LIFO Files

(1/3) > >>

akatonbo:
All right, I'm stumped, and I know there must be somebody here who's sufficiently into the squishy guts of actual content creation and editing to be able to give me a clue. (Ambular?) I want to make some skintones. I want to start with the highest quality Maxis images I can get my grubby little hands on. So I've located the LIFO files in Sims08.package and so on, but I do not know if there is a way or even a reason to 'Extract' the 6LI files and get them into some format I can edit, or if using 'Export' to PNG is the best I need to do or the best that can be done, and neither Google search (sims 2 lifo, among others) nor the limited searching I can do here (searching on just 'lifo' brings up every thread in which California is mentioned, so I had to use 'lifos' or add extra keywords) has brought up anything useful.

AFAIK, you just extract them to .png.  If there's a better way to do it, I've not come across that information.  Use the biggest ones in there (can't recall if that's the 0 or 1 files offhand.)

LIFO's seem to be a bit of a mystery all around; I'm not sure why they're even used, since they appear to give no obvious advantages over regular TXTR's of the same size and resolution.

Works for me, then. After all the to-do about using actual LIFOs when extracting Stories objects and so on I was expecting something more directly involving them for the best quality recolors too, but then couldn't find a thing. The PNGs are clearly very HQ anyway and about 1/3 the size, plus SimPE gives them meaningful filenames already, so I'm all for it.

wes_h:
I was never able to get LIFO files to link to a scenegraph as LIFO files. They appear to be the source image for the mipmaps used in the scenegraph, that is the TXTR files, and the game will accept TXTR mipmaps with more levels and a parger size, allowing greater resolution characters. But you have to extract the LIFO image and then remake the new mipmap texture from that.

As Amber said, always draw on the largest ones, because you can still reduce resolution later, but if you edit the lower resolution ones, they will not look good as good in a larger resolution.

I always use the LIFO's when working with skintones now.  They're much better-quality than the crap images BodyShop turns out.  In fact, Bodyshop is best used only to create a new, working clone of S4 (as I have heard that clones of the other default skintones sometimes suffer from texture issues,) into which you then import your modified textures using SimPE.  For best results, use DXT5 or even Raw32 compression, especially for darker skintones.  (Just make sure to Compressorize afterward or you'll wind up with ginormous files.)  XD
