Are effects rendered using rendering.draw_animation() and rendering.draw_light() expected to be synchronised?

If not, how do I synchronise the state of a random number generator? As far as I can see, Lua's math.random() only lets you seed it, but there's no facility for synchronising state.

Take a look here:

Also if I recall correctly you don't need to sync math.random(). It is modified for game use and uses map random generator.

Render objects are part of the game state, just like entities. If they weren't, they'd be disappearing on save load

Math random is deterministic and math randomseed it does nothing.

Ok that makes sense, and makes things really easy. Thanks!
