::::PS: Reflection means to me a mirrored image. I call ''our'' reflection a fake since it doesn't reflect (mirror) the environment but shows another image. Look at the fury's head closely: there's just the bomb_fire texture inside. --[[User:Paradox-01|Paradox-01]] 17:59, 13 October 2008 (CEST) | ::::PS: Reflection means to me a mirrored image.

:::::If you consider non-convex objects (like two mirrors "seeing" each other), you can see that "real" reflections of the environment would be very heavy to compute (the multiple reflections can require a virtual infinity of rendering passes), so naturally games use more or less elaborate "fakes". Oni's fake is actually quite primitive and a reflective ball, for example, won't look realistic at all as you move around it (I hate that ^_^). But I digress; I was just confused by the word "inside" as you used it. Now... back to cases 1-3: cases 1 and 3 indeed "don't seem to work"; for 3, the engine ignores animations when setting up the envmap; for 1, it's a shame, but the engine ignores animations when setting up the windows, too; 2 ''does'' work, but since OniSplit doesn't allow you to create the right thing directly right now, both of us had to use a workaround and I have no idea where you messed up. Try again ^_^ --[[User:Geyser|geyser]] 02:33, 14 October 2008 (CEST) | :::::If you consider non-convex objects (like two mirrors "seeing" each other), you can see that "real" reflections of the environment would be very heavy to compute (the multiple reflections can require a virtual infinity of rendering passes), so naturally games use more or less elaborate "fakes".
