Hi @RongXingDaMoWang, thank you for your feedback. Can you paste the complete traceback of Errors so we can look into this issue? |

I think I'm experiencing the same error when excuting h1_house.py? @HanqingWangAI The complete error is here: `Starting kit application with the following args: ['/home/percy/.local/share/ov/pkg/isaac-sim-2023.1.1/exts/omni.isaac.kit/omni/isaac/kit/simulation_app.py', '/home/percy/.local/share/ov/pkg/isaac-sim-2023.1.1/apps/omni.isaac.sim.python.kit', '--/app/tokens/exe-path=/home/percy/.local/share/ov/pkg/isaac-sim-2023.1.1/kit', '--/persistent/app/viewport/displayOptions=3094', '--/rtx/materialDb/syncLoads=True', '--/rtx/hydra/materialSyncLoads=True', '--/omni.kit.plugin/syncUsdLoads=True', '--/app/renderer/resolution/width=1280', '--/app/renderer/resolution/height=720', '--/app/window/width=1440', '--/app/window/height=900', '--/renderer/multiGpu/enabled=True', '--/app/fastShutdown=True', '--ext-folder', '/home/percy/.local/share/ov/pkg/isaac-sim-2023.1.1/exts', '--ext-folder', '/home/percy/.local/share/ov/pkg/isaac-sim-2023.1.1/apps', '--/physics/cudaDevice=0', '--portable'] |---------------------------------------------------------------------------------------------| Active user not found.

@HanqingWangAI ，Hello, thank you for your great work. I have encountered the same problem as @percypeng5221 and @RongXingDaMoWang . May I ask what is going on? |

Hi @RookieXwc @percypeng5221 @RongXingDaMoWang, we basically located the issue. It is caused by the in-compatible way of generating approximated collider for rigid bodies. We are still solving the errors. A temporal workaround is to disable all rigidbody in the scene and adopt from pxr import Usd, UsdPhysics, UsdGeom
def set_collider_(mesh, approx=UsdPhysics.Tokens.convexDecomposition, init_state=True):
"""set collider for a mesh
Args:
- mesh: Usd.Prim -> Mesh
- approx: Convex approximation method, e.g. ConvenDecomposition, ConvexHull
- init_state: init state of collider(whether activate)
"""
if mesh.GetTypeName() == "Mesh" and UsdPhysics.CollisionAPI.CanApply(mesh):
collider = UsdPhysics.CollisionAPI.Apply(mesh)
meshcollider = UsdPhysics.MeshCollisionAPI.Apply(mesh)
meshcollider.GetApproximationAttr().Set(approx)
collider.GetCollisionEnabledAttr().Set(init_state)
def set_collider(item, approx=UsdPhysics.Tokens.convexDecomposition, init_state=True):
"""set collider for all meshes of an Usd.Prim
Args:
- item: Usd.Prim, e.g. Xform
"""
if len(item.GetChildren()) == 0:
set_collider_(item, approx, init_state=init_state)
for i in item.GetChildren():
set_collider(i, approx, init_state=init_state)
def remove_collider_(mesh):
if mesh.GetTypeName() == "Mesh":
mesh.RemoveAPI(UsdPhysics.CollisionAPI)
mesh.RemoveAPI(UsdPhysics.MeshCollisionAPI)
def remove_collider(item):
if len(item.GetChildren()) == 0:
remove_collider_(item)
for i in item.GetChildren():
remove_collider(i)
def remove_rigid_(prim):
prim.RemoveAPI(UsdPhysics.RigidBodyAPI)
if prim.IsA(UsdPhysics.PrismaticJoint) or prim.IsA(UsdPhysics.RevoluteJoint):
attr = prim.GetAttribute("physics:jointEnabled")
attr.Set(False)
def remove_rigid(item):
remove_rigid_(item)
for i in item.GetChildren():
remove_rigid(i)
def bind_static(prim):
remove_collider(prim)
remove_rigid(prim)
set_collider(prim, "meshSimplification") |
Hello, may I ask in which file this code was modified? |
您好，感谢你们的分享，我在在运行城市和房屋的demo的时候，提示如下问题，希望能够得到解决，感谢
