  1. Hey guys. Is there any way to sync selections between multiple viewports such as perspective view and UV view so I can see my selections in multiple places? Here's how modo (and any other normal 3D software) shows selections: And here is Houdini which treats different viewport independently which I'm sure has some logical explanation but when I do UVs I'd like to see my selections vica-versa in all the viewports. Is there any way to do what modo does folks? Please help me! I don't want to abandon Houdini and roundtrip to another app to create and modify my UVs. Thanks in advance! Kristof
  2. Hello community! In my viewport, i see blue lines for every group i have. (see on added screenshot). It can be is quite annoying with complex geos, so how can I turn this off? Im on linux mint, H16 btw Thanks for reading/helping.
  3. Heya, Anyone had issues with the viewport display of the "Hair Generate" node? Thought I'd lost a load of work to find that it no longer displays unless viewing wireframe mode.
  4. Houdini's hairgen node displays the hair polygon lines with thickness defined by the width point attribute. How can I visualise this in the viewport on normal curves/polygon lines?
  5. I have four visible platonic objects in the viewport here in this scene, but wehn i display the information on the end loop ive got 48? how can i split them or randomize there position? Lines_001.hip
  6. Hello, I am working on a prerendered 360 VR video with Houdini. We are currently builing our pipeline for this and want to implement a feature that allows to connect the Houdini viewport to an HMD like the Oculus Rift or HTC Vive. Realtime playback speeds are not necessarily that important. Does anybody have an idea if this is possible and if how to approach it? Also for proper realtime playback, we want to able to create 360 latlong Flipbooks. The opengl ROP currently does not seem to support this. Any ideas on that? Thanks a lot Adrian FX TD @ Animation Institute - Filmakademie Baden-Württemberg

  8. Hi all, I have texture path set as an primitive attribute and I'm trying to find a way to view this texture in the viewport. It's works great in the render material but I've looked at the insides of UV Quick Shade but I still can't find where this attribute could be imported so that the viewport is affected. Any ideas on how I could get the viewport to render the texture set in a primitive attribute? Thanks in advance.
  9. Hello there, I was able to do constant materials with alpha to use as our background (matte paint). When rendering everything is working as supposed. But I would like to see it in Houdini viewport aswell. Any tips on this are welcome Cheers,
  10. I'm trying to create a shelf tool that needs to select a single primitive in the scene. If I activate my shelf tool while I'm already in primitive selection mode, it works, but I'd like to force the selection method to use primitive selection. I've tried looking at the documentation for sceneViewer: http://www.sidefx.com/docs/houdini/hom/hou/SceneViewer.html I think the key might be the setPickGeometryType function, but the documentation doesn't have a good indication of what I should feed it. Has anyone worked with these view options before? Any help is much appreciated
  11. Get point near the mouse cursor

    Hi. I want to find closest point to mouse pointer. It's not a problem when the mouse pointer intersects with a surface. But how to get the point if it is outside the surface? I have the pointer origin and direction https://s9.postimg.org/a8y8r58i7/image.png
  12. Hi everyone, I'm a bit confused right now because I have a weird issue on my Houdini when I work on Alembic. I have some huge (not that huge, but still) models in Alembic format and I want to do VFX stuff on it. But I can't have a proper feedback on my viewport when I do some operations on it. As you can see on the gif capture, the color does not appear in the viewport, but if I save the scene, and open it again, the color appears. I checked my graphic cards driver (I have a GTX 970), and everything's on date, and I'm on Houdini 16.0.621. Is there a solution ? Thanks in advance, Gael. EDIT : Even if I launch Houdini as Administrator, the bug still appears. I need help :<
  13. Hi, Not sure what is going on here, but if you create a dopnet inside a geometry node, scene lights wont affect pyro in the viewport. If you back out of the dopnet, then you can see the light affecting pyro. However, if your dopnet is at object level lights will affect pyro. Why can't my dopnet be inside a geometry node and have the scene lights affect pyro so I can see whats going on? Photo 1 is inside the dop net. Phpto 2 is inside the geometry node but outside the dopnet. Thanks smoketho.hipnc
  14. I'm in the middle of making an otl for our artists and was wondering if there is a way to switch Houdini's viewport panes between Scene View and Composite View. I haven't found the proper help files for manipulating Houdini's layout through scripting. Thanks Mike

