    Is it me, or is box projection broken for cubemaps? It seems that the box it projects to is usually larger than what I'm setting it to project to.

    Maybe it's mac specific since I'm working on a Mac atm...?

    Edit: Gah, forgot to add a prefix, I guess it should be in Graphics.

    It has something to do with the new deferred per pixel code. Switching to Forward (and losing per pixel) makes the projection correct.

    Yeah the boxes are essentially enlarged by the "blend distance" of the probe. Otherwise the box projection breaks down and, well, stops working.

    That.... Makes sense. But how is that ok? Doesn't it make the box projections much less useful now, since even in a rectangular room the reflections are still going to be "wrong".

    (Was the change made with the, now delayed, ssrr in mind, that I guess will compensate?)

    EDIT: Nevermind, just noticed, you can put blend distance to 0 and then the projection is "correct", so everything is good!
