I've checked and it wasn't fixed in 1.3.17.

As our experience showed that Global Illumination (the
shader uses a single indirectdiffuse()) is unstable
depending not on model complexity, but on the resolution
of the image!

You can render a scene in lo-res, but Pixie will crash
rendering the same in higher-res. And you can render the
scene without indirectdiffuse() even in higher-res.
It's very deterministic: it always crashes at the same
"bucket".

(My first thought would be some kind of a memory
problem, because in our app it crashes in the C++ runtime
lib.)

Hi Aron,

Sorry about the late response. My SF forum monitor got
screwed up.

If you send me an example scene that demonstrates the
problem, I can fix it.

Thanks

Okan

Hi Okan!

Thanks a lot for the fix in advance.
If you grab http://d-eyes.pganet.com/~aron/
PixieGIHiresCrash.zip, you'll find:
- a dummy shader which uses indirectdiffuse
- a RIB with 3 "Format" resolution settings
- the first two resolution can be rendered, the third
(HIRES) will crash at the same bucket every time
I hope it helps.
