The listing of the City Escape Lego Ideas page got taken down due to licensing conflicts (which I think is a ridiculous new rule but I won't spend more time griping about it), but the light at the end of this tunnel is that getting the set to be compatible with preexisting parts was easier done than said. I'll be including the part list file for BrickLink and the original Lego Digital Designer file for rendering. Unfortunately, it costs a pretty penny to buy all the parts- but, at the very least, the goal of it becoming a real, "tangible" thing is now technically possible.
I'm also including folders containing all of the custom decals I created for this project, so that those who use LDD to POV-Ray can apply them as they'd like (except the decal on the side of the truck- that one I had to apply manually).
I'll be keeping this post permanently patron only, primarily so if I choose to put all of these files together and sell them I can. Thank you to everyone who helped support this set while it was on Ideas (even if its time was short), and I've got more things coming in the near future.
