geometry motion blur causes crash

[Jpjapers]

Hi, ive been trying to enable geometry motion blur and each time i press render it crashes out with a bug report error. The scene is also using volumetric lighting and a zdepth pass which could maybe be causing a conflict somewhere? But either way at the moment i cant seem to get it to work. is it a known buggy setting?

Thanks
Jack

Can you upload the scene? http://corona-renderer.com/upload

[Jpjapers]

full archive with all textures?

[Ondra]

best option is a simplified scene where the bug still happens
next best one is full archive
worst is just .max without testing if the bug will demonstrate without textures/xrefs/proxies/...

ok ill strip it down and see if it still happens then upload it in a little while.

hi,
is there a progress? Do you have the scene and/or minidump?

I am experiencing a "Crash" using Corona 1.3 and MotionBlur right now.

    I have a scene with a lot of objects coming from 0% scale to 100% in 1 or 2 frames (Poping on scene). And when i turn on interactive render and motionblur it renders ok, when use Interactive Render it goes ok, while scrubbing timeline it refreshes the render...
    But when i do Production render with a range, it just renders the first frame, and get the smile face turning on a infinite loop on the second frame, it never finishes it... I am setting the rendertime to 5 min/frame... (Is this a problem) ? It´s just a prevew render...
    When i turn MotionBlur off it renders ok.

I think the problem may be your objects set to 0% scale. Can you check if the same happens if you set the scale to 1%? Or just if you scale an object from 50 to 100%?

   I didn´t found a solution for my problem, but it´s not (for sure) only a problem with Corona. I´ve discovered that a single object crashes all the time when i turn motionblur on. ONly one object among 3600 objects that are scaling from 0 to 100% and working... It´s a very weird problem... I will upload the object to Corona team to get some better feedback...
    At the end, i´ve discovered that some other objects are making corona to goes on loop... It just crash or get stuck at the end of GI/cache build... So strange...

Ok, we need the faulty objects, scenes, and possibly minidumps from the crashes/freezes/loops: https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006
