programming flash
1

i have a movieclip which containes image and textfiled and its drawn into a bitmap.
then i apply 3d rotation to it and after the rotation, text is quite blurry.

i found this thread:


but i dont understand how to apply senocular solution.

i also tried reseting matrix 3d but it didnt make a difference:

savedMatrix = mc.transform.matrix3D;
mc.transform.matrix3D = null;
mc.transform.matrix3D = savedMatrix;
