In my own compiled version of 2.92 Alpha, the Add Menu (SHIFT + A) is empty for the Geometry Node Editor, but if I download a precompiled daily build the add menu has all the Nodes: Attribute, Color, Geometry…
I get errors in the console like:
…\2.92\scripts\startup\bl_ui\space_userpref.py:2158
rna_uiItemR: property not found: PreferencesExperimental.use_new_point_cloud_type
…\2.92\scripts\startup\bl_ui\space_userpref.py:2158
rna_uiItemR: property not found: PreferencesExperimental.use_new_geometry_nodes
Ideas for how to get the Add Menu working in my own build?
