Hi all,

I have an interior scene in LW 10.0 on the mac. The scene is 1.6 mil polies big. When I render with the native LW renderer, there is no problem (other that speed of course), but when I render with Kray 2.2 it crashes a lot of times. In general, I can do two or three test renders in Kray before LW crashes to desktop. It is a clay render so no fancy shaders, and only one spotlight is used.

I haven't found a pattern yet in the crashes but it seems that when I increase the settings of Photons and/or FG, I also increase the chance of a crash.

I just tested an empty scene, and it still crashes after a couple of renders.

These are my specs:
Mac Pro, 2 x 2.8 Ghz quad-core Xeon
10 Gb 800 MHz
NVIDIA GeForce 8800 GT
Mac OSX 10.6.5
LW 10.0 rev 2065
Kray 2.2 rev 1211

I think something may be wrong with your config files or Kray installation. Please try clearing configs and reinstalling Kray. If it doesn't help please send us the scene so we can test it.

Hi Jure,

I will do that. I'll keep you informed.
Thanks mate.

Cheers, Simon

Hi Jure,

I've removed LW and Kray, re-downloaded and installed both again.
It is a bit more stable than before but I still get crashes to desktop.
A strange thing I noticed is that Kray keeps spawning new render windows.
Twice I got a CTD when I tried to close these.
Here is a screenshot of the phenomena.

Cheers, Simon

ps: LW is now the latest version, rev 2067.

Could you please send us the scene together with crash logs or video showing the crash, so we can try and replicate the problem here?

Hi Jure,

I've send you a PM with the download adress.

Cheers, Simon

this is a known problem and the developer is informed about it. the only way to avoid it is to close the render window manually before any new rendering - no more than 1 render window at any time should be open. also beware of accidentally rendering in 2 windows, this can happen if clicking twice in a fast sequence onto the render button.

cheers

Ah, I didn't know. Though I seem to remember (not sure) that it sometimes also crashed when I closed the only one render window.
Thanks for letting me know!

Cheers, Simon

hi . why u can used lightwave 9.6 its perfect with kray no bug at all.


me 2 i found buy in lightwaveIO and kray 2.2 no as you case but when i do test render and i do other render sometimes my render will be all black its bug kray 2.2 and lightwaveIO . and this bug i hve see it in the same version of lightwave 9.6 and kray 2.1 its the same problem.

try lightwave3d 9.6 no crash build ..... i miss exactly number and kray 2.2 .


or mybe . i have seen this problem when i used kray b1.7 and when i used (delectric node) o,n it .dont used delictric i think .

Thanks for your sugestion, lightwave3d, that would be a good option.

Personally, I've switched to the windows version of LW and Kray and this combination works perfectly.

Thanks for thinking along though!

Cheers,

Simon

I would like to ask everyone again to send us any bugs they may encounter. It's the only way we can make the software better and more stable.
