Learn how to use the IvyGen add-on in this tutorial by Filippo Veniero.
Vegetation and plants can turn a flat image into a successful work, but created by hand, realistic ivy can become a nightmare even for an expert 3D artist. Luckily, we can use a Blender plug-in: IvyGen. This plug-in implements a procedural system that produces realistic ivy on our mesh. It's free and very easy to use, you can use it in Blender or as standalone software, and it is available here. You'll find a standalone version for Linux, MacOS and Windows and a lot of good textures. This isn't a biological simulation of growing ivy but it produces complex and convincing vegetation.
