texture scaleing & stretching problem pls help !!

i am trying to model a quite complex model ( for me it is ) :headbang:
made up of about 200 hollow hexagonal tubes at diffrent lengths.
i made and loaded a psd texture file but on the top of the hexagonal tubes it sqashes the texture to fit and down the side it stretches it which dose not look the way i want it to.

i would like it to have the same affect as some brick walls which look equaly cosistand wether one wall is short and fat or long and thin.

hope im explaining my issue good enuf

tnx in advance for any help

ps im using maya 8.5, photoshop cs3 , (and z brush 3.1 which i dont have a clue how to use yet ) :p

note how the texture gets squashed and sretched acording to size which i dont want.. also i think i need to change the resolution of the texture somehow.... dont know how....so the the texture is repeated moreoften user added image

problem is that there are over 180 diffrent length hexagonal polygon tubes ....

id be 100 by the time id finish uv mapping each induvidual one :s

not shure but isnt there a simple way of texuring multiple polygons of difrent length.......?

I haven't really tried it out but I have done a quick preview just to see how it lays out the uv's, try out RoadKill, it's free to download and use. I'm going to use it on my next model, or the project I'm working on now just to re-uv map it. It seems to lay them out pretty good, and quick to.

I bet there is an easy way to do it, but I'm not that good at texturing too...

You will only be able to export what is in the top righthand box so you have to lay all your UV's out in the box.You can do this automatically but I would not recommend it ,just select all your UV's and scale them proportionally and then select each individual shell and move them around to fit into the top right square filling it as much as possible with your UV's.

In the UV texture editor under the Polygons menu set click on UV snapshot, choose the resolution your texture is going to be and then save the uv snapshot.
In Photoshop open the Uv snapshot and also your texture file and layer the texure over the uV snapshot which you set to screen mode to see it under your texture.Now you can play with your texture to your hearts content fitting it and sizing it to make the uv's,once done just save your texture file out and then apply it to your model in Maya.

I edited my message and like I said above you have to lay everything our in the top right hand box because thats the texture space, everything outside that box just gets a repeat of the texture.

ok what you need to do is make sure you have selected UV's so right click over your UV's and choose UV in the marking menu and then drag a slection to select all of them, now hit the R key on the keyboard to change to the scale tool, you should now be able to scale them using the center box so it's proportional.Once you have them scaled hit Q on the keyboard to change to the select tool and select a UV on one of the shells then under the select menu in the Texture editor click on select shell then hit W on the Keyboard to change to the move tool and move the shell into position in the top right hand area .Hit Q to go to the select tool and repeat for the other pieces until you have them all in the top right erea, you can rotate them to make it fit better if you want but the aim is to fill as much of the square as possible so don't scale them too small.
