Hi,guys,
I am trying to build a digital asset here,It's a asset inside shader,I mean it's at vex builder level.
And now I want there to be some parameter which link to a rotation of an object level camera.
Because the rotation keep changing,so I must like write a expression for the parameter of the DA.
And here is the problem,it seems that I can't write expression at vex builder level,it does not update.
I know I can promote parameter to shader level,but I do want to keep it at my digital asset which is at vex builder level.
So,how can I get that changing data and make it work for my digital asset?
I did some test,maybe someone can check my test scene(houdini14) and help.
Thank you guys.

the only way is Promoting get_cam_rot parameter for your digital asset , then link Camera rotation to this parameter out side of the VOP Network.

in the VOP Network we can't use dynamic valus (such as expressions , keyframe) and etc. for doing that we should Promote these parameters.
