In-game distortion in wall coloring

You are meant to use the version of blender that the path is s4s settings leads to. S4S will output the file to suit that version specifically. 
whether you can switch between them depends on the versions.
for example, you can jump between 2.7x versions and save the blend in any of them (so long they have the plugin).
you cannot jump between 2.7x and 3.3 versions, cannot open a blend made for 3.3 in 2.7x, cannot append, they are like two completely different programs by now.
You can open a blend made for 2.7x in 3.3 but a re-saved version of it won’t import into s4s.

if that was not what you meant, what versions do you have?


I tried to transfer it to version 3.3 in 2.70. It seemed empty from him. Thank you for your answers. Sorry if I've kept you busy, but I'm trying to learn as much as I can.
