No, this thread is about Mario Kart DS. Make another thread

 Gericom: I made a test program to show what Mega-Mario says.
http://dirbaio.net/d/texscalefail.zip (NDS and source included)

Press Up and Down to change how many times the texture is repeated.
Run it in an emulator, and in the DS, and see the difference. The DS fails when you reach 16 repeats, while on an emulator it doesn't.

So you're limited to texcoords in the range of (-2048, 2048). Even if you use texture scaling.

Oh, that's the problem.

Basically, the only 100% working fix to this issue (preserving the texture quality) is to split large polygons into smaller polygons. Doing that automatically is likely going to be hard, so that task should be left to the modeller.

Actually no. If you have a polygon connected to the other one, and it uses the same texture, you'll get the errors, too. So you can try to copy the material and then if you think its enough, you create a polygon with the copied texture. The use won't see a difference, but in real you stopped the UV mapping of the texture.

What do you mean? That the software is being 'intelligent' and merging neighbor polygons when they have the same material?

Yeap. So lets say you have two traingles next to each other with the same texture. It won't stop the UV mapping They get merged to "one".

Probably yes, but we haven't found it yet.
We fix this right now by just creating two textures instead of one. Then the textures are different and it won't be "repeated".

I think I figured out my problem. Its my computer. I tried other application and some couldn't read some files on a directory. May it be a read only related thing that's causing my problem? They would get stuck on the loading screen. Will try on another computer.

EDIT: well I tried on another computer and the fixUV thing still doesn't finish.

Then you probably have a bad .imd?
Upload the imd please. Probably it works for me.

Download play never works with edited roms.

Or scaling the textures. Then the texcoords don't overflow.

Do you listen to what we keep saying? Scaling the textures does NOT work on the DS!

Unless you mean manually shrinking the textures. It can also work but you lose in quality.

No he means scaling in Sketchup (that actually works, but it will look more bad as bigger it is)

This is kinda like shrinking the texture. Then yes, it works, but it looks like shit because no texture filtering.

Here is the .imd if you want to poke around it. It worked for ray. Even thought I think it might be my computer, or some weird setting my win7 has. Im going to try on another version of windows...

Sorry, but the imd has the fault. Not your computer.
I haven't got the right to make this.
Look:


PS: ray, it can't be that it would have worked for you. Why should it? Try the same imd. I am pretty sure it does not.
