I create a usd file named “zeroSample.usd”, I am trying to add it to stage as reference by following code:
The reference zeroSample added successfully in the stage, but assets in the original USD files are invisible.
[Warning] [omni.usd] Warning: in _ReportErrors at line 2830 of /buildAgent/work/ca6c508eae419cf8/USD/pxr/usd/usd/stage.cpp – Could not open asset @file:/home/isaac/Documents/Prj/Zeros/zeroSimple.usd’@ for reference on prim @anon:0x17c2b7a0:World8.usd@,@anon:0x7fb19c0655d0:World8-session.usda@</World/zeroSample>.

@liuyuanyuan.sh not sure if you’ve already resolved this problem since it’s been a few weeks. i am wondering if this code snippet is somewhat relevant - Create a Reference — Omniverse Developer Guide latest documentation
@Simplychenable , Unfortunately I did not solve this problem.
I tried the method in the link you posted, got the same prompt “recomposing stage on stage”.
The context of my programming is extension APP.
As the following picture, I can print the USDA file, but can not see any thing in the viewport.
I skipped this issue by following code, but it is not added as “reference”.
async def open_stage(self):
(result,error)=await omni.usd.get_context().open_stage_async(self._path) #"file:/home/isaac/Documents/Prj/Zeros/zeroSimple.usd"
if not result:
print(f"Errors: on open stage")
- How to solve the problem of “recomposing stage on stage”?
Does the “zeroSample.usd” have a default prim?
and just fyi, the URL i meant to link was “Create a Reference” and not “Add a Reference”. i’ve made the necessary change to my last post, sorry for the confusion.
it can be as short as…
from pxr import Sdf
and to iterate, this is assuming zeroSample.usd has a defaultPrim; otherwise, the content of the usd won’t come through.
I tried your last post and create the zeroSample reference successfully.
So "add" command contain another stage in the reference?
Thank you so much! ^_^
