The Spatial Sync add-on for SimLab Composer allows you to perfectly align your virtual 3D content with your real-world physical space. This is essential for Mixed Reality (MR) experiences, where a full virtual interior (like a new kitchen layout) needs to sit ...

Node Entered Node The Node Enter Node event is triggered when Scene Node A enters Scene Node B. Both nodes can be any nodes in the assembly tree — for example, Node A could be a screwdriver and Node B could be a screw. Node Exited Node  The Node Exc...

Set Interaction Mode The Set Interaction Mode node dynamically changes how participants engage with the VR environment. When activated, the node evaluates the targeted User input—which can be configured for either "Host Only" or "All Users" and immediate...

These event nodes watch an object and fire automatically the moment one of its attributes changes — so you can react when an attribute is added, edited, or removed without having to keep checking for it yourself. They pair naturally with the Set Node Attribute...

Node Added to Query   The Node Added to Query event node constantly monitors the scene and triggers its Execute output whenever a 3D object's attributes are modified to match the specific conditions defined by a connected Scene Node Query. By plugging a q...

A material decides how a surface looks in your scene — its color, how see-through it is, and the image (called a texture) painted across it. The nodes on this page let your scene read and change those looks while it is running: fade an object out, recolor a wa...

Is Node Visible This node checks the current visibility state of a specified 3D object within the VR Viewer. It evaluates whether the targeted object is currently rendered (shown) or hidden in the scene, and outputs this status as a boolean value (True o...

Set Texture From File This node replaces the current texture of a specified material with a 2D image file stored in your Resource Management system. By inputting the exact file name, you can dynamically update the visual appearance of any object using that...

 Get Node Children The Get Node Children enables the user to retrieve child SceneNodes from a specified parent node within the hierarchy in the scene browser. This function allows users to access the children of a parent node in the VR environment, facilita...

Record Sound The Record Sound node initiates an audio recording session within the VR experience. This node utilizes a User dropdown parameter to determine whether the system captures microphone audio exclusively from the host or from all participating u...

The Add-ons Manager serves as the central hub for extending the capabilities of SimLab Composer. It allows you to discover, install, and manage extra tools—like the CSV Attribute Manager or Gamepad Integration—to customize your workflow. Accessing the Manag...

Dynamic Menu Item Triggered   The Dynamic Menu Item Triggered event node acts as a universal listener, activating the moment a user interacts with any dynamic menu button within the VR scene. Upon execution, it outputs the specific SceneNode the menu is a...

Node Ready To Snap   The Node Ready to Snap event node activates the exact moment a designated SceneNode enters the valid snapping range of an eligible target. This node is highly useful for triggering immediate visual or audio feedback—such as highlighti...

Can Snap Node The Can Snap Node checks whether a specific SceneNode is currently within the eligible snapping range of another object. This node evaluates the spatial relationship between objects and outputs a "Possible" boolean to confirm if a snap can oc...

Custom Event  This event is activated manually by the user. It's useful when you want multiple different paths or actions to lead to the same response. To set it up, use the Trigger Custom Event response and assign it a unique ID (e.g., path1). You can pl...

Set Video File The Set Video File node allows you to dynamically attach or change the media source of a specific Video Node within your scene. By assigning the target Video Node and inputting the exact FileName of your desired video (such as an .mp4), th...

Set Dynamic Menu Visibility The Set Dynamic Menu Visibility node controls whether dynamic menus (specifically used with the Objects Menu and Group Menus add-ons) are shown or hidden during a VR experience, using a boolean toggle where True displays the m...

Open External Connection SimLab Composer 14 introduces WebSocket support, enabling seamless integration with external systems allowing it to work with external hardware, co-simulation engines, and websites, unlocking numerous possibilities. The WebSocket ...

AI Agent Start Talk The AI Agent Start Talk node activates the exact moment an assigned AI Agent begins delivering its response. AI Agent End Talk The AI Agent End Talk node activates as soon as the assigned AI Agent finishes delivering its re...

Ignore grabbing The Ignore Grabbing node explicitly prevents a specific 3D object from being picked up or interacted with by the user's hands during the VR experience. When activated, the node disables the grabbable state of the targeted SceneNode if set...
