I discovered way to make any actor in cortex command invisible when i was making a railgun.
I wont know how it works but it works only if you look to right.
When looking left the device turns to a striped square(i dont know why)

And im not able to make it better because i dont know how it works.

(pics coming later)

The sprite isn't in palette.

It's not a feature, it's a bug.

And one that you're lucky didn't crash your game.

An invisible upaletted sprite masking other stuff is still neat though.
And who say's a bug can't be used as a feature? This is mod making, not releases.

I can think of some ways it could be improved upon, but none of them are really even worth bothering with if it can't work leftward as well. But maybe in an application in which horizontal flipping never occurs this could be useful. Oh great, now I have yet another idea delaying my faction.
