Ivy Generator is a small tool that simulates a virtual ivy growing by itself. This procedural system enables the ivy grows from one single root following different forces that are predetermined before start the growing process. You can set a primary growth direction, random influences, an adhesion force towards other objects, an up-vector imitating the phototropy of plants, and finally gravity. This simple scheme reveals that the goal was not to provide a biological simulation of growing ivy but rather a simple approach to producing complex and convincing vegetation that adapts to an existing scene. The ivy generator imports and exports obj+mtl files.
Start with 3ds Max:
Step 01. create a geometry you want to put Ivy plant on;
Step 02. Export the geometry in wavefront (.obj);
Then, go to Ivy Generator tool:
Step 01. Open Ivy Generator and click on “import obj+mlt” button and choose the geometry that you’ve exported in wavefront (.obj) format;
Step 02. Now, you need to set the place the ivy plant will start to grow. Select the area of the geometry you wanna the ivy grows and Double click;
Step 05. Press “grow” button with the default settings or try to play with the settings to customize the way that your ivy plant grows;
Step 06. Before to press the “export obj+mlt”, make sure to press “Birth” button;
Finally back to 3ds max:
Step 01. Import the geometry you’ve exported from Ivy Generator Tool.
Step 02. If you’re not seeing the material in Material Editor go to Material/Pick Material from object…and pick on the ivy plant. Now you have the material added to you material editor.

Step 03. Load the Opacity Maps, for each leaf.
Step 04. Finally, render out your scene.
