I want to know how an animated object moving on a plane could leave a mark on it.
In the exact way shown in this video https://youtu.be/cUsXyimUw6o?t=97 from 1:37 to 1:45
I need to explain how a cleaner product cleans the floor.
I want to show the area where the machine is cleaning.
I want to mark the floor where the machine passed through.
How I can do it?
In post-production for sure, but if possible (and if it's convenient) I want to avoid other softwares. I would do it on Blender.
Thanks
