MX Simulator

Hello,
I've been following aeffertz's tutorial on satelite track making religiously, and have run into a problem that seems relatively small, but is completely throwing things off. I have finished part 3/4 of aeffertz's tutorials (not watching part 4 because I'm going to cover the whole track in decals anyways) and have everything in place (I think). So, I boot up the game in editor mode, and go to my track file. As it's loading, it stops, showing this:
I had left the lighting, shading, etc. stock so I could mess with it later. After playing around with the shading.ppm for a bit, I found that putting the dimensions to 2049x2049 allows the track to boot up, but it looks like this:
I truly do not know what to do at this point. I will include pics of all my decals and track overlay and stuff if it will make a difference.
Decals file:
Track overlay in decal folder:
Terrain:
Terrain.hf:
Thank you to anyone who takes the time to respond.

Right now, your terrain.hf file starts with 10, meaning your track is 2049x2049.

However, the shading files you have are 1025x1025. You can simply open the shading files and resize them to 2049x2049 in whatever photo editor you are using and save them. Should work!

Or just download these two and replace the ones you have in your track folder.

Thank you so far, but the track still looks like this:

Did I insert the track overlay into the decals file the wrong way?

You can't have spaces in the folder name, that's why.

Thank you guys so much, would have never figured it out myself.
