Update existing node menu items with Python 'OnCreaded' May 6, 2024, 2:40 a.m.
Goal: add an item to the Karma LOP -> Image Output -> Filters -> Tonemap menu item and save the updated parameter interface with Python.
Issue: menu item is updated with a new item but parameter interface (
It doesn't show in UI but via

I've tried to create the exact same menu via StringParmTemplate [www.sidefx.com] because
What am I doing wrong?
Thank you.
Issue: menu item is updated with a new item but parameter interface (
parmTemplateGroup()) doesn't save it. It doesn't show in UI but via
print()it shows.Context:
- Karma LOP.
- Created script name:
karmarenderproperties_OnCreated.py - Created script location:
C:\Program Files\Side Effects Software\Houdini 20.0.653\houdini\scripts\lop
Code I use to add an additional menu item to already existing ones:
# get Karma LOP node node = kwargs['node'] # get all parameters from Karma LOP parm_group = node.parmTemplateGroup() # get 'tonemap' parameter tone_map_param = node.parm('tonemap') # get parameters from 'tonemap' tone_map_template = tone_map_param.parmTemplate() # Update the menu item template with the new item template tone_map_template.setMenuItems(tone_map_template.menuItems() + ('AnimGraphLab',)) tone_map_template.setMenuLabels(tone_map_template.menuLabels() + ('AnimGraphLab',)) print(parm_group.find('tonemap').menuLabels()) # ('No Tonemapping', 'Reinhard', 'Ward', 'Unreal', 'Aces', 'Hable', 'Hable2') # Replace the existing menu template with the updated one parm_group.replace('tonemap', tone_map_template) print(parm_group.find('tonemap').menuLabels()) # ('No Tonemapping', 'Reinhard', 'Ward', 'Unreal', 'Aces', 'Hable', 'Hable2', 'AnimGraphLab') # save Karma LOP parameters layout with new updates node.setParmTemplateGroup(parm_group)
I belive something is with
node.setParmTemplateGroup(parm_group)since parm_group.replace()adds a new item.I've tried to create the exact same menu via StringParmTemplate [www.sidefx.com] because
node.parm('tonemap')type is a String [www.sidefx.com], and it was updated (image below):# get Karma LOP node node = kwargs['node'] # get all parameters from Karma LOP parm_group = node.parmTemplateGroup() menu_template = hou.StringParmTemplate(name='tone_map', label='Tonemap', num_components=1, menu_items=('off', 'ward', 'unreal', 'aces', 'eminem'), menu_labels=('no tonemap', 'ward', 'unreal', 'aces', 'Eminem'), ) # insert menu items as a very first paramter param_to_insert_before = parm_group.find("quicksetup") parm_group.insertBefore(param_to_insert_before, menu_template) desired_label = "AnimGraphLab" existing_labels = menu_template.menuLabels() if desired_label not in existing_labels: new_menu_items = menu_template.menuItems() + (desired_label,) new_menu_labels = existing_labels + (desired_label,) # Update the menu template menu_template.setMenuItems(new_menu_items) menu_template.setMenuLabels(new_menu_labels) # Update the parameter template group with the modified menu parm_group.replace('tone_map', menu_template) # save Karma LOP parameters layout with new updates node.setParmTemplateGroup(parm_group)
What am I doing wrong?
Thank you.
Comparing embedded images in an HDA help card? May 1, 2024, 3:54 a.m.

Man having to put the images into a .zip manually is UX horror. They really should've made it work with embedded images and external URLs.
Possibly there's another, proper way that somehow does all those mentioned steps automatically
But yeah, using [Image:opdef.?<IMAGE>]would be much more intuitive and expected P.S. - I've submitted enhancement request.

After some digging...
Houdini markup page example images are stored at this path:
Using the absolute path to images also doesn't work:
Solution:
1. SideFX team, please, update Compare Images Markup documentation [www.sidefx.com] 💛
2. Copy-paste your images inside
