This is my second question and one I have been trying to ask for a long time on the YouTube channel.
Please have a look at this brilliant Videohive project: https://videohive.net/item/hero-animation-toolkit/20005694
It's not new and for a couple of years now, I have been asking the author periodically if it was possible to customise the project so that the logo on the chest of the superhero can be changed. So far, the author has said no. I feel that's something that really limits the use of the project. If you look at the video demo, you will notice that the character has a yellow and black circle in the middle of the chest. That cannot be replaced or customised. For example, if I wanted to replace this yellow and black circle with a superman logo, I can't.
So I had a look at motion tracking, and although I cannot do it yet, I am pretty sure it is not difficult to track the yellow and black circle and put something (a logo) on top. But what completely throws me, is how that superimposed logo on top should react to 3D perspective. Imagine that the yellow and black circle is motion tracked and a new logo superimposed: when the character is turning around, the logo should also turn and eventually disappear is the chest come out of view. And I don't know how to do that.
When I asked this question on your YouTube channel, I asked whether you already had a tutorial that would cover this issue. I had not found one, but if there is, please just point me in the direction of the relevant video.
All my thanks
