transparency for one color


I need that the texture material is fully transparent in its white pixels
and non-transparent for any other color. How do you sugest to do it?
It is possible to use an appropriate combination of transparent color and

Thanks, best regards.

This sounds like a case where <transparent opaque=“your_mode_here”><texture> is used.

To key on white in the common profile, you need to either: Use opaque=“A_ONE” and process your texture image into an RGBA where all the white pixels have a transparent alpha value, or use opaque=“RGB_ZERO” and add a <newparam> or <extra> element that activates an appropriate alpha test in your renderer.
