Firstly, all those blocks are what I need for my project, It was going to be a fighting animation. That's a massive building that i liked and I was going to credit the builder.
Secondly, I used the music in that video to play over 'Copyright music' I was listening to it on youtube in the background when I was recording the video. It's 'Best of NCS Music'. (NoCopyRightSounds)
It's not in the actual project if that's what you are talking about. And That was just a quick video I recorded and posted.
And so what you are all telling me, is to go find something slightly smaller and that I can import that I can still credit the builder, right?
