1 When we are doing landscape for one model in Lumion, can we separate the work into several computers and combine all individual parts into the same model after each computer's work is done.
Hi Kevin, you can move models between different PCs by manually copy-pasting the model files (My Documents/Lumion 2/Library
). Once you have put all the relevant model files into this folder on a single PC, restart Lumion, place the various models in your scene and use the Align
command (Context Menu -> Transformation -> Align
) to make all model parts use the same position and rotation. You can also type in positions via the Edit Properties
2 Regarding the building model, we use 3D Max software to make it and input the building models into Lumion. When there are too many buildings, the computer can't work smoothly. It may get stuck. Have you got any suggestion to solve this problem without degrading the resolution?
If you turn on the "i" button in Settings, you will be able to see how many vertices your scene consists of in the top right corner of Build
mode. "k" means 1000, so 300k = 300000 vertices. Sun shadows double the vertex count, so 300k means that your model + the terrain + any other stuff that is rendered use 150000 vertices.
If your goal is smooth performance and fast render times, try to keep this number as low as possible.
Performance is obviously also a result of the graphics card you're using, whether you're using Windows 64-bit and so on. This is described in more detail here:http://lumion3d.com/forum/f-a-q/how-to-reduce-render-times-in-lumion/
In addition, some more of the settings that affect performance in Lumion are:
- Lumion window resolution (depends on your monitor and if the window was maximized or not)
- Editor quality (1-4 stars)
- Render quality (1-3 stars)
- Editor Resolution
- IES lights (Edit Properties -> Shadow cache on/off)
- (F7): See the Terrain without automatic culling at the maximum level of detail.
- (F8): Press F8 to turn on real-time shadows for IES lights.
- (F9): If you press F9, all trees and plants in the viewport will be rendered at their best level of detail, so that it's easier to see where you need to add more trees and plants in a scene.
3 Regarding the vegetation, the variety of plants in Lumion is not enough for us. There is no Liane in Lumion. We use speed tree software to make tree model, however, speed tree software still doesn't have the Liane. Could you offer us some suggestion in this regard?
Lumion requires SpeedTree 5.1. If you have that version you can create a tree, and save all the compiled tree files into a new folder with a unique name ("LumionInstallationFolder/Trees/CategoryFolder/YourTreeName
") - just make sure your new folder name and .srt name do not already exist in Lumion's Trees
Then restart Lumion and navigate to the tree category where you put your new tree model. The thumbnail image will be brown. Place that tree in your scene, select it, and press the CTRL-key while left-clicking on the brown thumbnail image to update it.
4 When I input one model into Lumion, is it possible to split this model into explosive fig or make any animation for this model in Lumion? Such as making building construction procedure animation within Lumion. Does Lumion have this kind of function? Or how could we do it?
Search for the 'Sky Drop' effect. The 'Camera clip planes' effect might also be useful
