To get this working with the latest Xj3D loader you will need to call setCapabilityRequiredMap to indicate that appearance nodes need to have ALLOW_APPEARANCE_OVERRIDE_WRITE on them. And you will need to call setAppearanceOverrideEnable(true) on the appearances you want affected by the AlternateAppearance. Unfortunately we don't have an example of this in Xj3D currently, we just implemented the j3d capability bit override in M5. If you get a small demo working I'd be happy to check it in as an example to others. -- Alan Hudson President: Yumetech, Inc. http://www.yumetech.com/ Web3D Open Source Chair http://www.web3d.org/TaskGroups/source/ =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
