Is it possible to build a custom Park Entrance, or move the existing one to a different location?

Not sure what game you are talking about, but for RCT3 you can use DasMatze's Invisible park entrances, then create your own building/style. RCT2 has a similar thing, but I can't think of the name of it.

This my park entrance http://forums.rctgo.com/thread-20628.html

I'm working in Roller Coaster Tycoon 3 with the "Soaked" expansion pack. Where do I get this "invisible park entrances" download?

Here is a YouTube video from one of our members who shows where and how to download it.

Can anyone help me with custom scenery?
I have gadgets coaster goodies up and working but when I put jCats steelworx in it just makes all custom scenery not work. It happens with other CS's not just steelworx. Please help!

Have you gotten the situation fixed? If not, I would try re-installing both custom scenery sets.
Make sure you are downloading the steelworks from:

When you extract the steelworks file there is the main folder and another folder within it. Take that folder and put it in Style/Themed. Here is the example:

I hope it helps.
