I'm creating a custom property for each object in my scene but don't want the user to be able to edit it. Is it possible to block the property in ui ? Here is my code :

import bpy

allObjects = list(bpy.data.objects)

for element in allObjects:
    element["myProp"] = "My value"

You might create a custom property and pass only a get method:

import bpy

#default getter
def get_my_prop(self):
    return self['my_prop']

#omit the setter with a given getter to make it read-only
bpy.types.Object.my_prop = bpy.props.StringProperty(get=get_my_prop)

for obj in bpy.context.selected_objects:
    #assign the value directly
    obj['my_prop'] = "My Value"

It looks like this in the properties panel in blender 2.71: getter

  • $\begingroup$ That works very well but when I close and open the blend file, the custom property is editable again. I tried to use the options={'HIDDEN'} in my stringProperty but it doesn't hide my property... $\endgroup$ – Caligari Jul 16 '14 at 9:44

    $\begingroup$ You can either check the Register option in the text editor to run the script when the blend file is loaded or create an addon. #1 #2 $\endgroup$ – pink vertex Jul 16 '14 at 22:18

    $\begingroup$ In order to run the script upon scene loading, you could add your function in a permanent handler, with an @persistent decorator, as seen here: blender.org/documentation/blender_python_api_2_60_6/… This way, when you load a scene, the script runs automatically. $\endgroup$ – Pisurquatre Jul 17 '14 at 12:59
