Hi, I'm working with Apprentice 18 and loving it. However, I don't understand why I'm getting permissions error when I try to add any of the shelf Terrain FX such as Terrain: Mountain. It doesn't work in either:

1. the obj context:
   
2. inside a geo(hda) node, which is not locked
   

Both return the samer error window message: Cannot create a node inside a locked asset.

Also, I'm unable to add any of the Test Geometry in the obj context. For example, when I try to add the Pig I get the error message:

Failed to modify node or parameter because of a permission error. Possible causes include locked assets, takes, product permissions or user-specified permissions.

So you can't make any nodes? What platform is this? Sounds like a corrupt installation or a bad hda is taking over for built-in ones.

Edit:
You said “geo hda (unlocked)”. The geo node is not an hda. Saving an HDA called “geo” will completely break houdini. I would save that as something else, and delete the one called ‘geo’, if that is the case.
