Aright looks cool. I will try this when I will have the time this weekend!!
For now I tried a simple Boole but my object have to many mesh. It take about 30 seconds to complete the task and I have a bran new iMac 27″ so..
What I tried today is simply put the object down in the foam surface until the middle. It works but if I want to render the object outside the box then the foam surface will be flat with no cuts in it. This is not the best.
I’m very happy you understood my request because I wasn’t sure if I was clear enough as english isn’t my primary language!
I’ll get back to you after trying this plugin! ???? C4D should consider integrate this kind of selection into their next version.
Oh and thank you so much for your very great details. Its more than appreciated
