Get a Reference to a prim¶
Getting references to prims lets you read and write to their attributes and lets you pass them to APIs.
Get a Reference by using the prim’s stage path¶
usd_context = omni.usd.get_context() stage = usd_context.get_stage() my_prim_path = "World/building/window/" my_prim = stage.GetPrimAtPath(my_prim_path)
Getting cached prims¶
For performance reasons some API’s use cached versions of prims and the stage.
prim_id is an ID to the cached prim with the path in the string var
stage_id is an ID for the cached stage.
from pxr import PhysicsSchemaTools, UsdUtils prim_id = PhysicsSchemaTools.sdfPathToInt(my_prim_path) stage_cache = UsdUtils.StageCache.Get() usd_context = omni.usd.get_context() stage = usd_context.get_stage() stage_id = stage_cache.GetId(stage).ToLongInt()
