2.5D Game - How to cast shadows on invisble mesh objects

Adventure4Life

Hi,

I am trying to make 2.5D game using 2D background, 3D characters and 3D room objects.

i want to use the 3D objects only as colliders and for shading and to invisble there mesh in order to use the 2D background as a texture for them.

I have 2 questions:

1. how to cast a shadow on the room objects if there mesh are invisble?

2. do i have to crop an images of the objects from the 2D background in order to mask my character when he move behind them?

Welcome to the forum, @Adventure4Life.

Have a look at the 2.5D tutorial - both of these issue are covered as part of it.  1) involves importing a custom shader that handles this (this is a Unity issue, not one specific to AC), while 2) yes, you have to create cutouts of parts of the scene you want the player to be placed under.

In this tutorial, after adding the pillar mask the shadow of the character is not shown on it

only on the visible mesh like the floor

The mask uses a sprite, and the default Sprite shader.  You would need to find a new shader that allows the casting of shadows from 3D models onto sprites - but this is an issue on the Unity side of things, rather than Adventure Creator.

Thanks for your answer @ChrislceBox i will start looking for this specific shader, it is necessary for creating 2.5D games
