POV and Alpha’s

All,

I am pretty new to POV – but – I think I have the basics down… I have been using it to take screenshots of a locomotive I have been building and the shots come out fairly decent…

Now that I have ‘alpha’d’ the cab window cutouts with double sided textures – POV has all kinds of problems with the shape… The surfaces are pretty mangled and it looks like a great deal of noise in the area of the cab… The rest of the model is rendered correctly…

Even the ‘alpha’d’ wheels look fine…

Any ideas ??? Do I have to do something special with ‘alpha’d’ textures and POV ???

Thanks…

Scott
