Ha ha! I found the TexMod program and have put it to use. Included in the download are 2 .tpf files; Extras.tpf and Ground.tpf. These are files used by the "TexMod" program and injects the textures directly into the game without changing any game files.
Ground.tpf contains realistic replacements of all in game terrains and cliffs. They are x2 the resolution of the org game textures and at 512x res. Future releases will contain different resolutions.
Extras.tpf contains several select textures. 1024x star map, slightly detailed clouds, modified sky color map, removed galaxy "band" texture, and modified light glow/ halo texture.
These files can be used together or by themselves. I take no responsibility if you mess anything up. Use at your own risk, but everything on my end has worked just fine. Created by Old-Spice.

This program allows set to easily switch around their shared texture files allowing a set to have varying textures depending on the project you are working on.
Important: The textures have to be provided by the author of the CS-set and can only be used if the author prepared the set accordingly.
Are you a cs-creator and want to use it for your set? There is a full description included in the download. Created by Dutcher.

Make your own Animated Flag for RCT3 Tool Set For Photoshop.
A full tutorial on how to use the files in this kit can be found in the "Make Your Own Animated Flag" Tool Set thread on SGW.
Essential Requirements
Adobe Photoshop (PS) CS5 or later (trial or otherwise). I'm unsure whether the *.atn file will work in earlier versions of Photoshop, you can but try. Sometimes I have success with older/newer CS versions with newer/older droplets and/or actions I've made or downloaded. It seems a bit hit and miss.
RCT3Importer v18b1. RCT3Importer v18b2 gives an error when re-loading the *.ase file from its previously saved *.xml file with an animated texture listed within it (See Importer flags errors when opening animated texture *.xml file for more details). So if you think you may need to ever edit the animations etc., use the v18b1 which can be downloaded from SourceForge.net

Pavement Essentials Templates v7 by Aceana
A set of templates for Aceana's Pavement Essentials set, includes ASE files, SID files and sample textures. Created by Aceana.

I am swamped with structures that have remained unfinished that I plan to complete by the end of this year. Unfortunately, there are a select few that I am choosing to let go since I have no idea what to do with them. Maybe you guys would be able to find use for them, be able to build on them, or incorporate some aspect of them for a current structure you are developing!
So, feel free to use these in your parks or projects, and be sure to give proper credit when it is due!
Included: modern-style diner, adventure windmill, and a kooky rustic shack!
Note: I only have the AdventureMill photo available, as I am too lazy to reinstall the cs for the others to take pics. Created by PandaCoasters.

This set is based on the same effects made by pyrotechnic company Le Maitre Ltd. The effects are owned by them, I have just replicated some of them for use in the game. This set is V1. V2 may follow soon.
