texture UV animation problems

[Keith W. <kw...@cs...>]

In Meshwork I have created and exported an object.  In my program I use 
pretty simply UV transformation to make the texture slide over the 
surface of the object.  Now, if in Meshwork I check the button for 
opaque or transparent, the animation works perfectly, but if I check the 
button for alpha, the program exhibits no animation.  The code is 
identical in these cases, only the object is being altered (and only its 
texture assignment, not the geometry).

Does anyone know anything about this?  What is a reliable way to get 
textures to animate?  Apparantly there are some detrimental bugs 
associated with UV transforming.

I have attempt to manually animate the UV coordinates by simply 
"pushing" the UV assignment of every vertex in the object at regular 
intervals.  This works perfectly at first, but then flips around starts 
sliding backwards periodically.  I think this occurs when the UV 
coordinates wrap around the end of the texture.

Any thoughts on this?

Thanks.
