Question on transparent camera transformed objects.

[Peter M. <Pet...@mi...>]

Hello all,

Sorry to be bugging the list but I would like some help on a problem 
with transparent camera transform objects.

First a little background, I am trying to simulate the selection box 
used by Apple in Preview, that is one white box then one black box and 
finally a light gray transparency elsewhere.

I have setup all the objects needed to create this effect, including 
four polygons with; an attribute of diffuse gray colour ( 0xAFFF) and 
an attribute of transparency colour ( 0xAFFF ) and no other attributes.

Now the problem, as the camera rotate around the polygons colour 
changes. The reason is that the polygons are real 3D objects in Quesa 
space so are effected by the sun light. ( tested by turning the sun off 
e.g. the directional light ).

We normally overcome this problem by submitting objects before the view 
light style is added but as the polygons are transparent this trick 
does not work.

Any ideas on overcoming this.

Is there an attribute that can be added to stop direction, point and 
ambient light data being mixed with objects that have transparent 
colour attributes?

Thanks in advance for any help.

Peter.
