^Thanks! I'll try to answer all your questions.
The keep out doors were made by Imagineer John for Fishermans Ghost Mine ride, and can be downloaded at the Ghost Mine website here: While you are there I highly recommend you check out his ride, it is fantastic. The hanging body in The Tomb was given to me by a CS maker (PB&J) after he saw me asking about it in a thread. He happened to like my work so he gave it to me. He has only given it to 3 people (that I know of) and many many people have asked.
The sound effects in my video are all found via google search, which takes a very very long time. I get much of my music from freeplaymusic.com.
For recording, using an external recorder is a ver bad choice as rct3's frame rate is horrible. Instead, use ctrl + shift + f11. Your game will be virtually unplayable until you stop recording with ctrl+shift+f11. It can take awhile to record depending on your computer but if you go into your my videos/rct3 folder after you will find a high quality video of what you recorded. For the fcre (Flying Camera Route Editor) you don't have to use D Lean, just press ctrl + shift + 0. You can find a good tutorial for this
Hope I was helpful, and thanks for the sub!
