What is Live Link?

Live Link allows you to work simultaneously on Rhinoceros and Unreal Studio without worrying about moving assets from one software to the other and without going through Unreal Datasmith. This will save you a lot of time. 


While a Live Link connection is established between Rhino and Unreal your Rhino 3D model is twinned in the Unreal scene. This means that any change made on the 3D model in Rhino immediately affects its Unreal twin.


You can use this technology to boost your design workflow as you skip many export phases and view your models fully rendered with real-time raytraced lights and materials while modeling. Also, experiencing your CAD models within a realistic context (i.e. a city, a bay, a forest, an exhibition stand, etc.) helps you understand how your work will feel once built.


Session survival

Linked CAD objects are temporary and will persist in the Unreal scene as long as i. the Live Link itself is active and ii. both Unreal and the source CAD are running. Interrupting one of those will make your linked CAD objects disappear from the scene. However, Unreal will store what you do with a linked object in a cache and, when the link is re-established with the same file, your assigned materials and Root Actor properties (like scale and position) will be still there.


First connection

To connect Rhino to Unreal, follow these steps:

  1. Launch both Rhino and Unreal and related projects
  2. From Rhino top toolbar, click 'Mindesk' and then 'Connect Unreal'
  3. If this is your first Mindesk use a prompt might ask you to insert your Mindesk Account credentials and assign a license to your workstation
  4. Once launched a connection from Rhino, go on Unreal and click 'Connect Mindesk'
  5. Your Unreal scene will populate with the linked Rhino model, now you can use the Mindesk root actor to adjust the linked model position, scale and rotation with respect to the Unreal scene

Once the connection is fully established (might take a few seconds), you should get the following result:

Some faces are not displayed correctly, What do I do?


DON'T PANIC!


Sometimes Rhino faces are flipped (you can visualize this with Rhino display option, first picture), Unreal will render flipped surface as transparent (second picture), however, as soon as you assign a double-faced material to the linked model, it will be rendered properly (third picture).


Recommended: always use double-sided materials in Unreal
