I figured out how to do it (it's under "Add Misc" objects in the menu). It's just a shame that there seems to be no means for the program to import models in other formats (like 3ds, obj, fbx or whatnot) as then this crashing thing wouldn't be an issue and one could just re-import the models exported through other formats, but as it stands it seems you're stuck with either it working with your particular model or not. If the issue with the crashing on large models during export were fixed or resolved somehow, this could be a really nice quick representation tool to have at one's disposal. The quality is more or less what's to be expected from a GPU renderer, although there's really nice features such as with the changing seasons in real time, Sky, wind and sun positions also in real time and a nice library of trees and entourage objects (with animations) as well as cutting planes like we would have in ArchiCAD or Sketchup. etc)įrom what I've seen with the single family houses I've been able to export out to LumenRT, it seems like a really great program with a very intuitive interface and really smooth interaction (for my system) and a nice fps feedback. I've been able to export the same models out of ArchiCAD to other render engines (Maxwell,) and also as standard 3D formats (3ds, obj. I have a relatively powerful system (24 GB Ram, 8-core AMD CPU, a NVIDIA GTX GeForce 970 w/ 3GB Video memory and an older NVIDIA GTX GeForce 660 also w/3GB Video memory), so I don't really see what the issue could be. I tried an 20 storey multi-unit residential and also a 5 storey multi-unit residential and both times the program just crashes mid-export and this happens in both ArchiCAD17 and 18.
I would be curious to know how to got a clean export out of ArchiCAD with that model since it seems relatively large and so far with my tests with the program I've been unable to export anything larger than a two-level single family house out of ArchiCAD as I always get a crash and the Graphisoft Bug reporter screen when I've tried. The following links explain much better than me. Morph the landscape, add vegetation, people, cars, etc. Change materials in the model to LumenRT 2015 materials where desired Move the building to somewhere nicer in the landscape, and/or replace the tarmac with a different material.
Open LumenRT 2015: Your model will be arbitrarily placed on a patch of tarmac in your chosen landscape.
View the elements you wish to export in the 3D window, and export using the plugin menu command. Construct the building in ArchiCAD, including adjacent terrain if the building includes sunken pools, basements, etc. The Geo version is for those working more in the fields of urban planning and engineering: The key element being the integration with appropriate software.
So far, the software is working very well: The core LumenRT 2015 version allows one to morph the terrain inside the program, and add vegetation, vehicles, people (all animated, with wind effects, etc.).Įqually, there are 'proxy' elements that can be added inside ArchiCAD: There is no obligation to 'populate' your model inside ArchiCAD - my understanding is that it is a useful means of adding key elements to the ArchiCAD documentation that are important even in more 'technical' presentations (trees inside malls, vehicles in a car showroom, etc.). I'm still getting to grips with LumenRT 2015, so I'm a long way from being even a pimple on a guru's backside.
