The Grove plays well with other 3D software. Transferring a 3d tree model to your favorite software is easy. The branches are simple polygonal objects that will export well with the OBJ file format. This includes UV maps. Best of all, the Grove’s unique twig system works great in every software we tested. Put to the test so far were Cinema 4D, Modo, LightWave and 3ds Max.
You can always export your tree with the twigs converted to full geometry, but where’s the fun in that? You will have all the troubles of stock 3D models. Big file sizes, huge memory consumption and low flexibility.
Luckily, most if not every 3D software has some way of duplicating objects from face centers, with using the face normal as a heading. Below are short tutorials on how to get trees into several 3D packages in keeping with the benefits of twigs.
What stands out is that every software expects a different initial rotation of the twig. To prepare a twig for export, some straightforward rotations ensure proper alignment. Click on your 3D software to learn more. Listed in alphabetic order:
There are two ways to get your tree to 3ds Max. The first of which is simply exporting to FBX. Once open in 3ds Max, this will have created every twig as a linked object instance.
The second option works like The Grove’s twig duplication system in Blender, and it works great in 3ds Max. Like other software, it requires a different orientation for twig objects. Before exporting a twig from Blender, it must be rotated. Select the twig and press N to show the object’s properties. For the rotation, enter X: -90, Y: -90 and Z: 0 degrees. Press Control+A and select Rotation to bake the new rotation into the mesh. Now export the twig as an OBJ file.
Import the separate objects for branches, twig duplicators and the twigs into 3ds Max.
To duplicate the twig along the twig duplicator object, first select it. Head to the Create tab, click the Geometry icon, select Compound Objects from the drop down, and finally click Scatter. Head to the Modify tab to configure the duplicator. First pick the duplicator object and use the twig duplication object for this. Check All Face Centers to get all the twigs needed to fill the tree. 3ds Max has plenty viewport “sauce” and it won’t handle the enormous amount of geometry well. To get a workable view, scroll down to Display Options. Either lower the percentage of twigs shown, or use a proxy object.
That’s it, your tree is now inside 3ds Max.

Importing a Grove tree couldn’t be easier in Cinema 4D. Select the branches, the twig duplicator objects and the twig models you used to grow your tree. Export to OBJ and check the box for Selection Only (in the lower left of the export screen). Import the OBJ file with all settings at default. Your tree’s branches and the twig are now in Cinema4D with UV’s. All that’s left is to redistribute the twigs.
Cinema 4D has a set of tools called MoGraph, that will make this easy. Add a MoGraph Cloner to your scene and drag the twig object into the Cloner. Click on the Cloner object and open the Object tab. Set Mode to Object and pick the twig duplication object. To properly align the twigs, check Align Clone, with an Up Vector of Y+ and set Distribution to Polygon Center.
Create an extra Cloner for your lateral twigs if you use one. Great, your tree is in Cinema4D with all the benefits of the twig system!

The Grove’s trees work beautifully in LightWave and you can take advantage of the convenient twig duplication system.
Export the separate OBJ objects for branches, twig duplicators and the twigs themselves, then import them into Layout.
The twig duplicator is a mesh object where each tiny polygon represents the placement and rotation of a twig model. Open up the Object Properties for this object. Head for the Instancer tab and add a new Instance Generator. Then double-click it to configure the generator. Click Add Object and select the twig object you imported.
The idea is to place a twig for each and every face. To do this, select Polygons as the duplication type and check Max Polygons. To better see what’s happening, change the draw type of the instances to Shaded Solid. Do this by clicking the small cube symbol beneath the eye symbol in the list on the left. You’ll see that the placement is correct, but the rotation isn’t, so head to the Rotation tab in the lower right. Change the Alignment to Normals and things will have improved, but it’s not quite right just yet. This is because Blender and LightWave’s duplicators require a different orientation of the twig. To fix this, select the twig and press Y to rotate it. In the lower right of the LightWave window, enter a Heading of -90, a Pitch of 180 and a Banking of -90 degrees.

The Grove user PaQ WaK has put up a tutorial on getting the twig system into Modo. Using Replicators, all the benefits of twigs are kept. Like other software, Modo also requires a specific rotation of the twig model, different from Blender’s.
