Assuming this was due to some other bug, closing it! Let me know if it pops up again :)

This should work as of 1.14, let me know if it doesn't!

Closing due to age and not having seen the issue since

This has now been fixed in 1.16

The rotate issue has now been fixed as of 1.16, and the panning issue is not a bug. That's simply because the sprite is panned away, never to be seen again :)

In addition, now that 1.15 is out, you can tag it as a normal, which will make the inspector warn the user is the selected texture isn't a normal map :)

This is now implemented in 1.15 :)

I think, though I'm not sure, they are using the same shader. Try the stuff I wrote above :)

Maybe, that's a multi-pass effect that may be too tricky/time-consuming to set up at the moment

Not sure if it is I'm afraid :(
