Hi All, Can a node store the sub-component selection of it but the node is not shown at the scene viewer ( but for example selected at the network editor ). And how can I get it ? G

That is it. Thanks !

Thanks, but i think it's not what i needed. If I set an python expression on a parameter how can I get the owner parameter ( parameter object, and its name in my case ) , like this hou.pwd() but in my case as a parameter. G

Hi, How can i get the actual parameter name ( or the parameter object ) from a parameter when using python expression on it. I mean something like this: hou.parm('.').name() but not works. In an object hou.pwd() but i need It on a parameter. THX! G

Hi, I need to replace the interface of the houdini rop network with my own panel. I use it for sending renders to farm etc. I use the 'oppresetload' to load my property page to the node itself. The issues come when i want to change a few thing on the interface by a python script ( parameter labels and script callback of buttons -> see script bellow ). The issues are: folder conditional strings are cleared, some parameter type changes ( button strip ). My question is: What is the proper way of replacing a node's interface without Digital Asset ? THX! G Label change: ptg = parm_obj.parmTemplateGroup() parmname = 'active' pt = ptg.find( parmname) if is_sim == '1': rop.parm('issimtoggle').set(1) # pt.setLabel('Active / [ SIM ] / '+self.version) elif is_sim == '0': rop.parm('issimtoggle').set(0) # pt.setLabel('Active / [ RENDER ] / '+self.version) ptg.replace( parmname, pt) parm_obj.setParmTemplateGroup(ptg) button Callback change Script : parm_obj = rop ptg = parm_obj.parmTemplateGroup() pt = ptg.find( parm) pt.setScriptCallback( script) pt.setScriptCallbackLanguage(hou.scriptLanguage.Python) ptg.replace( parm, pt) parm_obj.setParmTemplateGroup(ptg)

THX , but sadly not. These lines clearing the conditional string: ptg = parm_obj.parmTemplateGroup() parmname = 'active' pt = ptg.find( parmname) ptg.replace( parmname, pt) parm_obj.setParmTemplateGroup(ptg) It seems like a bug. Isn't it ?

Hi, I have a simple problem with this python code ( part of a larger script ). It creates a rop network, opens a stored preset for it. And changes a parameter label. It works. What is wrong that the script clears the conditional string of the rop network. Does anyone has an idea ? Thanks in advance ! G The script : rop = hou.node('/obj').createNode('ropnet') drop_preset_name = 'dROP2' op_path = rop.path() cmd = 'oppresetload %s "%s"' % (op_path, drop_preset_name) hou.hscript(cmd) # set the active toggle label as sim and as render , with version is_sim = rop.userData( 'is_sim') parm_obj = rop ptg = parm_obj.parmTemplateGroup() parmname = 'active' pt = ptg.find( parmname) if is_sim == '1': rop.parm('issimtoggle').set(1) pt.setLabel('Active / [ SIM ] / '+self.version) elif is_sim == '0': rop.parm('issimtoggle').set(0) pt.setLabel('Active / [ RENDER ] / '+self.version) ptg.replace( parmname, pt) parm_obj.setParmTemplateGroup(ptg)

Hi, How can I set conditional string ( hide when ) on folder parameter by python ? Thanks G

So there is no way to set the render view to render a specified mantra node by python ? Is it sure ?

If not. Can the render view content determined by python script ( which mantra node is shown ) ?

Hi, Can it be available to check a node is dragged to render view and then specify which node is rendered on it ? THX G

Sorry it was an easy thing about path issues.. Closed.

Hi, I would use mantra Pre-Render Script on farm render too. But on farm the Pre-Render Script does not find the same module which one in the scene is correctly working. Is it the farm or houdini problem ? Any idea ? Thanks. G

Hi, Is there a chance for example to get a picked position of a connection item ( where the pointer is picked its line ) ? I would place a node where it's picked.. I think the paste tool does similar when you pick a position at the Network Editor before paste. THX! G

Hi, Can Houdini python supports to get the nude under the actually shown node ring (or the object under mouse pointer )? G
