LUMOS - no metric results shown #7

Open Alfie58 opened 1 year ago

Alfie58 commented 1 year ago

I get a successful rendering (of an object consisting of three stacked cubes in a heptagonal room with 6 luminaires). It takes 5min, which is fine. I've defined two metric points. However, the results are not available (just a list of the room metrics and points, see below).

The error message is:- 'Warning: Duplicate data points have been detected and removed - corresponding values have been averaged.

Any ideas gratefully received.

According to your screenshot, you have defined point 1 and area 2. Does LUMOS show you results when selecting those in the list? If not, please feel free to send me your example file and I will check what the issue is.

The error message: 'Warning: Duplicate data points have been detected and removed - corresponding values have been averaged.' usually shows up during meshing the room geometry, but there might be some issues during metric calculation.

Thank you. I tried to run it again and the metric calculation worked fine. Strange - I must limit my requests for support - am finding I am just making trivial mistakes. I do, however, seem to be bumping up against some limits of the program - for example, if I slightly rotate the object, the rendering has large black areas - whereas it works when the object is orthogonal to the lamps - but again, this could be just my lack of familiarity with the GUI.

Feel free to ask, you are a valuable beta tester and I appreciate the feedback. Concerning black areas, that sounds like a mesh error. You can try to increase the patch density, if that does not help I would like to have look at an example file.
