Beginner texture question:

I thought, if i took object coordinates, the noise textures etc. would have different values so that the material doesn't look the same.

Unfortunately they look the same.

So it looks like i misunderstood here something!?

Alternatively you can use an Object Info node's Random or Object Index values to create variations. Here's a contrived example where the Object Index is used to control the W value of a 4d Noise texture while a random value is added to its scale to change the scale slightly.

W is often used as a "seed" in Noise textures. The downside is that 4d noise is computationally expensive, but you can use the Random value to randomize any parameter.

This has a slight advantage in animation: Using Position means that textures will "swim" as you move objects. On the other hand, if you want the swimming effect, then Position is exactly what you want.

Randomizing a noise texture with overkill

  • $\begingroup$ you are right, i just wonder why in my "special" case my solution worked....but it was a more complicated material from a library. But in the easy case i tried you are totally right! thanks! $\endgroup$
