Hi I was just wondering if you don''t set up any projection (IE Ortho or Perspective) what does DX default to? Cause I still see my textured vertex Secondly why when working with 2d in ortho projectio is it necessary to switch of the z-buffer? Thanks Talib

Try, try and fucking try again.

I''m not sure what DX default to, but when when working with an ortho projection you don''t have to switch off the z buffer.

DX defaults all internal matrices to Identity.

Don''t think so.
