  1. Remap noise color

    Hi. I am trying to remap the colors from a noise node in a COP2 network. What I would like to do is replacing the current colors of the noise with 4-5 colors that I have defined myself. I can't find a way to remap the colors individual.
  2. How can I get the number of connections connected to the input of a switch node with an expression?
  3. 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?
  4. 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?
  5. I was able to get the job done with "UV Texture". Texture type set to "face"
  6. 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.
  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 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.
  10. Getting value of string parm hda

    The function is "parm.rawValue()"...
  11. Hi I am trying to get the value of a string parm, but I can't find the function for this.
  12. 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
  13. 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"
  14. 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.
