Unwrapping this object

Recommended Posts

Can anyone tell me the best way to unwrap this simple shape? It couldnt be any more basic, but no matter what I try I end up with a mess. There must be a way of flattening it out without separating the UVs into 4 or 5 different islands.

 

Thanks

Frontal mapping (top view) + LSCM relax ?

Could maybe do with a little straightening out, but it was 2 clicks to get this far...

  • OK, thanks. And if you had a cube of these objects? Do you make cuts and relax it twice?

    No, then I'd map it as cubic 2, then relax once I think...

    Actually, no scrap that - that gives me big problems in R20 ! We have possibly found a bug there, because cube 2 is NOT doing what I expect it to.... and nor is Cubic if we look closely...

    Could you try these (no relax) in R17 and let me know if your results are the same ?

  • Sure. Did you cut seams in it, though? I ended up unwrapping it by literally highlighting all the UVs on each face, one by one, tearing them off and then terracing them back together. I couldnt find another way. All the projection methods just split my model into  a million useless bits.

     

    Edit: I should say this was my object, a crate I have been trying all day to model, advice on UVing this quicker next time would be welcome.

     

    Unwrapping the simpler object in R17 gives me exactly the same result as you.

    I didn't cut seams, and I shouldn't have had to ! Cubic projection should negate that, and in fact it did - look at my Cubic 2 map above - clearly the seams have been cut, it's just what's inside them that is wrong - we have overlapping UVs polys there, and no reason I can see for that to have been the case. I might not be as expert at UVing as I might be at modelling, but I'd hope I do know what a Cubic 2 map should look like, and that what we are getting isn't it. Further investigations are underway...

     

    As far as I am concerned one of the cubics, and a single relax should have been all we needed to do there, but had that failed for me, I would have done the same as you, and done them individually, stitching them back together afterwards.

    Huh, interesting. I think I remember always having problems with 90° angles and cubic mapping. I'm not too sure though and I can't really test it, only have R20 installed.

    Well I just found an interesting solution, which will do it in one move, but I think it just confirms that this is a bug with cubic mapping.

     

    If I get the cube as before, but UV map it with Cubic 2 BEFORE I do any of the Extrudes, then when I subsequently do them the UV map stays correct and responds to relax as I am expecting ! (R20)...

    I don't yet understand why that might be...
