Projection parameters are not for any projection they're specifically for the parameters of the projection of the camera. As for decal projection shaders - I'm not sure how you do that to be honest, so I'm not sure if it's possible in SF!

Under the blending settings, uncheck the box that says "Per-object refraction/scene color". Uncheck that and give your texture a name :)

I'll look into this for the next version

Nope. Any errors in the log?

It should be, yeah

I'll look into this

This has to do with math :)
Time is an ever increasing value. You can't control speed by multiplying an ever increasing Time value. You'd be better off simply controlling the panning amount directly rather than multiplying the speed

Odd! Glad it worked out anyhow :)

No idea really, the camera position in SF isn't even saved in the files. It should reset on every load :(
I really have no idea.
Perhaps you can try going through this procedure:
