Basically I want several objects to share the same shared material, only difference is that each object needs a different color multiplier.
Is their a way to do this without using different materials?
Even i was looking for something like this, but ultimately found that it was not possible. so i created material through script,
renderer.material = new Material("<code of shader you want>");
you can get the code for shader you have by opening it with script editor.and then you can set color using renderer.material.color or renderer.material.color
