  1. Hi, Is it possible to export animated geometry (Alembic/ OBJ sequence etc) from Houdini Apprentice? Thanks a lot Josh
  2. Hi, I'm trying to find a way to export nested .ass files - for example with a crowd. I can get a crowd exported using alembics using this method - but I was wondering if anyone could point me in the right direction for exporting, say, each agent as an arnold procedural within a single arnold procedural i.e. nested. cheers
  3. Export Quicktime Error

    Hey guys, I'm having a hard time exporting mov files on H17. I can only export avi files and the files are pretty huge. This is the error. Does anyone knows what it could be? Thx Alvaro
  4. Houdini23ds max through Alembic

    Hello, So, first I exported flip tank particles in .abc format then I load that in 3ds max with vray proxy. But how to render them with proper whitewater or ocean shader? It is rendering a blobby mesh in my case. And there is also absence of particles in some frames and some kind of clipping in between. Can someone please guide me in this. Thanks in advance.
  5. Pyro to Maya

    Hey magicians, What's the best pipeline to export pyro to maya? I'm working at houdini scale and I think maya scene is x1000 so I'm worried that the smoke probably will look bad. Any tips will be really appreciated Thanks!
  6. Hi forum. I am trying to export simulated curves from Houdini into Maya using Alembics so they drive the XGen anim curves. I have exported curves from Xgen into Houdini and connected them to the 16.5 Hair System and simulated them. The problem is the Alembics from Houdini are exporting all the curves as shape nodes under one curve, instead of exporting each curve separately. XGen's Anim nodes wont read these. Does anyone know how to export curves from Houdini into Maya with Alembics without them packing?
  7. XML Export Tool

    Hello, I have a python script that saves geometry data to xml (that is later used in the game engine). I would like to make something similar to the ROP FBX Output node to save the xml file (to make it consistent with the other Save to Disk nodes in Houdini). I tried different HDAs/Asset types but they all look the same and they're not exactly like the ROP FBX Output node. (same look, same flags, available in the geometry network view, can't be opened, no outputs). Is there a way to change a HDA to have all those features or do I have to look into HDK? Thank you
  8. Combine clustered pyro into one domain/object to export for render in v-ray Maya? Thanks in advance.
  9. Hello I have an animated Alembic file which I am piping through the instant mesh SOP ( game shelf tools ). How do I export the mesh's state at each frame into separate files ( Obj/Fbx) ?
  10. I would like out to export out a Smoke Trail simulation as a VDB sequence so I can import it in a different package. Because the smoke is clustered I can't figure out how to export it out. It only seems to export out one cluster. Setting $CLUSTER in the Rop Output path doesn't do anything. I think that variable is used if you distribute the sim on different machines. I only have 1 machine. Redshift displays there are multiple density channels and the file size of each frame get larger even though the displayed cluster is empty on further frames. I'm using the Smoke Trail shelf preset as a starting point. Eventually I'd like to simulate a long smoke trail along a moving object. Unfortunately I couldn't find any information about this. I'm using Houdini Indie. Thank you for your time.
  11. Hey Forum! Basic question here: When using Houdini Engine with UE4 - Do we need to manually bake out color maps and other uv maps such as those generated from the erosion tools in houdini (flow, debris etc.) ? I have no problem importing the .otl into unreal via Houdini Engine - but it is not clear how Unreal/Houdini share all the data that exists on my points in houdini… Thanks, Sam
  12. Hi ! I have some problem with export :S I imported alembic file from C4D to Houdini and simulate some props. then, I cached that simulation and export with ROP Alembic Output node. and when I import that abc file at C4D, All textures gone T_T Where Do I have to add Rest position and UV texture nodes ?? It is too difficult to me Help me ! I set up my nodes like this. Imported alembic file -> blast props -> unpack each prop, add rest position and uv texture node -> pack -> simulation(DOPNET) -> file cache -> convert node (If I didn't add this node, Houdini get fatal errors) -> ROP Alembic Output. At the pack level, I added ROP Alembic Output and export it for test. and It works ! but when I finished simulation and cache it, use convert node and ROP Alembic Output nodes. Its Textures are gone T_T How Could I do ?
  13. export camera?

    Hi, I cannot find this anywhere. How do you export a camera from Houdini? Here is what I tried: I created a new geo node, then object merge node, merged the camera then changed transform to into this object. I used a file node then export. When you import it, the camera is there and moves correctly, but when you go to choose camera there is no camera to choose. I tried creating a camera, then changing the defcam.bgeo to my directory, but that did not work either. What do I do? My end goal is to export a camera to another houdini scene and to maya. Thanks
  14. Hi All, In Houdini 16.5 Alembic rop export, the build hierarchy from attribute behave differently now. In the past, I need to pass a proper hierarchy naming ie: /group1/geo1/geo1Shape and all the transforms will be stored in geo1 and loaded as expected in Maya. Now when I do exactly that, this is the hierarchy I got in Maya: /group1/geo1/geo1_instance1/geo1Shape Where all the transforms are stored in geo1_instance1. In a way it's good to catch any shape nodes that is not exported with its parent transform in path attribute. Is there any way to make the old way work? How do I control the "_instance" naming part in path attribute? I would like to output the hierarchy EXACTLY like how I set it up in the first place. Thanks
  15. Export issue

    So I´ve been trying to export my mesh and animation to Marvelous Desinger. It works everything is there, but the size in marvelous is really tiny, which will mess up the simulations since it´s to small. Tried to import it the mesh inside Maya with meter settings and it´s tiny there as well. So, can I tell the fbx to export in meter, or do I need to change the scene size somewhere, even tough Houdini works in meter ?

