any way to force vray to stop rendering if cancel doesn't work?

[stayinwonderland]

vray has started doing this thing where, if 3ds max is auto-saving mid-render (might be specifically during light cache calcs) the calculations just go on indefinitely and if you try to cancel it does nothing so I have to force quit.

 

Is there a way to fully shut down vray to get out of this?

not really, when VRay start LC calculation, it is hard to stop it.

You should change the auto backup time. I would recommend to setup save incremental in your 3D Max and get used to save constantly instead of relying on auto back ups.

thanks, I've never tried the incremental thing. I'll give it a go and keep saving before the render. I wish, like in photoshop, saving could be in the background and not slow things down.

well yes that would ne nice, but so far the only thing we get is the possibility to cancel the autosave.

tho I don't remember ever run into the problem of autosave when rendering...

That's definitely not an expected behavior though, so you might write to ChaosGroup folks to solve this.

 

Autosave during render is inconvenient and does halt/freeze everything briefly during render but doesn't jeopardize it any further.

Hi, I'm currently having the same problem.

Don't know if this was solved in newer versions(I'm still using Max 2014 and Vray 2.40:D ), however everytime Max starts Autosaving when Light Cache is calculating(happens quite often actually), it goes forever and there is nothing I can do to stop it, except to kill Max entirely.

Unfortunately, hitting ESC to (supposedly)stop the Autosave doesn't help because it in fact tries to stop the LC calculation instead (VRay status window displays "Cancelled"), but off course, LC still goes on forever. Hitting "Cancel" in Render progress window does nothing.

 

Disabling the Autosave looks like the only way to solve this, which is unfortunate, because if Max crashes for any other reason, Autoback is usually the last resort. Since the scene file already has around 1GB, manual incremental saves would be, well, cumbersome to handle to say at least.

Also, until now I used several previous Max versions and never had any problems with Autoback. In fact, I'm pretty sure those older versions had Autosave running in the background because I never even noticed that something was saved. Another strange thing is that I didn't change anything with my Max or Vray for at least a year(i.e. didn't installed any upgrades, service packs etc.), finished several projects earlier and never encountered such problem.

yeah, same here but with 2012. Although I'm trying to think if this happened after the 2.4 thing. Hmmm.
