  1. Linux UI problems

    So this was actually a locale problem. After carefully reading the errors messages, it appears that during the installation (I couldn't find them in the .tar.gz) some files are created using the locale for the formatting, hence problems... For example a UI definition file contained range(0,001,10) instead range(0.001, 10) which is a syntax error in the DSL used in that file, and the rest of the file is dropped.. I'm glad it was nothing, I ordered a proper us-eng keyboard, which is also a great programming tool.
  2. Occasionally, I create objects that are a bit too large. For example, a default heightfield in H16 is 1000x1000 When you drop a camera from the persp view, you can't really move around the scene because the handle of the camera makes it move in increments of a few units with each mouse move. What is the right thing to do in this case ?
  3. Foot planting

    Hi, How to replicate this setup: At 0:37 I don't have the same joints . Where does his QuickRigCharacter joints come from ?
  4. Linux UI problems

    No high DPI display (a good size Iiyama 2560 x 1440 but nothing really special) The driver is the one provided with a Mint package, so this is the manufacturer driver (most recent I could install). I've been using Houdini for a few weeks on Windows on the same computer, but I can't work without a proper shell and Unix tools, so I need to go back to Linux (which I'm using since the late 90's). I'm comfortable with the Houdini UI, I actually like it. I've been using it daily under Windows. I actually have lots of errors in the camera nodes, so this is not an instance of PEBKAC. I left Ubuntu when they switched to Unity and spent some time under OS X but I bought this workstation (HP Z820, dual E5-2670 with 64 GiB of RAM and a NVidia 980 Ti) with the intent to do some rendering on it, preferably with Houdini under Linux.. I will try other distributions tomorrow.
  5. Linux UI problems

    I'm evaluating 15.5 under Linux Mint and there are all sort of problems. Handles by default are incredibly small but this can be changed in Preferences, even though it should be by default at a reasonable size. Cameras won't work. By default it seems to create orthographic ones, but they are impossible to use; it throws a great amount of stack error, (references to near and far planes I believe) FEM doesn't work. it stops at 25% of tetrahedralize step, never to finish. A simple cube should takes a fraction of a second under Windows, so I guess he's stuck in a loop somewhere. Middle mouse button doesn't work. It's doing random things like setting a keyframe, setting nan, random values, and so on. I couldn't even try Mantra because cameras are impossible to set up. Right now I have a feeling Houdini under Linux is so broken. Do you use Linux, and which distribution are you using (assuming you don't have any of the aforementioned problems).
  6. Crowds RBD Ragdoll for 15.5

    Thanks. I wasn't able to open your file properly, but I replicated the nodes upstream and it seems to work.
  7. At 2:11 what's upstream from merge_transitions is missing using the DOP generated by Houdini 15.5. Hence no collisions happen between the ball and each biped. Can someone tell me why this is happening, and how can I fix it ? Is there a more up to date tutorial for 15.5 ? ragdoll zombies.hipnc
  8. Polyextrude along world Y vector

    Hi, I'm modeling a city like object, and I need to make it less flat. Right now this is a grid with several polyextrude nodes. Can you suggest me several methods to have the faces extrude along the world Y vector. The mountain node also changes the normals, so I guess I need to fix some of the normals after that node ? city.hipnc
  9. Non procedurally flatten a curve

    I have created a curve, but I didn't realize some points were created outside of the XZ plane. How can I fix the curve so that I don't have for example, a transform node with scaleY=0 after the curve. I just want to non procedurally alter the points.
  10. Hi, I need to check if Houdini runs correctly under Linux on another partition of the same workstation hard drive. What do I need to do ? Is there a time limit to the apprentice license, can it be renewed ?
  11. Solids interpenetrate at the start of simulation

    Thanks; around a 100+ substeps seem to solve my problems in this scene.
  12. Solids interpenetrate at the start of simulation

    Can you make a file with a simple stack of 50x1x50 boxes stacked on top of each others, that won't fall by itself ? Even with boxes which are much more wide and deep than high, they fall like ice cubes in the wind. When I do that, this fails like that: Also some pieces go right through the ground plane.
  13. Solids interpenetrate at the start of simulation

    There are side effects when I decrease the sleeping time; objects freezing in the air for example. Not sure if it's the right solution, but in some cases the structure looks more stable.
  14. I have a tower of boxes, tightly on top of each others. At the start of the simulation, boxes start to interpenetrate slightly, then when another object hits it, it releases a a spring. What is happening and how can I fix it ? tower.hipnc Here you can see the problem to the bottom left. The tower eventually leans to it left and falls.
  15. Hi, I'm looking for a way to play image sequences from a windows shell. I have mplayer installed, the mf:// selector works when invoked with mencoder, but I can't find a way to "mplayer mf://*.png" an image sequence; there are no error messages, not sure if it's a character escaping problem, or if the feature is not supported under Windows. Can you recommend a version of mplayer which works for this purpose, or any other method in command line ?
