Oh thanks for the reply! I think I managed to pass the variables but no success yet... Should I also update the camera shader or they are just for lights? Because there're no light sources in my project yet, since I'm going for a very retro vibe, and I saw that your camera is totally different from the g3d, idk if that may be the difference, since I'm using the default g3d one.
Gonna try some more times here, but thanks again, this has been pretty tough
[EDIT] nvm, managed to get it working!
