I was wondering what would be faster. A model with one 512x512 texture, or a model split into 2 or 3 256x256 textures? With the new MED either is possible so I had this Q in the back of my head for a little while now... apoligies if this has been answered before and I missed it.

256x256 textures run the fastest from what I've read. 256, being 2^8 and 8 being a power of 2 (2^3) is the likely reason.

NO, one 512*512 texture will be faster. This is because using seperate textures on one mesh means that it has multiple subsets, this means multiple render calls, which is always going to be slower. This will be more noticeable the more entites you have.

I'm thinking that a single 256x256 texture will run faster than a single 512x512. However, multiple textures of a smaller size will run more slowly than a single texture of a larger size. Sorry I didn't state that clearly.

Ok sorry i misunderstood you.

2048*2048 really isn't a good idea, Ello. Send it to me and I'll see if there is anything I can do to optimise it for you.

well, i already know how to optimize.. creating single textures for each building will do it. but thats a lot of effort;) and for this i need to find a lot of spare time. anyway, thanks for your offer:)

Thanks for the explanations guys. And G'luck with your efforts Ello.

When I get home tonight I can build a small batch file that will add the option to split a file in the right click menu if anyone is interested. Shouldn't be a problem, I don't think anyways (which is usually MY problem )
