Iray NOT crashing...I don't know why.

Scavenger

So, I've found Iray VERY VERY crashy. I can do around 4-7 renders with iray...of any size or durration...full render or spot.  Then if, my entire computer hasn't frozen during any of that, and I quit Daz, I'll see some graphic distoration bands on the screen, and I'll crash the computer if I re-open Daz, it'll freeze the computer.  A restart along the way re-set all of this.  I've been planning on documenting it for more serious trouble shooting at some point.

BUT....

For the past 24 hours...no crash.. a whole bunch of renders full and partial, including two multiple hour renders,  adjusting poses, lights, shaders, maps...no crashes, no distortion..a quit and reopen with no problem...and I don't know why.

Below are the render settings between what I was using in the final big render today and the default (or at least what was there after I closed and restarted Daz with a blank canvas), which is the only thing I can think of as changing things...but I tried multiple settings, multiple light configurations....different pre-sets. and things... thoughout .  I don't think it was the objects in the picture..a figure, chair, and a primative set as a shadow catcher, BECAUSE I crashed before the non-crashing period with literaly just a cylinder and plane to TEST the shadow catcher thing.

I had unistalled the default lights and scripts and reinstalled them earlier (again for testing the shadow catcher instructions) but the cylinder/plane crash was after that, so I don't think that was it...

Other computer stuff going on wasn't any different than normal.

The one time I checked my processor usage, Daz was in the 600% range..normally it's in the 700% range.  (Macs show a 100% per processor, because Steve Jobs never felt that was worth modernizing when mulit-processors became a thing..or something)...

One change I made at some point was changing Optimization from Memory to Speed..but I'm pretty sure I usually have it on that, and I know I've played with that in the past to see if there's any difference.

 

SO TO WRAP UP...Iray NOT Crashing my computer every 10-15 minutes is very weird, and I'd love to know what changed to make it this way.

Iray dose not work well with AMD graphic cards, only the new Matrix card is compatable.

Richard Haseltine

Iray will not use AMD cards, but it will work quite happily as a CPU renderer on AMD systems.

Why are y'all talking about AMD cards? That has nothing to do with this topic.

actually I like that mac shows the CPU thread. which is actually quite useful since multithread CPU's can be doing multiple work and various "heavy lifting" so If LuxRender is eating 1600% of my cpu I know 16 threads across two core 4 Xeon CPU's are running at capacity. If I cut to 8 threads it drops to ~800%. If you're unfamiliar with your CPU it can be a bit confusing at least on the mac forums it does come up from time to time.

if you go back to crashing you may want to look into the Mac Cuda drivers from Nvidia which are designed outside of Apples influence which is a very good thing seeing how Apple clustered fubar-ed the OpenCL drivers in Yosemite.

Oh, I'm just commenting that they use 800% for the cores, rather than ..I don't know 8 seperate 100%'s? I guess I see the problem there.

I haven't done any serious rendering since the not crash time..so I don't know what condition things are in right now, and still have no idea why it suddenly went from crash to non crash.

 

(I have the latest cuda drivers...and I'm still in Mavericks because Yosemite looks ugly)
