Hi guys, I have this image here with two renders, both with the same Kray settings (everything option 'Low' with sampling option 'Medium'). In the top image all surfaces are set-up with nodes, in the lower image all surfaces are set-up with the standard LW material (except the whiskey glass and the ...

Ok, one more question, not to be snugg but just curious, if you shouldn't use a high recursion level, why can you add a footer cmd with level 100 ? In what cases would you use that?

cheers, Simon

i Jure, Thanks for your reply. I know recursion in Lightwave means how many times a ray reflects or refracts, but my perception is that Kray uses the recursion level as the number of times a ray bounces inside the scene. I got that idea from the wiki. It also states that a high recursion number does...

This is after I switched off all nodes in the surface editor.
After adding the 'recursive 100' command, LW freezes.
It also freezes if I increase the recursive level through the Render Global tab in LW instead of the Footer cmd.

Since Kray for Mac is unstable I've switched to Windows for rendering my scene. I've loaded up my room with shaders, most of them nodal. I load up my scene, set my resolution multiplier to 25%, select Kray Options, switch to Photon Estimate Precomputed and hit Render Frame. No problem there, Kray re...

Hi guys,

After more playing with some of the settings I got this result and I'm fairly happy with it.
Render time about 45 min at 1920 * 1080 on 8 cores.
Thank you both for helping me, without it I would never have gotten this far!

Cheers,

Simon

Hi Jure and Januzsz, Thank you both for helping me on this project. I did the photon-tab tutorial (the videos) and it is very enlightening, exactly what a tutorial should be. Here is a picture from my photon-tab, with the result. It looks much much better than before, but still it has some problems....

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

Hi guys, I'm trying my hand at this interior but I have a hard time to get some good results. I get all these strange light-leaks everywhere, even though the meshes are watertight. When I switch on path-tracing in the FG tab the light-leaks are gone but also my contact shadows on the stuff on the ta...

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 Jure,

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

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 phen...

Hi Jure,

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

Cheers, Simon

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 befo...

That wouldn't necessarily work, though. The GI would still be affected by the "hidden" geometry. Ah yes, you might be right there, propably need a seperate buffer for the radiosity for every object also then. Now if we throw the whole buffer thing around... If buffers were asigned to obje...
