Unity - Shader Graph - Want understand difference between Object and World Position

I am new in world of shaders, and I don’t find good docs of shaders explaning line by line how shaders works, so I did the following shader with Position OBJECT and move 10 points in X axis:

1111×771 57.7 KB

So in Scene view I can see the GameObject is 0,0,0 but the mesh is 10,0,0. That’s correct:

1761×715 89.5 KB

And if I move the GameObject always the mesh is rendered 10 points away in X axis from the real position of GameObject.

Now I change the Shader, changing Position Node to WORLD, and I back to Scene view, if my GameObject is 0,0,0 the mesh is rendering in 10,0,0 but if I put the GameObject 10,0,0 then the mesh in rendered in 30,0,0 and if I put the GameObject in 20,0,0 the mesh is rendered in 50,0,0

Why this happens?

Ok I found the answer. If I put the object in 10,0,0 and use World Position in Vertex Position, the vertex go to 10,0,0 away from the real object so the position of vertex is 20,0,0

Two more notes:

  1. This happened because you inserted world space coordinates, meanwhile master stack by default expects object space.
  2. Matrix multiplication order matters, so in future put matrix into “A” slot.
