How to change the background and the texture of a part body while animating it?

I think this is not possible. Have you seen? Show me where.

greetings

see this sir.... it's wat m talking abt mr john's animation with a customized background. Compass PuzzleBox 1

Hello Abhijeet!
I think the video (animation) of john is made in keyshot not CATIA you can see that in the first second.

greetings

It is possible, but complicated:
- add a material to the body
- switch to the Kinematic Workbench
- add a Simulation
- select the material (in the select window)
- press "insert"
- press "edit simulation object"
- select the material
- press "edit"
- change the rendering properties
- OK
Now you've got two renderings stats in the simulation.
By using a sequence you can arrange/assemble the different simulations/mechanisms.

To remove any object or background in photoshop, try Magic wand tool, Lasso Tool or pen tool

Magic wand will be the easier one to do it, just select the background by magic wand tool and click. You get visible blinking lines then select more by holding shift once everything is selected and now press delete button and insert a new background.

Same way with pen tool just select with paths after clipping the area then hit ctrl+Enter blinking lines will be visible, then hit delete button then insert new image or background or something else you want.
