Sorry! I'm still not getting it. The code example you gave references
a movieclip on the stage (car_body_mc):
DAE_CarBody.materialLibrary.getMaterial("BodyDefault_png").material =
new
MovieMaterial(car_body_mc,{ precision:8, smooth:true,
interactive:true,
transparent:false,animated:false });
I want to set the default texture loaded with my collada to smooth. If
I use a movie clip on the stage as the texture for a model then I have
no problem setting that to smooth.
Here's a zip file with two models I have problems with (and the fla):
http://www.elyeball.pwp.blueyonder.co.uk/Problems.zip
I need the loudspeaker to have bothsides set to true and I want the
bumper to have a smooth texture. All your help is greatly appreciated!
BTW, I've just installed CS4 and now my project doesn't work at all! :-
( I don't know if this is a simple problem to fix?!?
