Quote - There is no progress bar as lux will render forever if your computer lasts that long. Look at the bottom on the lux window and look of s/p (samples per pixel) that is your progress indicator. The minimum recommended is 500 samples but some times you may want or need to go higher. Also looking at your image will help out. If the image looks good enough for you, then hit the stop button.

 

Oh so it doesn't just end after a certain amount of time? wow okay ty
