3D Target Cursor Marker – Free Download

A simple 3D target cursor

No textures needed
Color can be adjusted
Just uses an animation clip
works with LWRP/HDRP/classic pipeline (material needs to be converted) – no custom shader
Includes a sample project on how to use it with e.g. a NavMeshAgent.

Simple example code

// Cache it.

FeedbackPointer _feedbackPointer = new FeedbackPointer();

// Initialize it.

_feedbackPointer.PreparePointer(_moveToIndicator, _feedbackPointerScale);

// Use it with a 3D position.

_feedbackPointer.ShowPointer(navHit.position)

Tested in 2018.x to 2021.x but should also work in older Unity versions.

Just an animated prefab with a single material and a script placing the prefab on the NavMesh.
