Importing your own 3D models

COLLADA is an XML namespace and database schema that allows you to move 3D files between 3ds Max, Maya, Revit, and Lumion. Each application is different, but in most cases, we just need to export or save our scene as a COLLADA file or an FBX file.

Let's start by launching Lumion with the following steps:

This recipe is a really straightforward task as you can see, but is one of the most important tasks once you start working with Lumion. It is at this stage that you can be sure that everything is OK with your 3D model and make sure that you don't have any missing faces or other geometry problems. This step also assists you in checking if you have worked with the correct scale, so if your model is either extremely large or very small, you need to go back to your 3D modeling package and correct the scale. With all these things in mind, we now have a good base to start working with Lumion.

Another tip; we sometimes overlook the reality that even though Lumion is a very powerful application and can handle millions of polygons, it still has limits. So, if initially you just want to organize and populate your scene without paying too much consideration to the 3D model itself, it is good to create a proxy or a simple representation of your 3D model and import that proxy, and then later with a special feature in Lumion, reimport your high-poly model.
