Mmmh the log is empty, strange.
I've checked the examples of Simon and either I don't understand, either it's as usual like I did before.
Here 2 screenshots of my shaders settings:
The main script (latest version)
And the shaders that I try to activate
And in the game nothing changes, there are no shader effects whatever the values I try in the shaders.
Usually it used to work fine, I have been using the shaders for a while (since Catyph) and experimented many different things.
I must be missing something....
I'll probably need to read furthermore the new examples and changes explained by Simon, but even though if the old version doesn't work anymore it should be said in the log, no?
