Specifically how mip maps work: If i load a 1024x1024 image into memory and tell it to make mip maps, it'll scale it down to make a 512x512 version, a 256x256 version, a 128x128 version etc all the way down to like 1x1 i believe and it will store all of those in memory. What you can do though if you are overbudget in memory you can specify how many mip maps to create, less mip maps = less memory used. Also, you could do something like in that 1024x1024 example, you can tell it to throw away the mips > 256x256. This will make the texture look more lower resolution but in the process you saved 4MB from the 1024x1024 image and 1MB from the 512x512 image so in total you saved 5MB of memory just from doing that. You might find some texture in the game that isnt really important (maybe its only shown in one place players hardly ever see or maybe it is only shown from really far away anyways) and then turn down the mips to get some memory back. This isn't the kind of stuff you'll likely ever have to deal with but might be good info to know. I think usually technical artists and programmers deal with this kind of thing.

I use Maya so I am trying to see what the best route is for possibly using normal maps. I am still discovering mudbox, and I don't know how easy it is to get my hands on that, and if it is something I want to integrate into my workflow. Still exploring that possibility... --- On Fri, 2/26/10, Larvantholos <larvantholos@xxxxxxxx> wrote: From: Larvantholos <larvantholos@xxxxxxxx> Subject: [project1dev] Re: Maps To: project1dev@xxxxxxxxxxxxx Date: Friday, February 26, 2010, 9:56 AM Its an nvidia plugin you can get from their website, it allows you to edit and draw on the maps, as well as create them within photoshop. You'll get a better affect create the map in 3d - if you get your hands on mudbox even just for rendering purposes it creates excellent normal mapping which in 3ds max compatible mode will let you use it in most other programs :) --- On Fri, 2/26/10, katie cook <ktmcook@xxxxxxxxx> wrote: > From: katie cook <ktmcook@xxxxxxxxx> > Subject: [project1dev] Re: Maps > To: project1dev@xxxxxxxxxxxxx > Received: Friday, February 26, 2010, 12:53 PM > Yeah I know mip maps are > different than other kinds of maps =) > > I was looking into getting a plugin for photoshop that > allows you to make normal maps from a grayscale image, and > the plug in specs talk about factoring for mip mapping for a > certain execution. > > Katie > > --- On Thu, 2/25/10, Alan Wolfe > <alan.wolfe@xxxxxxxxx> wrote: > > > From: Alan Wolfe <alan.wolfe@xxxxxxxxx> > Subject: [project1dev] Re: Maps > To: project1dev@xxxxxxxxxxxxx > Date: Thursday, February 25, 2010, 2:40 PM > > > > Yeah > > mip mapping is usually taken care of by the engine > although i think sometimes the artists can specify # of mips > for specific textures. > > Basically, in a 3d game, the video card has > to be able to render textures at different scales (as you > notice, when something gets farther away from the camera it > gets smaller...). > > It can do this one of 2 ways.. > > #1 - scale down the image on the fly every frame (this > usually either results in textures being scaled quickly so > that they are ugly, or results in frame rate dropping > because they are scaling the textures nicely which takes > longer) > #2 - Scale the image a bunch when it's first > loaded and store the scaled images in memory.
