I built this with Geometry Nodes to make it easy to add objects on curves easily. This is customized with a fast and light procedural algae. With this you can use the curve drawing tool to add algae to anything you need.

Key Features:

• Procedural Algae Shader: Simple and customizable shader for realistic algae.
• Randomization Controls: Adjust scale, rotation, density of leaves, and deformation for variety.
• Versatile Node Tree: Adaptable node setup can be used for other objects as well.
