  1. You can using houdini scripted UIs (selectFile is what you want) https://www.sidefx.com/docs/houdini/hom/hou/ui From the docs: selectFile(start_directory=None, title=None, collapse_sequences=False, file_type=hou.fileType.None, pattern=None, default_value=None, multiple_select=False, image_chooser=False, chooser_mode=hou.fileChooserMode.ReadAndWrite) → str So for example: dialog = hou.ui.selectFile(start_directory=hou.hscriptExpression("$JOB"), title='Select your file', file_type=hou.fileType.Image) You can make start_directory a $VARIABLE or something more explicit like "/my_folder/images/"
  2. Thanks for the response, Mark. It's good to know I'm not being a total plonker!
  3. You could set up a SOP solver in your DOPnet that takes the normals from your emission surface and attribute transfers them onto your particles having converted them into velocities.
  4. Hey all, I've recently installed Linux Mint 18 on to a dual boot on my laptop. I've been running houdini on windows 7 for a while without any problems. On Linux, however, I'm finding that Houdini will crash immediately I wake the laptop from sleeping (i.e. lift the lid up). Any ideas? Houdini 15.5 Apprecntice Thanks
  5. The cheapest and simplest way to do this is to render out spheres or discs with pscale determined by age and a ramp, some random colours for variation and some rotations on them. Render them flat and then slap on some glow/glint in a 2D package like Nuke or AE.
  6. Hello, I'd like to include a 'hide/disable when' conditional on a parameter which is being created by a script. How do I do this? null = hou.node("/obj").createNode("null") null.setName('newNull') tabs = null.parmTemplateGroup() for folder in tabs.entries(): tabs.hideFolder(str(folder.label()), True) null.setParmTemplateGroup(tabs) parmGroup = null.parmTemplateGroup() parmGroup.addParmTemplate(hou.ToggleParmTemplate("overrideToggle", "Override Cache Version", 1)) parmGroup.addParmTemplate(hou.IntParmTemplate("overridingVersion", "Overriding Version", 1)) null.setParmTemplateGroup(parmGroup) null.parm('overrideToggle').set(0) null.parm('overridingVersion').disable(1)
  7. Heya peoples, I'm going round in circles on this one and it might just be down to my poor understanding of python and/or houdini. I've managed to get 90% of what I want for this tool complete but the final piece evades me. I've got a python tempfile.TemporaryFile being created when 456.py is triggered - it works perfectly - i.e. created upon opening a hip and deleted once the hip is closed I think what I want to do is trigger the 456.py from within a shelf tool (which is a custom saver script) I mean this is essentially the age-old quest for an "onSave" callback but sadly I have no understanding of C++ or the HDK so this solution is totally lost on me. Any pointers appreciated Cheers
  8. on the flipfluidobject in the autodop there is a parameter called "particle separation" lower values = less separation = more points
  9. Heya, Is there a way to lock these variables so that they can only be edited via script? i.e. to prevent users going into the Variables dialog and deleting them off.
  10. Heya, I've created a custom menu tool and added it to the menu using the MainMenuCommon.xml file - is there a way of soft-setting a hotkey to it within the xml, i.e. for multiuser project-based deployment? I'm thinking that adding the HotkeyOverrides file might work but if it's possible to keep it all contained in the single xml file that would be far tidier.
  11. Heya sebkaine, Thanks for the nudge. Party on!
  12. Hello, Noob here. I would like to create a character that appears to be made of a viscous liquid with some splashy/blobby bits falling off. I've tried using my emitting geometry as an isooffset SDF and then piped this into a field force dop with some success but it's not very controllable. I've also looked at using pop attract to try and keep the particles closer to the deforming geometry but with little success. Can someone give me a nudge in the right direction as to what methods I could try to implement this kind of effect? Any pointers appreciated Cheers
  13. Did anyone get any further with this? I've tried using vdb sdf as a field force which doesn't work ideally. Any ideas or nudges in the right direction would be appreciated.
