Welcome to Ivy Studio, the procedural Ivy and climbing plants generator that focuses on the creation of realistic environment adaptive vegetation. Ivy Studio generates Ivy and climbing plants using the colliders in the scene as a base on which to grow, climb and adapt, and can be used to create very optimized Ivy at runtime.

You can create the Ivy at both design and run time, create your ivy in editor and then grow it in the game, with a deterministic ungrow option that will recreate the Ivy exactly as placed in editor without the need for saving it directly in the scene, for minimal scene size.
