Date Updated: 

ATree3D is simple to use 3D plants generator for architectural visualizations. With this script for 3ds max you can create trees, bushes, flowers and grass. You can use it for low or high polygon models with precise control of the level of details on each sub-element. Script works inside of the 3ds max viewport and show instant preview of your changes.

If you like this script please share your plants and trees(.at3d files) with the community.

Alpha image

You can use meshes with or without alpha image. All the leaves in the included examples are only meshes without maps for the alpha channel.

Is the leaf an alpha image?

Great Script

thank you for sharing this

A great script I'm just

A great script I'm just dipping in to.

Would it be possible for some Vray support? I'd love to be able to pick a vray proxy for the leaves. ;-)

few issues

Hi arieas,
Thanks for the feedback.
Every now and then I get similar to the first error that you describe usually on a 32-bit system with big tree. I believe it is memory related. If you can send me your tree I'll check it for errors.
Two things that you can try:
- Go to Customize -> Preferences... -> Max Script -> Memory - set it to 50MB or more.
- When possible work in "Speed edit" mode ([s] button in edit filters).
I'll check the undo system, script should not clear the undo levels but it happens.
The last problem - I don't know what causing it but the only solution is to restart max.

Great script - encoutering a few issues

I really like the script, not used it too much, but messed around with it, and will be definitely be using it to make trees for game usage, which this is perfect for with its options, actually looking forward to building up a tree database much faster than my previous attempts.

I have only held off using it much so far, as I am having a number of issues which make it unusable or tedious to use for anything intensive.
Using max 2010, 64bit. After some editing, closing edit mode, and building, going back to editing, I encounter the Maxscript garbage collection error, only indicating an error occurred while max was performing garbage collection.
With that, an error box with a code like x112.02.0059 (not sure if it is different on each occasion), and the options to 'try to recover and restart script' and 'close script'.
Hitting the recover option, turns up a Maxscript rollout handler exception, 'Type Error: Call needs function or class, got; undefined'
Close script works, and I can edit again, but it'll pop-up again when editing.
Sometimes, it causes 3dsmax to freeze, in turn making the whole system lock up for a minute.
Two other issues I am having is my undo levels, are erased when using the script and the errors occur, and when moving anything in the scene, even in subobject mode, they move right off centre from the actual cursor position. (Edit: this has been mentioned before, pretty much, when I move, scale etc, it does it in huge steps)
Not sure if its my copy of max, some settings conflicting.

I am very much interested in using the script a lot in future, as its pretty much what I have needed, easy tree creation, but directly in max.

Simple, and with great options.
Thank you very much!

leaves orientation

Hi Phil,
The orientation of the truck is always align with the world XYZ axis. This is the reason way orientation of the leaves looks wrong in your example.
For plants like this I suggest to uncheck Built [T] filter, set simple straight line for the trunk and make the shape of the first level branches like your current trunk.
See the attached image.

Leafs dont orient to parent if its the trunk


This script is awesome! However, I have a bit of an issue. Leafs that I assign to the trunk, don't take on the orientation of the trunk like they can do with the branches. Not sure if I'm doing something wrong here but its working on my branches. (see attached) I would like them to go evenly around the trunk, like they are on my branches.
I should perhaps also mention that they do go evenly around if the trunk is upright, but as I want it to go parallel to the ground it not working.
