Object avoidance

Learn how to make the effects avoid obstacles.

The pack uses SDF's that calculates object avoidance on the GPU. This results in it being very performant, but also comes with some limitations. Only one object can be avoided & only some effects supports it.

Creating an obstacle

1. Open Window → Visual Effects → Utilities → SDF Bake Tool.
2. Assign the mesh or mesh prefab of the obstacle.
3. Make sure the bounding box fits the mesh in the preview.
4. Bake & save the SDF.

Making an effect avoid the obstacle

1. Select your effect that has the Object Avoidance category in its Visual Effect component (e.g. Butterfly Flock).
2. Assign the SDF we creating in the previous steps to the Signed Distance Field of Mesh property.
3. Align the Mesh Bounding Box to the obstacle in your scene. Do this by copy-pasting the Transform of your obstacle.
4. Use the gizmos to fit your entire obstacle in the bounding box.
