Cycle a section only of texture

[[APS]Gnat]

How in O2 to you map onto a model a wrapping/cycling texture across a large area, but you don't want to wrap the WHOLE texture, only one section of your main texture.

example is a Ships Hull texture makes up 1/4 of my 1024x512 texture file, and I only want to loop that 1/4 area down the whole length of the Hull.

I've seen it done on a model, but wondering if its done OUTSIDE of O2 .... http://forums.bistudio.com/oldsmileys/confused_o.gif and it just imports ok into O2.

Sure, you could manual apply the texture head-tail-head-tail.... , but obviously each application has to line up with face edges and shyt like that .... too hard.

hmm... using 3rd party apps for UV is the best solution anyway http://forums.bistudio.com/oldsmileys/wink_o.gif
I can guess you can use tiling and then "merge textures" *.ptm script to get it into part of the bigger texture

if you want to do it in O2 and if I understand well your problem,
the easiest solution is make a seperate texture from your main one, apply it, then merge it into the main one again.

the problem you'll encounter is that the part you cut in the
main texture must be in a ^2 square/rectangle proportion
and same for distance to the borders.

your 1/4 example would work with this technique.

edit :
before considering using this method, in my knowledge even
the last O2pe version doesn't support texture merging, and i
f you export in old .p3d format to use the merging feature of
old O2, again there is a risk it won't work.
these info are just warnings not verified facts.

OK, thanks guys.
I've seen some discussion about texture merging and I have to say I barely understand the idea at best ..... sounds like more research needed on that subject http://forums.bistudio.com/oldsmileys/confused_o.gif

I was hoping it was as simple as defining coordinates within a texture map and telling O2 to cycle just that area across many faces.
