Viewport and final are not matching each other.

You have to apply the scale on the object with displacement, then multiply the displacement height with the applied scale (i.e. 10 in this case).

I'm honestly considering to export every object with scale != 1 as instance even in final render at this point, because of tons of mismatches between render and viewport like this one.

What Covid19 remedy :lol:
More seriously this isn't a long term solution. I like the current viewport behaviour.

Wanted to make a Tutorial about it but this behaviour add a complexity layer we shouldn't have or teach to someone.

going to make the tutorial right now :mrgreen:

Now it is a mismatch between texture transformation displacement. normally it should be stretched.

final and viewport look identical to me, am I missing something?

yes you miss. i mean in the viewport displacement doesn't match the voronoi texture stretching. connect the displacement node to see if it match texture transformation.

My bad i didn't select the right mapping transformation mode (Should be UV not Global)

I think there's a bug here.
