Hi,

i took the example Intermediate_TextExtrusion.fla as and wanted to
have a texture on the text,
but it went out like this:

how can i make that work?

that´s about what i did:
material1 = new BitmapFileMaterial("earthmap1k.jpg");
textfield1 = new TextField3D("Impact");
textfield1.material = material1;
extrudeMesh(textfield1, 1, 2);
