How To Rotate Object Not Camera with a Static Background

Ok…so you want to rotate an object with an image plane that is always the background.

I wouldn’t recommend this approach if you are using an Orbit camera as its counter-intuitive and will cause the user to probably get confused as far as how to navigate.

However, in the example kdv77kdv provided the image plane is linked to the camera…so you get a static background that you are requesting. However the movement is still the camera orbit not the cube rotating.
When you get the cube to rotate, the rotating the cube will not change the orientation, or rotation of the background HDR.

So…lets say our object is a cube that we want to rotate. This could be a group of objects parented to an empty…etc. But we will just keep it simple with Cube as our object.

Start with the Event Puzzle “when dragged over”. Change the selected object to “Cube” in this example.

From the Objects Puzzles insert the “change object local positon” puzzle. For this puzzle replace the Object with Cube. You can use either a vector input or use the standard x y z values. For this test, use the x y z and enter .2 for any of the x y and z or any combination you choose. You can adjust the number as you desire.

Thats it..mouse over the cube and drag…..the cube will rotate.

I tried linking the plane to the camera and that worked. However, the camera still rotates which is not what I am after.

but it looks like the model rotates if the “static” background is large enough ))) and the rotation is along two axles. the puzzle drag-rotate works only along one axis…

You can:

– parent your lights to camera.
– set your emmission on your image plane high enough that it is not influenced by the environmental map
– you can modify the image planes object properties to not receive shadows
– you can add a value node to the world texture rotation mapping node and rotate it based on the rotation of the camera.

I am sure there are others
