Hi, I can't test this because I don't own the game, but does anyone else know if it's possible to use the unit sprites from Victoria 2 in EU3. Thanks.
You could download the victoria II demo and try for your own use at home. I don't know about army sprites but I tried to use some ship sprites from Vic II and they ran but their size scale was too big. I think their .xac files were compatible but I had to use the standard Paradox movement and idle files from existing EU3 units as the Victoria II ones generated errors about "smoke" being invalid.
If my memory is correct there was a eu3 DW mod that had some victoria II sprites and some one may have questioned if we are allowed to include in our downloads sprites from other Paradox games or even from the commercial sprite packs for EU3 DW. I don't think Paradox will allow this but I could be remembering wrong.
