With the new Lumion 7.3 the Revit to Lumion workflow is better than ever! For one, it makes it easier to navigate the model while designing, and if one is planning to use the materials in Revit to define what the model is going to look like (allowing uniformity between Revit and Lumion renders), then it is a very good feedback tool. If one would like to apply materials using Lumion, however, then one would have to export and apply materials as usual.

Choose the settings required.
Press “Play” and insert it into Lumion.
As can be seen there is now a much closer resemblance between Lumion and Revit materials. This makes it possible to manipulate the materials from within Revit to synch to Lumion.
In fact, one is not allowed to edit materials that are being live synched into Lumion:
Even when, as shown below, live synch is switched off.
Changing the paving layer in Revit now updates the Lumion model.
Also, if objects are added or modified in Revit, they are automatically updated in Lumion. Here a column, decals (using cut-out masks) and trees (RPC) content is added.
While the column and decals are ported, the cut-outs are not applied. And as can be seen below, RPC content is not transferred at all. No trees, motor vehicles or people were synched to Lumion.
The upshot of it is that while modelling should be done in Revit (Including material definition), Placement of motor vehicles, people and plants should be done in Lumion.
The Lumion model may be exported as usual as a .DAE file, in which case materials may be applied as usual
