enquel Posted February 11, 2015 Share Posted February 11, 2015 (edited) Hello, How to hide a primitive group from rendering? I have a character utlizing auto rig, I use the same rig for naked and clothed version of my character, and want to select parts of the body I don't want to render (obscured by clothes), because I expect and already see some parts of body see-through my clothes. Just look at attached renders and you'll know what I mean: Thanks in advance, Artur PS. Please check out my sites at the footer, I am looking for freelance work. --- Artur Mandas 2D/3D Artist & Developer www: http://arturmandas.wordpress.com horizon: http://horizonthemovie.wordpress.com mobile: +48 694087492 skype: artur.mandas1 Edited February 11, 2015 by enquel Quote Link to comment Share on other sites More sharing options...
enquel Posted February 11, 2015 Author Share Posted February 11, 2015 I've found this: vm_geometrygroup / object:geometrygroup = ('') which means setting a group string to empty at mantra property paramater, but this disables rendering of the whole object - I mean no matter what primitive group I set, like vm_geometrygroup / object:geometrygroup = ('group1') it doesn't see it, and just stops rendering the whole object. Anyone? Quote Link to comment Share on other sites More sharing options...
michael Posted February 11, 2015 Share Posted February 11, 2015 easiest way is to make groups of the hidden geometry and delete it Quote Link to comment Share on other sites More sharing options...
Martin47 Posted February 11, 2015 Share Posted February 11, 2015 try to select the faces of your geometry that you want to remove, press Ctrl-I to invert your selection, create a group and name it. go to mantra node and edit the parameter interface, in rendering tab, filter "vm_geometrygroup" add to existing parameters and apply it, then put the group name in the string.

enquel Posted February 12, 2015 Author Share Posted February 12, 2015 easiest way is to make groups of the hidden geometry and delete it Thank you, but I have to keep the number and order of vertices intact - I want my blend shapes to work properly. try to select the faces of your geometry that you want to remove, press Ctrl-I to invert your selection, create a group and name it. go to mantra node and edit the parameter interface, in rendering tab, filter "vm_geometrygroup" add to existing parameters and apply it, then put the group name in the string. Thank you, I did that, and as I wrote, it just stopped displaying the entire object (regardless the name of the group in the input string). Maybe I put that parameter in the wrong place, but I tried applying it to my geometry both at object and group node level. Quote Link to comment Share on other sites More sharing options...
sadhu Posted February 12, 2015 Share Posted February 12, 2015 (edited) "vm_geometrygroup" , working for primitive groups (H 13.0.478). Deleting option should also work if you are rendering in houdini. Delete the unwanted group after deformation before rendering.

Delete the unwanted group after deformation before rendering. I have H 13.0.547. I am sorry, but I do not understand what you were trying to convey. Could you be more clear?

michael Posted February 12, 2015 Share Posted February 12, 2015 it's from the Journal: https://www.sidefx.com/index.php?option=com_journal&Itemid=213&page=index&journal=default this lists all the updates to Houdini... so in Houdini 13.0.478 and above this has been fixed.
