I'm making a laptop for The Sims 3 and I have one simple question:

If the default texture size is 256x256 can I make it more detailed by making the texture size to something like 1024x1024?
If not, how can I make the texture map more detailed? Thanks

You can change the size of the dds IMG's but you will also have to change the size of the mask width and height in the mtlsrcs. If you're changing the ratio of width to height (or changing the dds size significantly) you also will have to change the tiling or map to compensate for the distortion that results.

Both of these issues are discussed in the tips post with links to relevant threads here:

I think both issues are also covered in the S3 wiki here too.

Ah, I get it now. Thanks for helping!
