Param wiring

Hi Corona!
Im tring to wire the coronabitmap uvwoffset.x to a point helper Z Rotation. My goal is to control the uvwoffset.x by rotating the point and the ather way also. Now,when i rotate to point,the U offset (uvwoffset.x) is changing& in the material slot the hdri is moving, but in the viewport its not.
When i use the U offset (uvwoffset.x) in the coronabitmap its working fine,but the point isnt rotating..
What have i missed?

I assigned point3XYZ controller to CBitmap’s uvwoffset and connection works in both way, however it fails to update viewport when point helper is rotating. I guess it’s a Max’s thing and there’s little we can do about it. I would be glad to be proven wrong, though.

When i wire the point helper to 3ds max regular bitmap U offset, it`s working both way and the viewport updating..also vrayhdri horizantale rotation is working fine…
So,is it a corona problem?

I did the same thing as Romullus, and the viewport bg is not updating here as well…
