--- Comment #19 from Grigori Goronzy greg@chown.ath.cx --- By the way, I really wonder how this manages to work correctly with the blobs. Are they fixing up the shader on demand somehow?
Trine 2 (the Steam version) was updated a while ago, but sadly they haven't fixed this, despite promising to do so. :(
