Arnold has some interesting terminology...not sure if its foul language but I kicked an ass file. However, it does not crash but it doesn’t render the highlights either.
Similar happened from within XSI and the render region...sometimes it will render when scrubbing in the timeline back to the original frame. Even when it renders, it doesn’t render the hilights. With kick, it renders straight away but no hilights are rendered when MB is turned on. Both XSI and kick give these error: ' ERROR : [arnold] [polymesh] : different number of motion keys in vertex/normal arrays: #normal keys: 1, #vertex keys: 2 ' ERROR : [arnold] [polymesh] : different number of motion keys in vertex/normal arrays: #normal keys: 1, #vertex keys: 2 ' ERROR : [arnold] [polymesh] : different number of motion keys in vertex/normal arrays: #normal keys: 1, #vertex keys: 2 What seemes like an issue with scene geometry isn’t actually related to a polymesh in the scene. It happens even if all geometry is deleted. Three errors with three lights in the scene.... I suspect it to be the arnold area lights itself. Maybe when arnold is building a geometry for the visible area lights to render them. I might dig into that further and post it on the more appropriate channels regarding arnold. But so far it seems like an arnold issue.

I will try an ass export.

If you could export an ass file and kick it, then it could be an Arnold bug. Except if there are a bunch of SItoA shaders in the scene...

Well, in that particular scene arnold crashes when using motion blur. I nailed it down to settings in the light shader (arnold quad light). The values in the light shader for camera visibilty as well as transmission visibility are both zero by default. Maybe for a reason. Then it renders but changing them to any other value will crash arnold when using motion blur. Unfortunatly you would need transmission visibility for correct reflections in the glass. Not sure if its an arnold or SItoA bug. I’m using SItoA 7.2.2.0. I worked around it using grids for the transmissive highlights and switched off anything but the specular transmission for the grids. A bit awkward... that’s what I would expect from mental ray, not arnold. :( Does anyone know if it’s a known bug, limitation or maybe something else?
