It is performance costly to make normal map animations?
I've created a jelly effect by alternating the normal map by a set of 12 different images... It looks fine but, I don't know if this is costly for the performance.
Thanks in advance for the help.
Did the very same thing with bump maps on a bark texture, looked very much like tripping... I'd say the cost depends on the size of your normal maps. What I did was very costly : switching between 12 high res bump maps of the same texture, not something I'd do on mobile for example.

Rendering speed is the same as before since only one gets rendered per frame. (Assuming you just change the material between frames.) You need 12x the (video) memory, tough.
