  1. Hi I had a quick look at LOP's and the USD workflow, but I can't figure out if it's "worth" to implement in my workflow. I really like to have things in system and love optimization, but I am only doing relative small jobs and never working on teams. maybe someone can make it clearer when it will make sense to use LOP's and USD in a Houdini context?
  2. How can I get the number of connections connected to the input of a switch node with an expression?
  3. Hi I have 100 different textures in a folder (tex_00.jpg to tex_99.jpg). I would like to create a Redshift material where the diffuse channel is controlled by a texture (RS_Texture) where the texture path is randomized to choose between the 100 textures on disk so that I can have 100 objects with random textures. Is it possible to send some data from SOP to the Redshift material, like ptnum, that can be used as a seed for a rand function to choose the texture? Any ideas how this could be done?
  4. I was able to get the job done with "UV Texture". Texture type set to "face"
  5. Hi guys How can I create UV's on any surface of a model, that is always projected perpendicular onto the surface? Would be great if scale and scale ratio between U and V was constant in relation to world scale, to get the same size pattern on every face and no stretch.
  6. Hi guys. Is there a way to scale mesh "uniformly" like we can do with the peak node, but choose the axis. An example could be a flat long box that we wanna scale "uniformly" in the X and Z axis but not in the Y axis.
  7. Hi @anim I don't know what to think anymore To be clear. I am trying to make a simple table with 6 legs. I am placing the legs by "shrinking" the underside of the table and using the side points to copy the legs on to. The solution I posted before does not work, because I have two points in the middle of the table that will scale wrong, so I made a pretty ugly solution with a fit function. It seems to be a very simple task to do, so I am sure that there is a more elegant way? Here's an example of my ugly solution. table_example.hip
  8. So I came up with this. vector dir = normalize(-@P); vector size = getbbox_size(0); @P = (@P - (dir / size) * chf("distance")); Don't know if there is a node to do this, but I couldn't find it. Cheers
  9. Hi I am trying to get the value of a string parm, but I can't find the function for this.
  10. Getting value of string parm hda

    The function is "parm.rawValue()"...
  11. Repel force field on RBD

    I am trying to create a force field around RBD objects so they will repel each other if they get to close, to avoid direct contact. I have tried to create a metaball force field around the objects, and feed the metaball the objects position so that the metaball force field always is around the object, but the sim breaks. In the example I am only using a single force field for simplicity, but every object should have it's own (See illustration) Am I missing something? or is this approach not suited? rbd_repel_force.hipnc
  12. Is it possible to change the restlength constraint in only one direction in a Vellum setup? It would be great for something like a rubber band that we want to tighten around an object without making it "thinner"
  13. How can I get detailed fluid like this: (Image from Zigor, instagram) I have tried increasing the particle separation but I am not getting that fine geometry. There are "indentations" in my surface, and the "strings" are either lumpy or deleted in the conversion to geometry.
  14. Is the surfsect node just a shortcut for a boolean function, or does it have some unique properties, that can't be done with a boolean node?
  15. When remeshing a grid, from a high to a lower resolution, the edge points are kept. Is it possible to remesh a grid, including the edge points? Original high res grid Remesh original high res grid What I would like to achieve
  16. Hi. After we install a HDA like this hou.hda.installFile('hda_path.hda') how is it possible to get the hda's operator name, so we can "create" it? The installFile function does not return anything... hou.node("/obj").createNode("???")
  17. Import hda/otl with python

    Hi Is it possible to "import" an HDA from disk, via python? and how? Much like we can "Import" example assets from the documentation.
  18. Nuke vs COPs

    Hi. Is COP's a realistic alternative to NUKE, in case of color grading, and editing passes? Is it possible to create the same quality of output in about the same time, if the artist have about the same hours of learning NUKE vs COP'S (If the artist already know Houdini's others operator levels)
  19. Nuke vs COPs

    I was digging around and found "Natron", which seems to have the functionalities I need, and it's open source <3 Thanks for your replies
  20. Hi. Is is possible to create a new "shelf tool set", and move it around? For example to a floating panel, or a bottom panel, if we are using a quad/2x2 layout?
  21. Nuke vs COPs

    @malexanderThank you
  22. Hi everybody. I am trying to get my head around the crazy world of DOP's I can't quite figure out how to reference different object data across the network. I have a pyro/FEM setup where I am using the velocity from the smoke as drag for the FEM solver. When I dive down the "Fem Solid Object" I can see that it's done by applying "Apply data" to the object with "Drag properties" I am then trying to mirror that setup with the vellum setup, but it just doesn't work. My question is, how can I get the vellum setup to work, so that I can use the velocity from the smoke object and also, how does the FEM system know where the velocity comes from. In the "External velocity field" in the "FEM Solid Object" it's just referenced as "vel" but is it referencing all data called "vel" in the DOP? All the best velocity_from_pyro.hipnc
  23. I have 3 entries in a wedge (each 48 frames) that I would like to render out in 3 different videos, instead of render all iterations out in one video. How can I do that?
