Quote - i am sorry for posting bad posts. but i never was trying to complain.

i was just wondering if i am using wrong settings.

it was not a problem that it was not finished at 1 hour. it was strange to me that it looked so bad after 1 hour with so simple geometry.

Unbiased render-engine means to simulate the reality as close as possible. Lets have a look on your scene. There is a view into a room and an "infinitive world" outside. High and far away from your room is a lightsource, the sun.

To let you see something a renderengine has to send out "rays". This rays are "traced" and -simply said- a colorpoint is set where the ray colides with something. As said, the only lightsource from where rays are sent out is your sunlight. A real lot of the rays do not hit anything. Because your room is very small compared to the outside "world". A biased renderengine tries to optimize rays sent. An unbiased engine does not (like reality).

But because sending rays against nothing isn't that effective Lux has a method to give some hints to the raytracer. These hints are called "portals". Simply said a portal is a geometry (mostly a plane) that says: "Raytracer, all light to me!" Such portals are put where windows and doors are (where the light comes into your room). This helps a lot.

Beside of the portals, there are many more things you can do to speed-up your render or get better results. But the problem is, it depends on your unique scene. So you have to know something about Lux-.internas or you have to live with what you get.

At the moment this project is in an early alpha stage. It's not that easy to prepare a Poser scene to be used with Lux. But we are working on this problem. 

(Whoever means he/she could help with something: Just step in and do; even hints, findeouts, special know-how or script-snippets are important. This is an open project for all Poser users. The more know-how we can concentrate on this project the better is the what comes out at the end.)

I really wished my english would be better - sorry -
