Crash when setting triplanar level to "3 Normal" for standard or horizon terrain

OS: Windows 11 23H2
Version: Stunt Rally 3.1

When setting the triplanar level to "3 Normal" for standard or horizon terrain in the settings menus, the game crashes with a shader compilation error the next time it tries to load a track (e.g. press F5 after changing the setting).

It's one of those options marked as "= todo, not done" or buggy.
Didn't expect crash though. Could you attach ogre.log?
But yeah anyway, triplanar normal has a bug, reported on Ogre forum, not fixed, IDK how.

In case of shader errors:
The next step (very optional) would be enabling in game.cfg

debug_properties = on
debug_shaders = on

Finding out the last line in ogre.log saying which shader failed and attaching that file too.

I have hidden this option from Gui for now. There is a lot of issues on forum to deal with first. So I leave this is for later.
