Crashing in 1.5!

[v-cube]

One more question: what is your graphics card and drivers?

Best regards,
Vlado

The graphic card is a Geforce 6800 (I think a version with only 128 MB RAM). Drivers are (referring to the windows hardware properties tab) version number 8.4.2.1, Date 09.03.2006.

Do you think a driver update might help?

I'm using viz07, and I found that if I use PPT (just for previewing/testing) I can only render once. If I cancel the render and then start again, it crashes viz. Doesn't happen with QMC/LC.

Although without the use of the physical camera the crashes are not occurring every time, I still experience regular crashes which seem to accumulate when I switch from the 3D Studio window to another application window (e.g. Firefox). Another crash trigger is vray fur, which seems to be nearly as bad as the physical camera on my System -> crashes approximately at 50% of all render attempts…

Happy bug hunting

All this seems to me somehow viewport- related to me (particularly the switching from and to 3dsmax/VIZ). Did you have a previous build of V-Ray on that machine? If yes, did it work?

Also another question: what is your viewport driver? Does switching the driver help for these issues?

I sometimes work from other machines so I have vrlserver to auth the license. Should I try running it without vrlserver running? Although like I said I've had no problems with 1.47 for ages now.

For video: I'm running a quadro 1400 with the maxtreme 8 drivers and 84.26 video drivers.

I've emailed you the acminidump.dmp files (hope these are the right ones as they don't start with "3dsmax").

Also, I've been running it a bit more this morning and had no problems, tried using vraysun, sky, cameras, with no problems until I tried rendering to the VFB with these components. I Alt-Tab'd to another window (vray forums ) and Viz closed on me. This generated the minidump file I'm sending you. Maybe it's just a coincidence with the VFB though.

Thanks,

Same here. See post above.

EDIT: I've confirmed that this is definitely a problem on my machine. Specifically, switching between the VFB and another window (IE6, Outlook, etc). If I use the standard max render window I can switch back and forth without any lockups.

EDIT #2: It's getting a little weirder: this really only happens on one scene that I have. I can render another scene fine thru VFB and switch between it and other programs. The scene that does crash using the VFB will also crash if I render to the VFB before I render to the normal render window. It crashes during the "Updating Objects" phase of the render. If I render to the normal window and then the the VFB it will render fine as long as I don't switch programs. VLADO: I can try emailing the scene to you but it may be quite large due to the proxies (trees).

Also, I should mention that the scene in question is a linked DWG (as is the one that works). I don't think it matters but perhaps it's related.

well before the installation of 1.5 today (downloaded at appr. 10 am) I had no problems, although I remember a few occasions were manipulating the curves while rendering in the VFB lead to a crash, but it was very seldom...

One more twist to this... The scene that used to render fine to the VFB no longer does (i.e if I switch to another window it closes VIZ). The scene is the scene was the same as before except I added a Physical Camera, VRay Sun and Sky. If I remove these pieces it renders fine to the VRAY VFB with no crashes although I'm not sure which component is killing it.

[dlparisi]

Arrggghhh!! Scratch that last entry. I can flip between Viz and other programs but if I cancel the render it will still crash.

[vlado]

Thanks for the input; I think I'm beginning to understand what is going on...

I seem to be getting crashes in viz2006 w/ 1.5 when I try to render a "blowup."
Seems to happen when it starts to load bitmaps(?) but it will render fine when rendering "view."

If you are using the light cache, try turning off the "show calc phase" option and see if this helps.
