All the capabilities must be set *before* the object is compiled or made live. After that, if you have set the correct capabilities, you can change what ever you want.

Here is the code. Please let me know where i am doing wrong Appearance a3; a3 = shape1.getAppearance(); a3.setCapability(Appearance.ALLOW_RENDERING_ATTRIBUTES_WRITE); a3.setCapability(Appearance.ALLOW_RENDERING_ATTRIBUTES_READ); a3.setCapability(shape1.ALLOW_APPEARANCE_READ); a3.setCapability(shape1.ALLOW_APPEARANCE_WRITE); r= a3.getRenderingAttributes(); r.setVisible(false); thanks Venu -----Original Message----- From: Michael Pfeiffer [mailto:[EMAIL PROTECTED] Sent: Mon 10/13/2003 7:31 PM To: [EMAIL PROTECTED] Cc: Subject: Re: [JAVA3D] appearance problem The capability bits don't modify the Appearance itself! They only say what can be modified after the object was compiled. To change the properties of your Appearance object, try the different get...() methods to access the Texture, Color, MaterialAttributes etc. (please refer http://java.sun.com/products/java- media/3D/forDevelopers/J3D_1_3_API/j3dapi/javax/media/j3d/Appearance.html for all methods which can be used for getting and setting the different values).
