-    a set of meshes with a given ray pattern.

 The Ray Caster sensor (and the ray caster camera) are similar to RTX based rendering in that they both involve casting rays.  The difference here is that the rays cast by the Ray Caster sensor return strictly collision information along the cast, and the direction of each individual ray can be specified.  They do not bounce, nor are they affected by things like materials or opacity. For each ray specified by the sensor, a line is traced along the path of the ray and the location of first collision with the specified mesh is returned. This is the method used by some of our quadruped examples to measure the local height field.
 
-To keep the sensor performant when there are many cloned environments, the line tracing is done directly in `Warp <https://nvidia.github.io/warp/>`_. This is the reason why specific meshes need to be identified to cast against: that mesh data is loaded onto the device by warp when the sensor is initialized. As a consequence, the current iteration of this sensor only works for literally static meshes (meshes that *are not changed from the defaults specified in their USD file*).  This constraint will be removed in future releases.

This is the reason why specific meshes need to be identified to cast against: that mesh data is loaded onto the device by warp when the sensor is initialized.
+
+The sensor supports both **static meshes** (fixed geometry) and **dynamic meshes** (moving objects). Static meshes are loaded once at initialization, while dynamic meshes have their transforms updated before each raycast operation. This enables raycasting against moving obstacles, dynamic platforms, or other robots in multi-agent scenarios.
 
 Using a ray caster sensor requires a **pattern** and a parent xform to be attached to.  The pattern defines how the rays are cast, while the prim properties defines the orientation and position of the sensor (additional offsets can be specified for more exact placement).  Isaac Lab supports a number of ray casting pattern configurations, including a generic LIDAR and grid pattern.

+Dynamic Meshes
+--------------
+
+The Ray Caster sensor supports raycasting against dynamic (moving) meshes in addition to static meshes. This is useful for:
+
+* Detecting moving obstacles
+* Multi-agent collision avoidance
+* Dynamic platform navigation
+* Reactive behavior in changing environments
+
+To use dynamic meshes, specify which mesh paths are dynamic using the ``dynamic_mesh_prim_paths`` parameter:
+
+.. code-block:: python
+
+    from isaaclab.sensors.ray_caster import RayCasterCfg, patterns
+
+    ray_caster_cfg = RayCasterCfg(
+        prim_path="/World/envs/env_.*/Robot/lidar",
+        mesh_prim_paths=[
+            "/World/envs/env_.*/ground_plane",  # Static mesh
+            "/World/envs/env_.*/obstacle",       # Dynamic mesh
+        ],
+        dynamic_mesh_prim_paths=[
+            "/World/envs/env_.*/obstacle",  # Mark obstacle as dynamic
+        ],
+        pattern_cfg=patterns.LidarPatternCfg(
+            channels=16,
+            vertical_fov_range=(-15.0, 15.0),
+            horizontal_fov_range=(0.0, 360.0),
+            horizontal_res=1.0,
+        ),
+        debug_vis=False,
+    )
+
+.. note::
+**Environment Origins Required**: The raycaster requires environment origins to correctly transform mesh coordinates from world space to environment-local space. You must call ``raycaster.set_env_origins(env_origins)`` after creating the sensor, typically in your environment's ``__init__`` method. This is required for both static and dynamic meshes.
+
+
+Dynamic Mesh Performance
+^^^^^^^^^^^^^^^^^^^^^^^^
+
+Dynamic meshes have a small computational overhead for updating their transforms. The sensor uses PhysX RigidBodyView for fast batched transform queries when possible:
+
+* **Static meshes only**: ~0.2-0.5 ms raycast time
+* **With dynamic meshes (PhysX views)**: +0.5-2 ms overhead (5-10x faster than USD queries)
+* **With dynamic meshes (USD fallback)**: +5-15 ms overhead (used when meshes lack RigidBodyAPI)
+
+To optimize performance with many dynamic meshes:
+
+1. **Ensure dynamic meshes have** ``UsdPhysics.RigidBodyAPI`` **applied** (enables fast PhysX views)
+2. **Use the** ``dynamic_mesh_update_decimation`` **parameter to update less frequently:**
+
+.. code-block:: python
+
+    ray_caster_cfg = RayCasterCfg(
+        # ... other parameters
+        dynamic_mesh_update_decimation=2,  # Update every 2 frames (50% faster)
+    )
+
+3. **Simplify mesh geometry** for raycasting (fewer vertices = faster updates)
+
+Profiling Dynamic Mesh Performance
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+To measure the performance impact of dynamic meshes, enable built-in profiling:
+
+.. code-block:: python
+
+    # Enable profiling on the sensor
+    raycaster = scene["lidar"]
+    raycaster.enable_profiling = True
+
+    # Run simulation...
+    for _ in range(500):
+        env.step(action)
+
+    # Print statistics
+    raycaster.print_profile_stats()
+
+This will output detailed timing statistics:
