Save Viewport Overrides (scene graph tree) Jan. 10, 2025, 9:34 a.m.
Hi, I'd like to export the Solaris scene graph viewport overrides outwith the current session.
I naively thought something basic such as this would work as I can return the current overrides list and clear them as described here https://www.sidefx.com/forum/topic/86934/?page=1#post-375436 [www.sidefx.com]
This is in 19.5 and I notice there might be different using usd layers https://www.sidefx.com/docs/houdini/hom/hou/LopNetwork.html#viewportOverrides [www.sidefx.com]
I may be missing a vital bit of info but I don't get any result with is either and I noted there is an explanation in the doc that
Is there any other way to save the Scene Graph panel overrides?

Hi, I've been trying to do various things related to this. I can get coordsys to do what I need but there is a note in the docs:
Coordinate Systems works, as does a camera path but I haven't managed to get 'paths to an xformable prim' to work. Perhaps it's a syntax issue?

The space to which the position should be transformed.
Karma supports paths to an xformable prim, or a camera. Also supported are Coordinate Systems.

Hi,
I've stumbled upon this thread and looked into the example. There's an issue with the geo path in the swirl_mesh_topology usd in that it is a full path. In the swirl_mesh.usda they are relative. Is this by design? I have to manually/post process this usda to have a relative path to work cross platform at the moment. Well, when I say 'work', it works OK but there will be problems if the metadata is required.
Cheers,
J
