transparency for one color

Other Standards COLLADA

Hi,

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
transparency?

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.
