Edge joins on Textures
|There are a few
tutorials on this already, here is my take on the subject. Some textures
have inherent seams and so they do not cause a joining problem. The
classic beach ball is an example. Some textures are meant to be smooth and
continuous. Lets start with an example of what we do not want to do:
As you can see the left and right edges of the texture get joined up when
they are applied to the mesh, if they are not made to match then there will be a
"seam" on the finished object.
test texture may make the problem clearer, in the process of applying the
texture to the object the texture is wrapped all the way round so the left
and right edges join up. Actually on the innertube the top and bottom
edges join in the "hole", but as its on the inside its not so
obvious, and a visible seam is more forgivable.
|In this next
example the fill starts and ends on the same colour so the join will be
smooth and will not leave a visible seam.
is to paint over the seam. To illustrate this I'll start with a semirandom
"blobs" texture. The edges do not join up so inevitably there is
we swap the left and right hand halves of the image, putting the seam in
Then we just paint over the seam to smooth it out.
Version with the seam visible
Version with the seam painted out. Its a small change but a big improvement.
