FYI: I use six year old mac book (not pro) with bog standard drivers and everything works fine for me.  I am relatively new to xith3d but I am doing some fairly none-trivial stuff with it.

Thanks for the reply.  The other Transparency Attributes all seem to work fine but dont suffice for what I need (see below).  I'll keep trying, maybe I need to read more about how it works in opengl and then backtrack through the code.

I have a series of Quad Array shapes and want sections of their texture to appear 100% transparent, like holes have been cut in it.  In blended mode, whilst it works, I get an xray effect where I can see straight through other sections of the same shape, which I believe there is no work around for.  However, I think screen door mode should allow this as the transparency is done in the opaque phase and I am happy to sacrifice some quality to achieve this. 

Hi,

Does anyone have an example of using the BlendMode.SCREEN_DOOR setting as a transparency attribute?  I have tried a number of different permutations but can't seem to get it working, my shape is always rendered 100% opaque. 

I am using RGBA colours for the shapes vertices, with a range of different alpha values and I have tried setting the TransparencyAttribute's transparency value to various values to; all to no avail.

I am relatively new to xith3d and very new to these forums so I apologise if this is a stupid question.  Please ask if I need to provide more information.

Many thanks in advance

Steve
