Hey Jens,
I needed to clean up the scene a bit: www.imagefront.de/tmp/2307_imagefront_benchmark_arnold.zip <http://www.imagefront.de/tmp/2307_imagefront_benchmark_arnold.zip> It’s the XSI project folder with relative file pathes so it should work straight away. The scene has a readme annotation which explains it a bit. Basically just draw a region (pass settings are used), arnold will render the hilights. Then turn on MB... It also contains the photoshop file I used for direct comparison. BTW the bug is with CPU and GPU rendering in Arnold.

It sounds like an Arnold issue and not an SItoA issue but I would love to take a look at that scene and see what's going on. So please send it if you can. If it's an Arnold issue, it's even more important to get it fixed :) //Jens On Thu, Aug 10, 2023 at 8:47 PM Sven Constable <[email protected] <mailto:[email protected]> > wrote: Hi, anybody still here? :) Recently I was working on an old test scene again to compare arnold and redshift (and even mr for a good amount of fun). 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? You can see the issue here (the glass model has a 360 rotation over 50 frames) www.imagefront.de/tmp/testscene_armadillo_comparison.jpg <http://www.imagefront.de/tmp/testscene_armadillo_comparison.jpg> Sven -- You received this message because you are subscribed to the Google Groups "Softimage Mailing List" group.
