I don't know how to make a texture file and I need to be shown how to do something instead of just being told. Maybe being autistic has to do with it.
Jordon,
It's not as difficult as you think:
Download Gimp (free), use MS Paint (free), purchase PaintShop Pro (inexpensive), or spend a lot of money on Photoshop.
Create a 64 x 64 square of black color.
Save the file as engine_black.tga
Uncheck the option for file compression
In Content Manager, open the asset for editing in Explorer.
Paste your file in there.
Ensure that there is an engine_black.texture.txt file there. Hint: Copy another texture.txt file and edit its contents and save it as engine_black.texture.txt
Check the asset again for errors in Content Manager. The program will tell you if something is wrong or missing.
If all is okay, close your asset's folder.
Commit the asset in Content Manager, and you're ready to go.
It's more difficult to type this than it is to actually do.
