Uniformly spreading a texture across multiple objects
Hello, what I am looking to accomplish is having one texture appear over the course of a number of objects uninterrupted. For example in the image below the hexagons are my tilled objects and for the sake of this question the orange shape is the texture I want to uniformly spread across the objects.
There are hundreds of these hexagons in my scene and they all need to remain separate yet appear as one. Having many material instances with different offsets leads to way to many materials in the scene so I was wondering if anyone had any other solutions?
3 options come to mind:
Use worldPos in your shader to apply the material in world position
Use screenPos in your shader to apply the material in screen space
Write a script to combine the UVs of your hex models and then apply material in (shared) model space
Which is best depends on how your game scene is setup. You can find details of 1 and 2 at http://docs.unity3d.com/Manual/SL-SurfaceShaders.html. For 3, look for the MeshCombine script in standard assets.
$$anonymous$$y hexagons need to work independently of each other and thus I think option one would work the best, thanks for the input, I'll play around with worldPos.
By updating my shaders to use worldPos I solved my problem, thanks for the help. For anyone else trying to do this and having some problems, here is a simple tutorial I found that helped me out. https://www.youtube.com/watch?v=s79Zu0F8fuY 
Hello man, I just came to that problem that I need shader like that, can you share it with me? @element271
