⚠️ Limitations

• Individual kelp instances cannot be removed at runtime. You can remove or disable a kelp renderer to achieve a similar effect.
• Individual kelp instances cannot be added at runtime to a renderer that is already rendering kelp. However, you can create a new kelp renderer to add additional kelp.

👉 If you need runtime add/remove of individual kelp plants, this asset may not be the right fit.
