Hi all!
Right now I`m learing FFX, and I noticed I can set an expression in Obj/Src to Temp. fuel or Smoke Amounts.
The problem is I cant figure out what to get as variable - something that changes in time (eg. time in seconds or miliseconds).
Or maybe I assuming wrong how expreesions actualy works.
By me it should iterate every voxel every frame and set to voxel whatever I set as an expression (eg. temp).
I couldn`t find any info on google.
Maybe someone could redirect me to some documents, tuts, or simply explain how expressions work (eg. how to set up expression to temp as sine wave - from -300 to 300 in 100 frames with 25FPS)
thanks
