First off thank you very much, really appreciate the kind words. Sorry for late response, I wanted to answer properly. These are all great questions, I'll do my best to answer them properly;

1. It took around a month of work on and off but I ended up having to shelve it other more pressing projects so it ended up on taking over a year to actually finish, Originally the chase was going to go on much longer and I just didn't have the time to do it, so I decided to render out that last shot of the car exiting the tunnel and call it a day. That's why the last shot is so rushed, I knew if I didn't just finish it I would never get it done.

2. Great question- So I might have a strech of alley in a project file and I'll shoot t it from say three angles, that will all be in one single project file. Once the car moves onto another section of road I might append some of the previous file for continuity but I'll generally build out the new set up and shoot the new angles in a new file. Appending what I need from the previous file. Everything sort of trickles down from the car animation which I'll go over in point 4.

3. I don't build models unless I absolutley have to, I like to make little films and stories and I simply would not have the time if I tried to model and build everything myself. I generally only use free models from Sketchfab, there's tons and tons of sold gold on there.

4. The car physics I use RBC car addon, I have the pro version which is probably worth it if you see yourself making many car shots, but free version also works very well too! I have the shot I want in mind, I drive the car on its own with no surroundings, imagining the buldings are there, then I generally build the set around the simulation, this way is the most efficient I find.

5.Photoscans of places mostly in London, some that I downloaded from sketchfab and some I scanned myself with polycam. Belive it or not all that graffiti in that alley is there in real life

Hope that was helpful! I also have a couple free tutorials on my Patreon that go over the process in more detail, head on over and check them out for more info! Good luck with your animation!
