That's it. I attached a sample scene (both in Max 2022 and .fp format).
These are the most relevant parameters:
- Gravity: 100% (it can be greater that 100%, if you like)
- Adhesion: 0% (Ivy is not attracted by the surface)
- Climbing: 0% (although is not essential, because Adhesion is zero).
- Death Distance: use it to define the maximum length of the climbing branches.
