So I can start using PNG as my staple file format instead of JPG?
That would be wonderful, big fan on lossless compression =)

oh and btw some more tips for whoever doesn't know it (:
Our game supports lots of different file formats (jpg, gif, bmp, png, tga, etc
etc)
some of these file formats are smaller on disk (.jpg is the smallest) but when
they are actually used in game it has to decompress them into memory so all
file formats use the same amount of video memory (ie if a file is small on disk
that doesnt mean its small in memory)
Because of this, even though jpg is the smallest, it tends to add artifacts to
the images due to the aggresive compression which can make art look bad
sometimes (as im sure you guys have noticed before) and it doesnt really give
us any benefit other than being smaller on disk.
Anyhow, from our options, it seems like PNG is the best image format because
PNG uses lossless compression - which means it compresses the art to make it
smaller on disk, but your art is NEVER changed by the compression scheme, so
it'll be pixel perfect in game to what you actually saw in photoshop.
Also, PNG has an 8 bit alpha channel so you can specify transparency and semi
transparecy which the game fully supports.
So yeah, you can use whatever image formats you want but just wanted to let you
guys know that PNG from a technical POV is a really nice format (:

I don't recall saying larger textures were better???
I remember asking what the limitations were as to make sure I wasn't overdoing
it.
I did mention that I have been trying to make efficient UV maps by including
all the pieces on one so that the tech side doesn't have to juggle a bunch of
different maps for one model.
Like when they make character maps, its usually just one painted uv map if it
is done well.
Thanks guys, that my clarification, sorry if I added some confusion.

Thanks a lot for this detail of info. did not know a drop of it, heh. I
thought Katie said larger texture is better so I have been resizing them
larger. Ill give this a go and see how well I can get it to come out!

Nice hammer Hanaan!
It looks very viking like (:
Unfortunately the milkshape format doesn't support bump mapping so, how we have
to do bump mapping is...
#1 - check the bump map texture in along with the normal textures
#2 - when the model goes into the game, Kent or I has to manually set the bump
on the right part of the model
So yeah basically if you can check in the bump map texture too and say which
part of the model the bump goes on (im assuming on the stone part, not the
handle!) that would be most helpful (:
Btw great job centering the model, that's perfect!
The next peice of technical feedback i'd give you is i notice that on the
hammer, the woodgrain for the handle is a 2048x2048 texture and the texture for
the stone part is 2048x1024.
The game uses 32 bit color so that means the woodgrain handle uses a 16MB
texture and the stone part uses an 8MB texture, totalling 24MB just for
textures for this one hammer.
When you are making a game, you may only have 32MB total texture memory for ALL
of your props in a level total so you can see something like this would eat up
almost all of your texture memory (which is no good!)
Because of that, when you model an object, you want it to use the smallest size
textures you can use where it still looks ok. For instance, i'm just guessing
but for a hammer like this, i'm betting two 256x256 textures would be more than
enough detail. Two 256x256 textures combined come only to 128KB so as you can
see that would save a BUNCH of memory.
Anyhow give it a shot, see how small you can get the textures where the hammer
still looks ok. Keep in mind too the size of the hammer so you can kinda get
an idea of how it would look in game (ie if it's small in game you dont need as
much detail).
Also if it helps, i can toss the hammer into a map for you so you can see it in
game, just let me know (:
Anyhow great job on this peice, it looks really nice!
