Missing area lights in the lightmap

[m_stolley]

Hi, this is my first post and maybe it is a noob question but after i searched the forum i could not find the answer to my problem.

I have a scene where i have 128 area lights and want to make a lightmap for a game engine with kray.
But it looked like kray only calculate some lights but not all in this scene.
Is there a limit for area lights ?

Here i have a picture of the rendered kray image and next to it is an fprime render just rendered a little time but you can see that fprime render the lights and kray do not render them all.


And here is the lightmap where i marked the missing light in red.

Edit:
Ok, i can see that the lights in the second picture where calculated but the intense of the lights are so different but the lights have all the same settings.

All the lights have the same properties and none of them is off in the scene editor.
They are all in the same distance to the walls.
I use lightwave 9.6 and kray RC2 on Vista 32 bit.

Hope someone can help me.

Edit:
Ups, it is my second post.

So i figure out what i was doing wrong.
I just have to switch on area lights double sided in the quality tab )

I searched for a solution for three days now and now i find it by myself just after posting here.
Don´t know that area lights in kray are not double sided automaticly.

Maybe it help someone else.

You must remember about this: many thing from Lightwave are bad - I mean: forget specular, forget double sides Area lights, forget Ambient Intensity, forget Diffuse 100% (becouse this is unreal - maximum diffuse 80% for white surfaces, minimum 40 for dark surfaces) You must thing more physically - Kray requires this....

this is a fast render without light (only one of default as 0% intensity) and 225 luminous box at wall and 225 on ceiling (diffuse0% and 1000% luminosity)
