The Tree Editor is a feature of nXt which allows you to create definitions for Fractal Trees, save them as .ArPlant files and then use them as plants in nXt.
It uses the nXt Tree Editor to create custom trees, stores a 2D representation of the tree in SketchUp and renders it as a full, fractal, 3D Tree.
Mapping to IRender nXt Plant
After creating an ArPlant in the Tree Editor and saving it, you can map it to a Revit Family.
Tree Editor usage
Set the type from the Type menu at the top.
There are four tree types - Standard, Conifer, Broad Crown, Palm and Complex
(Do not use Groundcover with RpTreeMaker).
Each has different setting on the tabs of the tree editor.
Play with the various settings to see what they do.
Foliage and Flowers
You can click on the leaf image to select a different image.
You can also add an image to be used as flowers or fruit
You can select new leaves, trunk, etc. by clicking on the image.
You can also add your own leaves and bark to the Plant Image folder and use them for your custom trees.
Click 'Start' on the RayTrace drop down menu to see a sample of the tree with foliage.
Users of rendering products besides IRender nXt have discovered that they need to explode the tree component, explode the image entity into a face, and remake to tree component in order to get the tree to render properly.
For IRender users, the RpTreeMaker tree will automatically re-render as a full, fractal, 3D tree.
IRender users should make their tree images at the lowest resolution to save time and keep the SketchUp model fast and small. After the tree is re-rendered the original image resolution will not effect the final image.
There is a Settings menu which lets you set:
- Background mode while rendering (this had nothing to do with the final image, but the HDRi setting gives you some sense of how the HDRi illumination works - If turn it on you will see that the tree is illuminated in a forest with the sun shining from behind on the left)
- default Illumination of the image. -(Smaller numbers make the image brighter)
- HDRi sky rotation for illumination. (55 degrees leaves the tree half in light and half in shadow)
Note: If your alpha transparent images do not display well in SketchUp, you can adjust the quality (vs speed) of Alpha Image display.
- Set it to 'nicer' for the best tree display.
- The Tree Editor allows you to choose from four types of trees (more coming soon.)
- .ArPlant files can be saved and loaded in the editor.
- .ArPlant files can be loaded into SketchUp for rendering.
Some Limitations on Trees (still numerous)
- Shrubs may be difficult to do in the current interface.
- We don’t have templates for things like Herbaceous Plants yet.
- You can’t change anything about the trees at the moment.