  17. Hi family i have a geometry that went through a simulation, now in sops i have point position data, how is it possible to export an array of the position data across all frames of a desired point?
  18. Hi all, I want to import a particle simulation from houdini to Maya without using the Houdini engine and render in Redshift. I made a way around it stamping spheres into particles and exporting them as Alembic, but the file is too damn heavy. Do you have any suggestion? Thanks in advance.
  19. Hello, I was wondering if anyone could share the correct workflow for face sets in alembic. Currently I'm importing an alembic from C4D that contains polygon selection sets which are passed through the alembic. When I export the alembic back to C4D, after passing through my rig node tree, the sets are lost. Can anyone shed some light on this?
  20. Hi everyone, I'm attempting to export a pyro sim as VDB files for use in Maya 2017. I've followed a few tutorials but each time my VDBs are only 1KB each in size. Has anyone had experience with this process and could offer some advice? I'll include a copy of my hipnc if someone would like to take a look. Thanks for your time, Kind regards, Chris (AUS) campfire010.hipnc
  21. packed rigid body export to fbx

    Hello, Looking for help on using the game tab RBD to FBX exporter. It should be rather straight forward but Im not sure as to what I should be selecting when its asking for a Node to export. The documentation says it should be a "Reference to a packed object". Is this just the geo node at object level or is this the the rbd packed object in the dop? I get errors no matter what I select. And is there an order to selecting my tab icon first than the object or vice versa? Thanks DoorExplode_OD_v005.hip
  22. Hello all, Newbie calling for help here. Now, more angry and with less hair... I am trying to export out an alembic file that will have my packed fracture in a grouped hierarchy rather then a solid piece of geometry. My end product would be an alembic that I can auto assign bones(via script) to each piece of geo inside of maya. From there I would like to export out as an FBX. My geometry setup in houdini does have an Assemble node with Create Groups, Create name Attribute and create Packed Geometry selected. In my fracture voronoi I have an attribute created called piece. Also in my voronoi tab under groups Ive selected create groups with named prefix, interior and exterior groups. I dont know if Im setting up my tree wrong in my fractured Object (Door) or if my settings to render out with a ROP Alembic are jacked. So my question is 2 fold, Am I setting up my packed fracture correctly to give me individual pieces come alembic time. AND are there special settings/ and or combination of settings of both. Ive read the manual, rumbled through sites and still no bueno. I've included my scene for further diagnoses. ANY help would be greatly appreciated. I've also tried incorporating Laidlaw's RBD/FBX export into my hip and couldn't get it to work. On that note any FBX workflow that can be recomended. I tried the game tab RBD to FBX export but I'm confused as to what node to export I should select in my file. Everything Ive tried so far just throws an error Again I appreciate ur help!

  23. Export Multiple FBX Using Python

    Hey, so I have a situation where i have exported a load of rbd simulations to alembic and i now, after re-importing them back in as alembic archives, I want to export them out from Houdini as FBX. Now, i can do this fine on an individual level, but it takes a while to export each one and then I have to come back and export the next one when thats finished, usually an hour later or something. What i I would prefer to do is to create a python script to automatically export the next one so i can leave them all going over night or something but I dont have any idea how to do this. Can someone please help me out or point me in the right direction? Thanks
  24. Hi Guys I'm trying to export a fractured geometry with two materials, one for the original faces and one for the new faces generated after fracturing. I just can't seem to figure out what sort of attributes I need to have for the FBX exporter in Houdini to include them as two distinct materials. I've tried the material node in various configurations but I just can't seem to get it right.
  25. Hi all I have a question about exporting geometry using .fbx - Basically I want to export certain model that has been created in Houdini and render it in Keyshot, while in Houdini the model looks smoothed as shown in the pic attached sc_from_houdini.png but when i import it in Keyshot it comes totally black opaque and unable to receive new materials. I can overcome this situation by entering dummy (zero) changes to the geometry in Keyshot, which renders it able to receive materials and be rendered properly. Now, the problem I find is that once this first issue is fixed, the result of the render is showing the raw polygons and not a smooth surface as it appeared in the Houdini renders, as we can see on sc_from_keyshot.png attached. Anyone have idea what this happens? Perhaps I am missing some step before exporting the geometry, or exporting it wrongly? Sorry is not the same exact camera, but is the exact same geometry, I also attach here the houdini .fbx exported file ) Thanks in advance ) s.fbx
