  1. Hi Odforce, I was wondering if anyone has knowledge about how to enter your own default values of a created channel within the parameter editor. I want to use a mulitparm block(list), created from a folder type, and add parameters according to the amount of nprims. I want the parameters within this folder multiparm block (list) to have default values/expressions. The idea is to link each channel to an asset with a random so the parameters (see picture) are for each asset different. Not sure if this is good idea or if it could be achieved easier, im open for other ideas. Thanks in advance!
  2. If I have parameters on digital assets that are expressions I sometimes find it useful to have another parameter that shows the result of the expression. I can obviously middle mouse on a parameter to show the evaluated result but is there a way to show the evaluated result by default? I feel like the answer is no so my solution would be to use callbacks for any parameter that affects the expression then update the 'result' parameter as a raw string, unless anyone has a better suggestion?
  3. hello,I would like to use python to move a parameter to a folder. What functions do I need to use? please help me,thanks.
  4. Hi everyone, I have a menu parameter that is filled using a script. The menu looks like this. "token", "Label" "p", "P" "flow", "Flow" In the VEX code I want to get the selected Token of the parameter. int id = chi("attributes"); string name = chs("attributes"); Both of these return the selected item index but not the token or the label. Is there a way to get the token of a menu parameter using VEX? Thx! Christian
  5. Hi guys, I'm trying to create a shelf button that quickly create a parameter into the selected node. To start, I'm happy with the initial solution, taken from https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&t=22539 n = hou.selectedNodes()[0] group = n.parmTemplateGroup() n_fol = hou.ui.readInput("Folder name: ", title=('Add Float:'))[1] n_par = hou.ui.readInput("Parm name: ", title=('Add Float:'))[1] folder = hou.FolderParmTemplate(n_fol, n_fol) folder.addParmTemplate(hou.FloatParmTemplate(n_par, n_par, 1)) group.append(folder) n.setParmTemplateGroup(group) but I have a problem, when I run again to add a second parameter, the folder takes name from the first one adding '_1' instead of taking the name I put in the folder name. The label it's ok, with the name I insert. Any idea why is this happening? Thanks!
  6. Hi. Guys. I got a huge work to do, there is a fbx file export form max,when i import it to houdini, it include too much parameters on Geo interface form max. So i want delete it all since it was useless. I make a sketch show what i want to do. I just want to remove the ss parameter form interface, not just delete the keyframes or expression. If there was something like hou.parm().destory() modules can do this. Thanks.
  7. Hi,guys, I am trying to build a digital asset here,It's a asset inside shader,I mean it's at vex builder level. And now I want there to be some parameter which link to a rotation of an object level camera. Because the rotation keep changing,so I must like write a expression for the parameter of the DA. And here is the problem,it seems that I can't write expression at vex builder level,it does not update. I know I can promote parameter to shader level,but I do want to keep it at my digital asset which is at vex builder level. So,how can I get that changing data and make it work for my digital asset? I did some test,maybe someone can check my test scene(houdini14) and help. Thank you guys. Peng.
  8. Hi! I've created a VEX code that I've wrapped as an OTL digital asset with a nice parameter interface - all based off a VOPSOP. Now I want to add a parameter to the VEX code and have that parameter be part of my nicely arranged parameter interface. However when I added the parameter to the function definition and created an identically named parameter through the type properties interface, the parameter doesn't change the behavior of the code at all. Now when I check the "Get Properties from Vex Code" box, my nice parameter interface disappears and gets substituted with whatever parameter is defined in the Vex code including my new parameter, which alters the behavior of the code the way I'd expect. So how can add a parameter to my VEX code without having to get rid of my custom parameters? Thanks a lot, Nhat
  9. I want changing defaults when I click some shelf icons. python's parameter object has reverting default method, but hasn't set default method. hscript side, I don't know where to dig. please, help.
