Unique UV textures 2004-05-06 - By Bernard Lebel
Back
Under the uniqueUV projection node, you have an operator called PolyPackUV.
Open this, and change the target resolutions to the resolution of the
output.
There is currently a bug in XSI 3.5.11 that doesn't save these values, so
you have to freeze the projection to retain the PolyPackUV settings (fixed
in v4, of course).
Cheers

meshes which I have had to optimise/cull faces on to run in realtime.
However after doing this whenever I apply a unique UV texture projection
(for rendermapping) I end up with poor UV coverage on the texture -
i.e.there is a lot of redundancy/unused pixels in the texture.

then half the texture is unused. Is there a way to reset the UV co-ordinates
automatically so that the whole, or at least most of the texure space is
used for those 3 sides? I cannot do this manually because of the number of
objects involved and the time limit!
