How to draw sprite graphic over specific objects?

Question

Hello everyone, and thanks for taking time to read my question. When it comes to simple scripting like in C# or Java I feel rather comfortable, but when it turns to being artistic and handling shaders, I simple go down.

I'm trying to accomplish a kind of "shadow" effect on sprites, which would only draw over specific objects, giving a sense of depth. I've tried a few different ways to do this, but nothing have worked. Underneath I've uploaded a picture, as an example of how the effect is suppose to look.

Example: alt text

When the shadow sprite is over specific layers or objects it's suppose to be drawn, but edge if it extents over the object. If you'd have any idea or solution on how to approach and or accomplish this, it will be very much appreciate it.

Regards and have a pleasant day.

@GnomenxD Is this what you are looking for?

Ship

Take a look at this example video 2D selective shadow .

You can not do this using SpriteRenderer. You need to use a quad with a transparent/cutout shader instead.

Here is how I achieved this:

3 textures 1. Ship 2. Tarmac/Ground 3. Grassy area

All 3 textures setting are set to advanced. The ship has transparency so "Alpha is Transparency" is checked.

3 materials (one for each image) 1. Ship a. Albedo is set to image of ship b. Standard shader c. Rendering mode - Cutout 2. Grassy area a. Albedo is set to image of Grassy area b. Standard shader c. Rendering mode - Cutout 3. Tarmac/Ground a. Albedo is set to image of Tarmac/Ground b. Standard shader c. Rendering mode - Fade

Here are the inspector settings for the 3 objects: alt text
