exact.. When you dont get enough photons in to a room it will look more like shabby occlusion but when (almost) every photon targets into the room through the window you gets faster light solution and higher quality of light. Yes when skyportals leave internal beta stage it will also guide finalgath...

Another doodle

Here is the first synthetic rendertest by Janusz of kray skyportals (guiding photonmap photons through a window). Both images rendered with same settings except with and without a portal. 3.30 minutes

Just a theory: You might have thought it helped since you used very low numbers of photons and since they are shoot random from time to time, you got lucky after you turned on occlusion and rerendered the leak was gone. Precache blur might also increase problems with more leaks in corners so i usual...

Looks to me like you have some light leaks on the wall with the window, and in the shelves...I'd guess it might help for you to make the photon map more accurate, and make sure you have Occlusion enabled in LightWave's Render Globals panel. What photon settings did you use? Occlusionsettings in lw ...

I post the answer here too: Oversampling will be added to GUI as it also is in for example blender/yafray but they call it refinement. Read more at http://wiki.yafray.org/bin/view.pl/User ... ayLighting

More samples always take longer time to render.

Thanx weepul, nope then it's ok since it's already one of the task.

Havent noticed this behaviour before, can you give some examples or scenes?

Work on skyportals are going well is all i can say at the moment

My honest opinion is that Vista plain sucks. If you have the ability go for XP64 and get a less cluttered/memory hungry platform. I run 64bit LW9.3.1 and Kray6.5 and it's the most stable version so far for me. No problems at all.

Wow alot of tips here and it seems youve got the hang of it
Could you elaborate more about : "-postprocess autoexp,.5; is awesome!!" ?

Thanx for your scene Juggernaut. Here is the setup the way i would do it. I added an hdri to the window (not necessary but i like the colour from it). I have divided the 2 windows into 2 partnames (could divide it more maybe?) and i also divided the 4 lightbulbs in those spotlights. Kray see's 6 lum...

Someone asked about geometry and here ive turned up the wolfram thread/the little glowing thingy inside a lightbulb into a a luminous surface. That tiny object is the only lightsource in the scene. I used luminous treshold min1/max1 so it's rather noisy but shadows are still very exact as you can see.

Now i have divided the 12 luminous objects into 12 parts and renders it with same settings as before but now krays see every luminous surface as one separate lumeobject so it reports 12 lumeobjects added. Starts to look much better. As a rule of thumb, the more luminous lights there is and the bette...
