Hi Admin,

I did a small test, link shown below,
http://www.gtnconcept.com/mms9402/kai/cube_mod/cube_1.htm

User can type into values to change the apparence of the object (xscale and opacity) and get feedback when they drag the object.
The problem is I can not change the opacity.

What's wrong with my code?

Thanks for your helpSmile

Hey Dude,

To answer your question here and other places in the forums, try refering the XML code reference available at the Viewpoint Developer Central...
http://developer.viewpoint.com/dc/xml.shtml

I am sure you would have many questions answered.

Cheers,
Anup

You are doing vmp.ExecuteVETScript but you don't have any VETScript in the mtx. You have a VETScriptInterpreter defined in the MTX, but no VETScript code or VETScript function in the MTX which is what ExecuteVetScript is intended for.

Please refer to the VETScript documentation in the VMP 3.3.0.29 release notes pdf to learn how to insert VETScript in your MTX file.

Regards