  16. In Houdini, is there a way to show some custom values as a HUD-type display in the screenspace of the viewport (any viewport, not necessarily cam viewports)? I mean something similar to the framerate display (Display Options->Guides->Additional Info->Show Time) but for custom values.
  17. Hi guys, I was wondering if it is there any way to change certain object's parameters depending on whether I'm inside of a subnet or not. Basically my problem is that I have a rendering subnet hda, which allows me to only render stuff that is inside, or referenced inside my subnet. But the issue is that if I have multiple subnets in my network with multiple lights in them, every light is visible in the viewport, making it hard to work with lights, since everything is visible and added together making the entire screen look blown out. I know I can disable the "Enable in Viewport" checkbox on my lights manually, but it would be awesome if it would be possible to only enable that checkbox on my lights when I'm actually inside my subnet and disable them when I go out from it automatically. In case anyone has any ideas on how to achieve this, I would appreciate if someone could nudge me in the right direction. Thanks in advance for any help! Best, Laszlo
  18. Viewport Changed Python

    Heya, I've written a little python expression to scale geo dependent on through which camera is being viewed. It works but does not recognise when the viewport has changed - is there an event trigger I can use to get it to recognise this change? import hou desktop = hou.ui.curDesktop() scene_viewer = desktop.paneTabOfType(hou.paneTabType.SceneViewer) viewport = scene_viewer.curViewport() camera = hou.GeometryViewport.camera(viewport) if 'preview' in str(camera): return 0.01 print 'preview cam' else: return 1
  19. Does anyone know whether or not a fisheye projection is possible to write for the viewport? I'm looking around on behalf of a friend, and I think it might be possible, from perusing the HDK, but can't tell for sure. If anyone knows whether this is possible or impossible, either way, it'd be great to know. Thanks!
  20. Hey, I am trying to do some stuff in python with viewport selections. I want to query whether or not the user has anything selected, not necessarily get what is already selected. As far as I can tell the only way to do anything with the viewport is through toolutils. If I use "toolutils.sceneViewer().selectGeometry()" and nothing is selected, it waits until the user hits enter over the viewport before continuing. Is there any way to simply return whether or not any geometry has been selected without having to wait for the user to hit enter? import toolutils sv = toolutils.sceneViewer() geo = sv.selectGeometry() if geo: print "There is a selection" else: print "No geo selected" Thanks!

  21. Guys, I guess it might be a veeery silly question but I just can't do it. How do I display textures on viewport? In this case I have this ramp applied (not an image texture) Thx! Alvaro
  22. VR flipbook

    Hey guys, I'm working on something for VR and every time I want to preview something on the oculus I need to make a low res render because flipbook doesn't give you a 360 view. I found somewhere a example of someone making a 360 flipbook (can't find it anymore) but haven't been able to figure out how to do that. Any ideas?
  23. Hi! I'm really new in houdini so probably this is a noob question: I have some outlines that are the outcome of some carve operations. When I animate the alpha from 0<Alpha<=1 everything goes as expected BUT in any frame that the value of alpha equals 0 I can see the outlines in bright color (the one that you could previously set). I don't know if this is only a viewport thing (I think it is) maybe some viewport feature or something like that because I'm following a tutorial and in the video setting the alpha as "0" makes them totally transparent. Hope that you can understand what I'm saying, my english is not that good. Thanks!
  24. Pyro ViewPort Issue

    Hey guys, so had this odd viewport issue for a while with pyro - sometimes it will show it properly (with shadows lighting etc.) sometimes it will be solid white voxels and then other times black smoke with again no shadows - provided screenshots below to help! I thought it maybe a GPU problem - running a GTX 770 - i7 3.3ghz - 32gb ram - Turning headlight only on in viewport (lightwise) then clicking back to normal lighting sometimes fixes it but not always (Images below show the black and white viewport errors i was on about) rather than shaded white smoke
