Mirroring uv's on very lowpoly stuff?

Japhir

Hey guys,

There used to be a thread about how to mirror lowpoly uv's without having and edgeloop deviding the mirrored parts. You where supposed to put the uv's halfway past the edge of the unwrap, and then set your texture to "mirror" instead of the usual "Tile". Problem is that when I set it to mirror it doesn't fit at all anymore, was there some small step i forgot? I'm using max 9.

Here is an image explaining what i'm doing, above is without mirroring/tiling, below is with mirroring.

Try setting your tiling to 0,5

Japhir

thanks, i tried it but it doesn't work .

Japhir

Ahh got it
pure luck made me find out that if i set both tiling and offset to 0,5 it worked out.

yay .

Xenobond

Ahh, yeah. That's it. I've only had to do that a couple times when doing render to texture tasks. Couldn't remember all of the details.

Glad I could helps.

Interesting uv trick...
Japhir, is there any chance I can see how you've gone about laying out your uvs in the editor with the map displayed beneath? I'm just curious to see it

Japhir

sure thing KP, will make some images now. will edit this post later.

EDIT:
here it is:


and here is the model with the color blockin applied:


hope it helps

Thanks man, that's pretty fun.

Hey cool trick. How do you export this though? I guess the game engine supports it?

i believe someone pointed out that max and maya can mirror the uvs instead of tiling them, via a checkbox, though I can't recall where they are (and i use neither). Neat trick for those apps that don't have that option, though!

edit: I'm retarded. Didn't realise you brought that up in your original post. doh!

Eric, yeah, i'm pretty sure the engine or hardware needs to support this natively. The DS, for example, supports mirrored uvs in hardware.

Japhir

lol, no idea how to export it I don't export stuff, i just work in max. I'm not much of a coder/techy guy . (and i don't have any engines for stuff like that).
thanks guys!

Eric Chadwick

I didn't know DS did this, thanks LoTekK.

Xenobond

Nintendo 64 also had support for this.
