I'm having a problem with my textures.  Its not the texture its the way the mesh is assembled... and it's driving me nuts because I can't figure out what I'm doing wrong.  Here is a link to a screen capture of the issue.  I am attaching the file as well.  Render it, you'll see the problem quickly.  By the way the file I attached is a zip file.

Thanks in advance!

First off some housekeeping - pls take care to post in the right section - here that is Textures / Materials (I'll move it there now for you). Also please use the cafe image upload system to upload pics rather than linking to them externally.

 

What you are doing wrong here is using a mapping mode (Cubic) that is not appropriate for that object. Cubic, as the name implies is best suited to objects largely comprised of planar surfaces on X, Y or Z. Your object has almost zero axis-planar surfaces - all its faces are at angles of very much not 90 degrees, so you force the renderer into guessing which of the 3 planar directions of Cubic to assign, and its decisions will not usually be the right ones. The bad news is that none of the standard projections will texture this well - really the object needs to be properly UV unwrapped.

 

If you do that, you'll get a pretty decent result despite the horrendous topology...

Or you could use this one I did for you...

    Thank you so much.  I apologize for failing to place my items in the proper locations.  Thank you so much for the wrap.  I honestly don't know how to wrap something.  Every tutorial I've found uses a cube.  And I can't wrap my head around it.  Sorry for the pun.  Honestly I've tried watching those tutorials at least a dozen times.  Every time I suck.  I truly wish I could learn how to do it so I can add effects in photoshop.  if you could help with this too, I'd buy you a beer!

     

    By the way the texture didn't accompany the file.  But thanks.  I'm going to dig into this part of the forum and see what I can find to help myself as well.  Again thanks a million!

    No I didn't include it knowing you already had it, but I did forget to warn you that you would need to relink it in my file :) I take it you got it loaded it in the end ?

    People tend to fear UV mapping, and it does seem daunting at first but once you understand the principles involved and have some practical experience with the tools it doesn't take long before you are comfortable doing it, and can unwrap pretty much anything.

     

    I looked at your rock, and decided I would place 1 big seam along the middle, and then unwrap it frontally from both sides of that seam, if you see what I mean.

     

    The UV mapping tutorial that really unlocked my understanding of it was this one, which you may have to watch several times, but is absolutely telling you what you need to know, and the thought process behind successful mapping.

     

    Anyway, hope that helps...
