Hello,

I am having trouble with a bizarre error I get when I import models from ArchiCAD 18 using the  ArchiCAD to Lumion Bridge (.dae). For some reason, when I get close to the object, it gets cut by the view plane, as if it wasn’t a solid object. I have tried updating the bridge add-on, tried exporting in other formats (.3ds, .skp), even tried exporting different projects, but so far, no success.

I have no clue to what could be causing this error. I have worked on other project before (back when I used ArchiCAD 17) on a licensed version of Lumion (version 4.something) and had no trouble. Have in mind that the projects I have been trying to export are BIM projects (fully modeled, including some complex terrain mesh). I would appreciate of someone could shine a light on this problem.

Thank you in advance.

Hi wthaylor, that's easily resolved.

It occurs if there's a significant distance between the camera and the Lumion terrain (and there's a good reason for it as it will prevent overlapping surfaces from flickering when the camera is far above the terrain).

If you place a model far above the terrain, you'll notice that the socalled "near camera clip plane" is moved away from the camera, so that the building in your scene is getting clipped.

To prevent this from occurring in Build mode, either move the building closer to the Lumion terrain - or click here to temporarily lock all models in your scene and then raise the Lumion terrain below the building, so that the distance between the camera and the terrain is as small as possible.

If you can't move the building closer to the Lumion terrain (or the Lumion terrain closer to the building), you will have to learn to live with it in Build mode. However, you can still prevent it from occurring in Photo/Movie mode when rendering images/videos by adding the following to your clips/photos: New effect -> Camera tab -> Near clip plane effect. Once you've done that, reduce the Near clip plane value and render the images/videos.
