Bump Node on road object. Not showing up. It's driven by a baked image sequence of .exr files.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
I"ve sent file that works file (2.81) and the file that doesn't work (2.83). Just render the good file in Cycles and see the bump affecting the surface ripples in (puddles). Do the same thing in the fil that doesn't work (2.83.5) and the bump effect is missing.
