Export 3D model to a game or FPS-style navigator
-
Hello, I am an architect who uses SketchUp, Revit and AutoCAD to create 3D models. I am very frustrated by how difficult it is to inspect these models, and get a feeling of how it will look. Sketchup walthrough is great, but very slow and laggy with big models. The other programs are hopeless, I don't want to export an animation, but simply to walk around the model/landscape like I do in Battlefield, Mount&Blade or any other game.
Why has no 3D modelling program managed to make a walkthrough engine as intuitive, fast and useful as the simplest FPS game? And more importantly, is there any software or game that lets me import my 3D model to walk around in? Maybe some open-source game that allows imported models in CAD or 3D object format? I simply want to look around using WASD control and mouse to look around, I don't care if it means a gun and crosshair must be included.

Hi ICD,
There is Unity3D with excellent walkabout functions. If you can spare some money, there is also LightUp (currently it seems that there has been to much interest as the developer also announced in another topic).
This will render your model photorealistically, bakes the rendered textures into the model (including shadows so they won't tax your system afterwards) and then allows you to either export to Unity3D or it even has a native Viewer which you can also use to walk around your model.
SketchUp itself is more a modelling software and due to its inferencing engine and all the other necessary stuff, it can easily become sluggish with complex models for such a job as walking through (although not impossible IMO).
