Re: Einstein would say this is insane...
And...

...the problem seems linked to Sketchup-created objects.

I created a comparable scene using only standard SH3D furniture items and repeatedly rendered it; the renders are all identical.

I should note the glasses from my first test are only a single Sketchup surface thick; that is, the outside of the glass is one Sketchup face, with the inside of the glass being the opposite face. (The base of the glass, which is the only other area to render differently in subsequent renders, is also similarly single-surfaced; with the top of the base aligned the same way as the outside of the glass.) Even though both faces of the glass were mapped with the same texture, something about the way Sketchup models the object causes problems with SunFlow.

I'm still uncertain why subsequent renders would generate different images or which variable(s) is being set to a different value in each render, but at least we know this isn't a general concern. However, it suggests some Sketchup models may not easily be made SH3D-safe....
