Quesa 1.8 broke my app; assertion in E3Set::Add() adding a kQ3AttributeTypeSurfaceShader

[Sean M. <se...@ro...>]

Hi all,

Up to recently I've been using Quesa 1.7 from CVS of 2006-03-28.  Now
I'm trying 1.8 and now my app crashes.  The code is:

=09TQ3ShaderObject=09shader =3D Q3NULLIllumination=5FNew();

=09TQ3PolygonData=09polygon=5Fdata;
=09polygon=5Fdata.numVertices =3D ...;
=09polygon=5Fdata.vertices =3D ...;
=09polygon=5Fdata.polygonAttributeSet =3D Q3AttributeSet=5FNew();

=09Q3AttributeSet=5FAdd( polygon=5Fdata.polygonAttributeSet,
    kQ3AttributeTypeSurfaceShader,
    &shader );

And then in E3Set::Add() (called by Q3AttributeSet=5FAdd) this assertion =
fires:

=09Q3=5FASSERT( Q3Object=5FIsType (
    setData.attributes.surfaceShader,
=09=09=09 kQ3ShaderTypeSurface ) ) ;

It crashes a few lines later.  I'm not sure if I built 1.7 with
assertions, but there was no crash then.

Is this not the right way to add a null shader=3F  Our goal is to add a
null illumination shader to a polygon object.

Thanks for any advice!
