i have a png transparent texture, and im using EMT_TRANSPARENT_ALPHA_CHANNEL_REF as the Material type.
after im change the antialias in the device creationparameter, and set the material antialiasing to EAAM_ALPHA_TO_COVERAGE
on my AMD Graphic card all fine, but when i test it on Nvidia :
the mesh become solid. the transparent area become just black, just like im not using a transparent texture.
any idea, what should i do ???
