  1. Hi, I like to separate my hda's into multple child HDA's and use Import Blocks. Any nice way to store presets of the child hda and be able to acces/select them from the parent HDA? Thanks for any insight,
  2. I would actually like to have this functionality on the Attribute Transfer. For instance when you truly want attributes to be transfered based on distance, piece-to-piece, and when the attributes are variable per point/prim for a piece. Gonna send in an RFE.. Edit: "This is not the Attribute Copy I am talking about. But actually transfering attributes that may vary per point, from piece to piece, (pieces that may actually vary in topology also,) based on distance, like the attribute transfer does. The piece/id parameter in any node is always a big win for me. It's the best thing ever. Much faster than a for each piece loop." -RFE (ID# 117904)
  3. Oh, I missed something, I need to name the menu, and use that { type# != colorramp }
  4. How did you come to that syntax? I don't see it in the docs, and also if I type in { type# 0 }, if I click "Accept" and reopen Type Properties after that, it has changed to { type# == 0 } automatically. Of course I would also like to have it such: { type# != 1 } Please help, Many thanks help multiparm.hiplc
  5. I see the issue is mainly on nodes with multiparms, which is precisely the kind of node for which I am writing this script..
  6. Now after trying again the same code, it doesn't give the error anymore, but Houdini just crashes unless I comment-out the parm.setExpression(). Weird. I don't see what I'm doing wrong. This the crash log:
  7. Hi guys, I have this simple script in a Shelf tool: import hou selectednodes = hou.selectedNodes() for selectednode in selectednodes: parms = selectednode.parms() for parm in parms: val = parm.eval() if type(val) is int or type(val) is float: parm.setExpression('ch(chsop("ref_source"') But it gives an error when trying to execute (on the line that it's getting the 'val' variable). return _hou.Parm_eval(self) hou.ObjectWasDeleted: Attempt to access an object that no longer exists in Houdini. Why is this? I have done this sortof stuff before. This is something that is possible right? Thanks in advance.
  8. Hi, I noticed that the Camera OBJ node has a tab with parameters that is editable via the Edit Parameter Interface. Now normally this is not possible with HDA parameters. But these right here act like 'spare parameters'. How do we get this on our own HDA's? Do you guys think SideFX just did create those with the "On Created" Python script in the Scripts tab?
  9. Hi guys, I wish to have a Noise animated so that flows towards its complemented version. Basically so that the value 0.5 will provide a perfect blend between the two. (0.5 is currently just grey in my Mix VOP, in the hip file..), So that you can loop it. Much like happens in this tutorial on 04:03 with the Offset parameter on the noise effect generated by the Trigonometry VOP, but then on noise values already generated, if that is possible. (https://www.youtube.com/watch?v=r2UNkR1ZNrQ) hip file: shift-animate_noise.hiplc I’m quite stuck with figuring this out. I tries ramps, and modulo’s in multiple ways, but I think I’m missing something. Thanks for any tips, Much appreciated.
  10. Ok wonderful, turns out this is not just an Houdini thing but a global thing, import os print os.path.abspath(path)
  11. Hi guys, How do I get a proper path when using the "/../" method? When middleclicking on such a parameter expression as $HIP/../flips/img.jpg it returns this parent_of_hipfolder/hipfolder/../flips/img.jpg (i.e go in, and then go up again) which Houdini seems to be able to read properly. But I want the path like this: parent_of_hipfolder/flips/img.jpg which I could later on use properly with the python os module, to read the data of the file. It doesn't understand the up-one-folder syntax, "/../" Thank you!
  12. Channel Variables and uses?

    Is it possible to get the channel variable from another channel? A function or something whose arguments would look like chanvar("../../geo1/tx", IT)? (i.e. get beginningtime of the current segment from that channel) Thanks.
  13. Went unto SOPs for this. Felt like a bummer but there we do get lot's of control. Beats the hell out of grid warps of 2D apps.
  14. Hi, How can we warp the UV's (by warping a Deform Plane to use in the Deform COP) with points, to have more control over where it goes? (as opposed to using noises) Like puppet-warp, grid-warp, in 2D apps, Thanks for any help,
  15. Point Cloud in VopCop2Filter ?

    I wonder if such a feature, function or script has been published somewhere. Now 6 years later. If anyone knows something, I'd appreciate if you let me know. :-)
