Ball trail (trace) on golf course surface for Unity 3D

Main Goal

We need to get a special Unity 3d visual effect which will display the trail effect on golf course surfaces. This effect must be prepared for use and have all the necessary settings and resources. Ball trail effect should work on low-end devices HDRP (PC), URP (Mobile) render pipelines and give a good level of quality.

Main features:

1. Display trace of a golf ball rolling on different types of surfaces. Following shading on top of the surface texture.

2. The ball surface trace should be PBR with HDRP and URP types of shaders or bout platfor shader. Shaders must have color texture, tint alpha color, normal map.

3. The trace should spawn step by step behind the ball and disappear after a certain time in order to create the effect of the gradual

disappearance on the grass surface.

4. Ball trace will have allays visible state for golf bunkers surface.

5. This effect must have C# script controller to spawn and set visual parameters.

6. VFX has different types of visualization for golf course surfaces.

7. Effect shader should have flowing interface in material: color texture map, normal texture map, smoothness parameter, specular parameter, tint color, tiling and offset.

8. Scrip controller sets all parameters for controlling effect through the interface, has all the necessary states and settings: surface type, trace visible time, trace effect power, trace width.

9. We should be able to set up all needed VFX parameters clearly.

Additional description

When a golf ball rolls on a grass or other surface, a specific mark remains. We need to simulate it. When the ball is hanging on the grass, we see its color change, this can be achieved by creating another surface on top of the surface with a special shader. On the grass, the trace quickly disappears as the grass restores its shape. At sand, the effect remains constant. The effect should be as unique as possible and not depend on additional parameters of the Unity scene. He has to work on render Height Definition Render and Universal Render pipelines. We will evaluate his work on the test scene that you will prepare.
