Mine is complete right now (fields, combats, worldmap), but i'im doing a full game trough to find bug and optimise filtering (because ingame rendering is not alway the same than picture rendering depending how much the game zoom the picture).
It's a long process to do but it'll ensure the best result a can do.
So maybe one or two months.
I'll also wait the AlphaAtlas tool to check i can do a better job on videos, can take some time too.
