Electroplating onto SU-8

Sputtering may not work as the Su-8 couldnot be
exposed to higher temperatures.So you can go with
electroless plating of Cr/Ti .Thats better. Then go
for the electroplating.

Cr forms oxide too.So you have tp take steps to remove
CR oxide otherwise Cr oxide is bad conductor and
adhesion with Cu will be a prob.
