QUESTION
How do you replace imported "proxy" objects with trees or lights?

ANSWER
The Place item on nodes function (Node Replacement) allows you to replace multiple imported "proxy" objects with trees/plants or lights of your choice.

It is available via the Context Menu for imported models:
Context Menu -> Extra -> Place item on nodes

The function only works with Revit, SketchUp and 3DS Max. For those using Rhino, there is an interim solution in this forum post. Please note that license registration is required to view it.


PROCEDURE:

Create some "proxy" objects in SketchUp, 3DS Max or Revit (e.g. some boxes) and import them in Lumion as a separate file:
  • 3DS Max: Each "proxy" object has to be a separate object with its own position/rotation/scale, for example some duplicated boxes (or vertical columns in Revit). DAE and FBX files are supported. .MAX files also work provided that you've got 3DS Max installed.
  • Revit: The Revit To Lumion Bridge will export a collapsed model which is unsuitable for use with the Place item on node function. For that reason, please export the "proxy" objects as an FBX file instead.
  • SketchUp: SKP format is ideal for "proxy" objects, but if you export to DAE format, please make sure that 'Preserve Component Hierarchies' is turned on.
TIP: When replacing imported "proxy" objects with Spotlights, please note that the "proxy" objects have to be rotated by 90 degrees in your CAD package to look correct after replacement in Lumion.


STEPS (USING SKETCHUP EXAMPLE):
1) Create a box for use as a "proxy" object and right-click on it -> Make component or Make Group. Duplicate the box as many times as you want. Then save the scene as a SKP (SketchUp) file.


   



2) Import the file in Lumion and place the "proxy" objects in the desired location (See this Knowledge Base article if you need to align the "proxy" objects with an existing model).




3) Select a tree/plant or light in the Model Library that you want to place at the same location as the imported "proxy" objects.




4) Click on the circular icon of the imported "proxy" model from 3DS Max/Revit/SketchUp -> Context Menu -> Extra -> Place item on nodes.

If you have the SKP file open, then a Windows Open File window will now pop up. Select the SKP file you saved earlier, and click on the Open button.  Otherwise, the nodes will now be used to position the Tree or Light you selected.




5) Remove the original imported "proxy" model to see the finished result:
