The Breakable Metal acts as a half-mirror, Catelite made a full list of what Photons can now do. My Powder is still not working, nor the test My friend made a SSE4 version of Powder Toy v43 Beta actually, anyone who wants it, speak to me.
cracker64 AWESOME mod. I think it might just replace my main version of Powder Toy.
(P.S. With the working switch, i was able to make a fully functional safe with number pad, with a code that you have to enter in order.(And it doesn't even take up half the screen!)
