  1. The help docs for the Terrains say that "Lidar Import can load LIDAR formats (for example e57) as height fields" but there's no option to convert to a HF that I can find? Am I missing something? http://www.sidefx.com/docs/houdini/model/heightfields.html Thanks, Kevin
  2. LIDAR to Heightfields

    VolumeFromAttrib works pretty well. Thanks Illusionist. I also tried VDB route and tiaingulate2d (which I had forgotten about). VDB required a decent amount of fiddling but did a great job and roughly the same memory / time to process as VFA. Trianglate2D became unhappy after a couple millionish points so I didn't get anywhere with it.
  3. Re number of replies, your question isn't tips and tricks, it broadly covers entire departments and careers of CG artists. Integration is largely the domain of compositors but upstream a small army of people are dedicated to making it happen, from the on-set sup to the texture and materials artist to 3D artist to the compositor. Take a look at The Art and Science of Digital Compositing by Brinkmann and the VES Handbook of Visual Effects by VES. Great references. And there's a British Film Industry Visual Effects Foundations ebook running around that has a concise descriptioin of the skills involved.

    Oh, right, I remember that now, there was a guessing game about what they could be on odforce too I think. Thanks.

    I must have missed a news cycle. Where did you read this?
  6. Anyone have a simple Time Machine node example? i think its a basic time warp but can't get it to work (also, I'm a newbie with Houdini's comp tools).
  7. Time Machine compositing node example?

    Thanks, Mark. I like the tattered effect you achieved. It might make a nice decaying effect. Did you mean first input or second above for the animated sequence? Using an animated noise etc in the second with small frame values works pretty well. Attached an example if anyone needs a starting point. heartOverlayhip.hiplc

    Two buttons on each help page: Typo and Inaccurate, similar to the ❤️ button. You click the button and can highlight the text that is a typo or incorrect. Click the button again and the page submits it to the Docs team, effectively making all of us proofreaders. You could go all out and have a little comment box pop up too. Being too lazy to file a bug report unless things are crashing, I never do for typos or inaccuracies in the docs, which aren’t often in Houdini’s docs, but sometimes things change over versions and a line or two of a doc is made inaccurate, but would if it were just a click or two.

    It feels like the 16.5 drumbeats should have started by now. Or did I miss something at SG this year?
  10. What's kiling my particles?

    Thanks Jinguang, much appreciated.
  11. What's kiling my particles?

    I have a simple curved tube open at the top and closed at the bottom with 3 fluid sources inside (see image below). They emit and the fluid travels nicely inside the curved tube. However, it doesn't collect at the bottom of the tube. It also doesn't appear to be leaking or near the volume boundary (so that's not killing the particles either). Hip file attached. Much appreciated if anyone has time to check it out. workbench.hiplc

    Nice tip. I never found copy stamping to be all that confusing but to be sure, the old for loop subnet business was really strange. The new For Loop blocks are powerful and I'm sure I'll get used to them but using fairly high level labels such as "metadata" and "feedback" to describe "Loop Information" and "Iterate On Top the Result of the Last Loop" might be concise but are so abstract as to be confusing.
  13. Houdini 17 Wishlist

    Re-imagine the For Each Blocks. I find the current language (Meta Import, Feedback, etc) needlessly confusing and the layout (while extremely nice aesthetically) doesn't add clarity, but rather adds a confusing DOPs-like weirdness to the otherwise straight-forward SOPs. Case in point, you set the block paramaters up in the Block End node. And I strongly disagree with the help docs statement that this is less confusion than copy stamping.

    Disable an input to the merge node without disconnecting it.

    Invert the color of the font and background on the current active paramter tab. Paramter tabs that are now in a bold font are helpful but make it hard to tell quickly which tab is the exposed tab.
  16. Pose Library and FBX?

    I'm struggling here too. I create a geometry, rig it with 3 bones, create a subnet and animate it. Then I save the animation as a pose to the pose library and save the subnet out as an HDA. The problem arises when I bring in the HDA and try to apply poses. The poses don't take. Following this thread, I then Allow Editing of Contents for the HDA, dive in, select all the nodes and open the Type Propertes. In the Paramters tab, I get a "Can't edit paramaters for this operator" message? Any chance you guys could do a turorial on using the pose library. Fiona did a great starter but applying the poses to HDA rigs seems to be a black art. Thanks Kevin

  19. Can you open multiple instances of Houdini under an Indie license? I don't think you can but checking in case I've missed it. I know you can fire off a Mantra render from the terminal and keep using Houdini but it would be great to have more than one copy of Houdini available for some projects. Related, is it possible with 2 Indie licenses?
  20. Renderfarms renderers and plugins

    I had a fairly miserable experience with Zync and the opposite with GM. Second what StepbyStep had to say, esp re support. You also can render your Nuke comps which is handy.
  21. Solved. I had a file path mismatch after upgrading to High Sierra. For Indie users: open Houdini Terminal: houdini -indie ~/filepath someHoudiniMagic.hiplc
  22. Thanks Symek. Yes, single computer with Indie license. I'll dig in and see where I'm going sideways.
  23. 16.5 drums

    So there's that. Good one.
  24. 16.5 drums

    Good info. It was the the Houdini History thread below that got me thinking.
