Ok I would move camera in this time.

Maybe it's not a question but a reflection on the topic:
what happens with the HDR map, when the object is rotated together with the room and the light relative to camera?

in the graph editor, modifier tab, channel follower. This allows you to link one motion/rotation/value to another that is being animated.

I'm not sure I'm understanding some things here.

What is the use of your HDR here? An HDRI is used to simulate the environment something is in. This shot has only the product and the ground plane visible.
What is the value in this? I don't see that this does anything that can't be done by regular lighting techniques.

Why would you want to spin object, room, and lights instead of just moving the camera?

You say the channel follower is on, but what is it following? Is it following the rotation of a center null that is driving the camera rotation? Is the changing lighting what you have an issue with?

I think if rotate an object HDRI effect remains static relative to the camera?
If the camera rotates HDRI effect remains static relative to the camera anyway?
That because I have use non static image.

It works as expected, the problem here is we don't know what you need.

If you mapped the HDRI on the backdrop it will stay static to the world, that means if you only rotate your object the HDRI stays fixed, if you rotate the camera then the HDRI seems to spin because it's locked to the world.

Channel follower was suggested as one of the many ways you can change this behaviour in case you needed something different.

Much thanks, Danner! Now i have good tool - Channel follower & discover his opportunities.

I was recommended a good idea, bake effect to texture. Will to try.

In your case, I would make null, parent camera to that null, and then keyframe null rotation [email protected] and [email protected] Make camera target central object. Instead of trying to rotate object & environment map..
