If you import the camera seperateraly into Houdini it's spun around in the wrong direction. Quote Link to comment Share on other sites More sharing options...

I love Alembic, but it's still in the early stages and kinda buggy. Workable, but not perfect. Quote Link to comment Share on other sites More sharing options...
Guest tar Posted November 19, 2013 Share Posted November 19, 2013 bump - looks like this imports into H13 now. Quote Link to comment Share on other sites More sharing options...
