All kinds of crashes...

After upgrading to version 4 I've been getting so many crashes that I can't keep track of them all. I get crashes when adding a VRayOrnatrixMod. I get a crash when adding mesh strips to Ox Hair from Mesh Strips. I get a crash when adding an OxStrandCurling on top of OxStrandLength, and when changing the View Hairs % in Ox Hair from Mesh Strips, and when starting a render, and when the render completes... etc

The problem is that none of these are consistent, so there is nothing solid that I can report. But I figured that I should let you know anyway.

Maybe I'm doing something wrong, though. I've got 5 Hair Strips objects in my scene. Is that too many? Is there a max number of hairs that can be rendered before the scene becomes unstable? I have 64 GB of RAM on my machine and I constantly monitor it, but it's not maxing out. Could there be some kind of viewport issue?

I'm at a loss here, but I'm hoping that future updates will solve these crashes. Is anyone else having this much trouble?

My system:

- i7 5960x overclocked to 4.4GHz

- Asus Rampage V Extreme 

- 64 GB RAM

- 2 x GTX 980 Tis

- 4 TB SSDs

- EVGA 1300 watt PSU

- Corsair water cooling

- Whipped cream and a cherry on top (and some cat hair)

Thank you for the report, it seems to be all revolving around hair from mesh strips object so that is where the instability is probably coming from. I will need to mess around with it more.

There are no limits in terms of strip or hair count and 64GB ram is plenty enough to handle even the toughest scenarios. It could be an update issue. Do you have animation with the strips?

Thanks, Marsel. No animation. It's just a still image.

I found that once I stopped tinkering with the settings there were no more crashes and I can now render without worries. But as soon as I go back to adjust any of the Ox modifiers I start to get random crashes. I don't know if that is useful for you to know, but I've applied NURMS smoothing to all the mesh strips.

It's good to know you're on it because it's such a great feature!

 

Cheers!

I've been messing around with hair from mesh strips for the past half hour or so, trying all kinds of modifiers on it and changing different values but I couldn't get anything to be unstable, seems to work 100% here. It would be great if there was a reproducible scenario or a scene I can try.

Yes it would. I will pay closer attention to see if I can spot any specific patterns and then let you know. Thanks for looking into this, Marsel!
