I don’t know if undertand exactly what you need, I suppoused is the “Shape Traces” way, in multi trace, then filter the requested object by Class designed or compared in array (for example), is up to your goal. I hope it helps you.
So thats what i was searching for! I couldnt find something under traces cause they are called raycasts. I think as i understand this tutorial its pretty simple to implent in a quick and easy way. We see about that… thx
