  1. Thanks for the reply. There are no odd naming conventions happening, no spaces, usually use underscores or go with camelCase. Now all is working after changing the HOUDINI_ACCESS_METHOD to be equal to 2, but still unclear as to why other data like hip's and bgeo's worked before changing the variable.
  2. Well I was able to find some info about an environment variable named HOUDINI_ACCESS_METHOD and a suggestion in another thread about setting it to a value of 1 (0 by default). That did not fix the alembic or fbx load problems, but setting it to a value of 2 did. This is on a windows system. Can anyone shed some light as to why hip files and sim data and rendered images(exr's) would all read and write fine to the NAS drive with that variable set to a default of 0, but fbx and abc data was not able to read/write correctly.? Does Houdini somehow write those two file types out with different permissions or something.? Thanks for any info. E
  3. So I have an odd problem I haven't been able to figure out yet. I have a Synology DS716+II NAS raid and using it as a shared drive so I can use HQueue to render jobs on other machines. That all works fine to render on the farm, however when I write alembic data to the NAS, I get an error everytime I try to read it back into Houdini or into maya. If I write the exact same alembic data to a local drive on my computer, then there are no read errors. And this seems to only happen with alembic and fbx data. I can write hip files and bgeo's all day to the network drive and everything reads fine, just alembic and fbx data that fails when trying to read it back from the Network drive. Does this make sense to anyone.? I would think if this was a firewall problem or permissions type thing, then no data should read or write to the NAS. The exact error I get when trying to read alembic data back into Houdini from the network drive is "Error evaluating alembic file". ANy help would be appreciated. Thanks E
  4. Well, after more searching, I still haven't found anything. The best I could come up with is writing out .ass files, then in the shell using some bash scripting like this : for NUM in `seq -f "%04g" 1 24`; do ./kick -i /Volumes/vfx/projects/test/shots/test/houdini/arnold1/arnold_ass_render_test_v01.$NUM.ass -dw -dp; done this renders out a 24 frame sequence in the "background". Couldn't find any info or settings in the kick help to set a frame range. Anyone else have a simpler way.? I have never tried rendering arnold through houdini till a few days ago and I would think there would be an easier way to just launch a render in the background. There is probably a node or button within houdini that I overlooked, either way, at least I got to learn some bash.!
  5. Trying out Arnold for the first time in Houdini and can't seem to find a way to render in the background.? The only button on the Arnold node is "Render to disk". I've searched the Arnold docs, and this forum and can't find anything relating to this. Anyone know how to get the same functionality as in the mantra render node that has the "Render to disk in Background" button.? I'm sure it's something simple, but can't find a button anywhere on the Arnold node to allow this. Thanks for any info E.
  6. Ah cool, that worked. Doing the merging of the isoOffset 3 times onto itself and adding the name node in my setup made it do what I was hoping for. Thanks for the info
  7. This could be a simple fix or a dumb question but I just started trying to learn houdini about 5 days ago so I'm lost and new to the package. I did the tutorial on the sidefx site with the volcano demonstration to show how to use the pyro tool preset and really liked how you could make a custom velocity field out of a box and converting it into a volume and doing some vex in the volume sop. So I wanted to experiment and try creating a custom vel field but out of a more interesting shaped volume. I made some sort of corkscrew looking geo and used an IsoOffset to create the volume but this is where the setup breaks. I know when I converted the box to a volume using the volume sop I changed the rank to a vector and I dont know how or where this option is when you convert a surface using the iso offset sop.?? When I middle click on the isoOffset, I see there is just one volume being output and when i middle click the volume sop it has 3 volumes listed. I Think this is where my problem is but again been using houdini a week and have no idea if this is the reason or not. When I plug the volume that is created by the volume Vop into the chain I get the nice curl noise showing up and when i swap it to the volume generated by the isoOffset then its just straight lines which would make sense i guess if it only is a scalar volume field. So Is there any way to convert the isoOffset volume to have a "rank" of vector.?? Or is there an entirely different/easier/correct way to make a custom velocity field that is a shape more complex than a simple box or sphere.? I'm trying to make the switch from Maya to Houdini but being a 13+ year user of maya it's VERY different from what Im use to working with. However the power in Houdini already is making me wish I made the switch a long time ago.! Thanks for any help/info.. E
