Looking good, great job with the trees.

Great news, Thank you.

I want to thank Grzegorz for looking into the render problem, so far everything seem to be working fine.

Thanks Janusz

Hi Everyone, It looks like 2 separate problems here. One slow down related to instances and another slow down when rendering same scene more than once. Simple scenes (the simpler the better) that ilustrates both issues are needed. I've got examples of instancing problem, but more examples like that...

I make some minor random change in a surface, or add an object and again problem.
I make a new scene and I am adding the objects one by on with a plane diffuse surface and problem again.
I cannot work with Kray anymore.

Have been doing tests and strange things are happening.
I deleted about 10 objects and the scene was rendering fine.
So I loaded again the original scene with the 10 objects that I have deleted and is rendering also fine (at least for now).
It seems quite random.

No instances here and i have 100 or more times slower.
Can I send somewhere a problematic scene?

Rolled back to 2.55 same problem. I noticed that even when a scene renders fine still this problem appear if I make i.e a surface change. After that even if I undo the change the problem persists. Also if I don't restart LW and load a different scene I have the same problem. I even test it in anothe...

During the second in a row render the program is on the verge of crashing, hitting escape manages to cancel the render after a couple of minutes. I even tried different settings simple raytracing included for the second render but problem persists.

No it is not, in my current wip scene only 8gb from total 24gb is used by render but I have the same problem and it's getting very very counterproductive.

btw in Path Passes Corner Distance 200% is far too big. With that value you generate Path Tracing photons everywhere so time render will be longer. I think maximum should be 50-75%

Thanks for the tip, I am often leaning to overkill. I will try your settings.

Thank you.

This is the point that takes alot to calculate after the first render.

I have similar problem with almost all scenes, I render one frame in let's say a minute and when I try to render again the same frame or other the render time is multiplied 10 or twenty times. The only cure is to restart lightwave. Ok then, Tell me LW version and Kray version. It must something ext...
